OFNA 1/8 Buggys v1.0

[elscotto80]

Lets talk 1/8's!!! I have an OFNA ultra gt with a O.S. RG .21 in it and its awsome!

[acidpee]

i have an ofna ultragt lx sompletely stock, was my first gas car, i love it, so predictable.

i broke a gear in my rear diff, so i made the rear diff a posi unit, and it seems to handle better!

[TeamCarnage]

I'm buying a MBX RTR, to race in a RTR class, no big mods can be made, what can a guy do to gain a small edge? NO noticable http://www.rccaraction.com/ubb/smile.gifmods are to be made.Any suggestions would help! Thanx

[acidpee]

tune your suspension, see rules on how you can cut body hols for vents and cold air intake for thcarb

[TeamCarnage]

ap-- any base setup advice...shock pistons oil wts. springs, I race on a fairly smooth track.What about diff oil wts? I never had a 1/8th buggy!!

[acidpee]

setup advice, hmm, well im not one to give advice without seeing what im giving it for, but do some practice runs, if its a smooth track, dont have hube knobby heavy tires, is it a short track? or a long track, lots of turns. etc, this ofna is my first 1/8 car, and my first gas car too... right now im spending must of my time with a traxas 4tec, i found a few other guys who have them, and 1/8 scale racing in my area, or 1/8 clubs is non existant right now, at least that i can find ...

[TeamCarnage]

AP- Picked up my Ultra MBX http://www.rccaraction.com/ubb/smile.gif The track has a series of sharp turns, some double jumps and 2 long straights the track itself is 190x90.My car has the 4 port engine(P4)My LHS idled 3 tanks thru it. more later

[MasterCrasher]

I'd like to be able to setup my Ultra GT LX for onroad too and was wondering if anyone has tried lower profile wheels and road tires. I was thinking if I could find an adapter for 17mm hubs to 19mm hubs I could run Landmax wheels/tires and reduce the diameter and get closer ground clearance. Any thoughts or suggestions??

[elscotto80]

That would be agood idea, or you could lower the suspension as low as it goes, that works too. I was driving mine on a parking lot and it was cornering like crazy!!!!!
Now for my question:
What is the part number of the spur gear for the GT LX, if you could give me the part numbers and the tooth amount that would be great. Thanks!

[CTRallyRacer]

Slap on a Kyosho Landmax body and it'll be a Rally car. WHOOHOO!

[ob4-kid]

Does anyone have the SST Blazer. I'am thinking about getting one with a 2 speed.!!!!

PS it going to have a TTR pro21 engine with a pull start.

[ofna_Kdog]

Hey guys, I've got an ULTRA GT LX. It has 2 cvd's in it right now...but since i snapped my 3rd stock axel this saturday...(**** ofna parts) I'm waiting for new cvds to come in. It's got the OFNA Delta Force 8 port engine. I've only run 8 tanks through it, and I haven't really gotten it tuned yet. But from what I've seen so far, it's not as powerful as the OS RZ or the RB engines that have the same HP rating. Any of you guys have this engine? What do you think about it? oh yeah, gotta dig the custom bumper! I'll sell you guys one for 20 bucks!

[elscotto80]

Nice buggy!!! When I get the chance i'll get a pic or two of mine. I am in th process now of changing my arms to pivot balls. I have a O.S. RG .21 in it and it flies, awsome acceleration and is very powerful. Got a question: Are you guys going through spur gears alot or not? Do any of you guys have the steel spur? Is it worth the 30 bucks? Well later dudes!

[SubaruTiburon]

I have a Hodr LX. I too am goin through spurs like a mad man. I hate that..8 bux a pop. I think im gonna have my uncle make me an aluminum gear. He runs a cnc lathe, maybe i'll have him make me some other parts..snicker snicker. http://www.rccaraction.com/ubb/biggrin.gif What i did after about 3 gears was loosen the center diff screws, that freed things up a LOT! But running 2 days ago i stripped another one for some reason, i think my chassis is twisting a lot.

[The Real Maxxter]

Aluminum Gear!? Ummm, that probably won't solve your problem. Aluminum is a very soft metal, and if you run your steel bell gear with an aluminum spur, you're going to have some serious problems. Hard metals and soft metals chaffe very badly when rubbed against eachother.

Have you ever worked on marine engines? Manufacturers love to use stainless hardware in an aluminum block. The hardware is almost impossible to remove sometimes. See if you can find a hardened steel spur, that ought to help you out much more than an aluminum one.

If you do run the aluminum spur, you stand a chance of breaking you crank shaft. When the aluminum chaffes, it will eventually build up to much heat and self destruct. It could potentialy wedge between your bell gear and spur and snap the end of your crank. I would highly recommend against it.

[elscotto80]

Sorry, thats what i ment, a steel one. I used the steel spur from RRP for my nitro rustler. Thanks for the input though!!!!

[SodTiwaz]

Hello fellow Ofna buggy drivers, finally got most of my worlds 2 back together after my lovely crash into a concrete curb...I'll try getting a pic up ASAP. its stock with an ofna/picco .21 in it, it was originally pull start but the one way went out and since i have to take the body of to pull start anyway (and then the fact that you have to make new mounting brackets or dremmel out holes in your chassis to put a pull start engine in. I'm simply taking the pull start off. Less work on the new chassis that way. Hopefully I'll be going down to the track this weekend so ill see if I can get some pics of it in action.
Also got a question for you guys/gals...before my crash i was playing around in a parking lot and my batteries to my servo's where going out, i throttled it to bring it back in and it started doing a gyroscopic spin pivoting where the center diff is, funniest thing I've ever seen...this 20 inch car spinning around at warp speed like a top, anyway was wondering if any of you had ever pulled this off...two things that may have made a difference is my center diff is locked so I have 50/50 spit on front and rear drive, and my tires where the stock one (lame pin style soft) and they where completely worn...not sure if that makes a difference or not.

[elscotto80]

Yeah, I've done that, don't do it too long because with another one of my trucks I did that and melted the diff. It looks pretty sweet though!

[MasterCrasher]

Well guys, here's what's left of my GT. Actually just repaired after a full-bore kiss with a curb that ruptured the fuel tank and caught it on fire. Took me a minute to remember that Nitro and methanol burn clear. Only burned my fingers a little, but I saved my baby!

[gtrunner]

where cn I buy parts for an ultra mbx on the internet?

[elscotto80]

www.towerhobbies.com (http://www.towerhobbies.com)

[elscotto80]

Hey guys, does any body know the part # for the screw that goes through the lower a-arm and connects it to the bearing hub? I reall need to know so it would be a great help, and oh yeah, its a GT LX.

[Lost Racer]

is its screw or the arm shaft?

[elscotto80]

The screw.

[ofna_Kdog]

Hey, just go down to home depot and buy a 4 x 20 mm screw. Don't buy hobby screws unless you have to...stores rip you off.

[simulatedwoodgrain]

Yo Elscotto!
How is that OFNA treating you? I hope it has been relatively trouble free for you. It was for me!

OFNA Kdog ..isn't getting ripped off buy the hobby stores what it is all it is about? LOL ..Kidding! They have to make money somehow!
Later,
SWG

[elscotto80]

Hey dude, whats up? This thing is the sweetest thing ever. I have run it into a ton of stuff and not one thing has broken. I have been going through spur gears like mad but it mostly because when i refuel the radio decides to give the engine gas without my permission and then by by spur. But any way, this thing jumps like mad and is so frekin fast. I haven't leaned it out because of my last engine, so I want this one to last a while, oh yeah, i'm still on the plug that was in the engine when i got it. Well I hope its all going t good for you, lata
Scott :D :D :D

[ofna_Kdog]

Hobby stores make sooo much money! it's not even funny! I want to run one when I get older as a hobby.

[Lost Racer]

Hey elscotto80, see if you can get a steel spur for that, so you don't keep going through them. If you can't find one, I may have mine still lying around somewhere. I upgraded to a torsen, so I don't use the stock one anymore.

[elscotto80]

Hey dude that would be gret if you could give me that, these spurs are really expensive. Well let me know or e-mail me at elscotto80@hotmail.com, thanks!

[XtremLosi]

alright guys... which buggy do i get??? I thought i was set on a xxx nt but the more i research these buggies the more i want one. I'm wondering which way to go... I'm looking at a OFNA Ultra world two... but also i've been reading really good things about the mp 6. opinions please!!! or should i stay with the xxx nt since this is my first nitro. (have had many electrics) thanks.

[Lost Racer]

I'll check again tonight..I had a rough racing weekend...

[elscotto80]

The MP's are very good buggies but tey are very expensive. If its your second nitro go with an OFNA. I have one and they are really good buggies, they can take a ton of abuse.

[Lost Racer]

Hey elsco, I ound the spur last night. if you send me your info I'll mail it out by the weekend..I'd do it before but I don't have any transportation during the week.

Email me at tcavaness@littonedd.com

[ 05-08-2001: Message edited by: Lost Racer ]

[XtremLosi]

thanks for the input... anyone else have opinoins between the ofna and kyosho buggies???

[Lost Racer]

I got your info this morning elsco. I'm going to try to send it friday..

[RichieRich]

What's an SG crank? Is that the same as a crank with an integrated pilot shaft?

[elscotto80]

Hey lost racer, I got the spur today, thanks a billion man!!!! That is really nice what you did!!! :D :D :D :D :D

[Lost Racer]

No problem, anything to help a fellow racer out :D I'll email you when I need it back LOL!! ;) enjoy it.. :D

[morfeeis]

lost race long time no type

i have almost made up my mind to get a 1/8 buggy.. i think i will be getting a Ofna Ultra MBX Nitro Buggy Special Edition, i found one on e-bay that i likr.

from what i have read the front servo needs to be replaced.. i already have a high speed air servo so thats no prob is there anyyhing else i should know before i get this buggy?? ie stuff i need to get are weak points on the car..

have not seen you at the rccarboard in a while

thanks to any that reply

[Lost Racer]

Hey morfeeis,I was just on there yesterday boasting about my getting my Rally car going.. :D As far as the MBX is concerned, from what I've seen its a very solid buggy. One guy about 2 weeks ago bought his MBX on friday and was racing it on saturday. The only thing he broke was his pullstart. Other than that its great! Oh one other thing, try and stay off the wing, the mounts that thing wing slips on to seem to be a bit weak. I've replaced mine twice. Now I just have it zip tied :D

[morfeeis]

HOW HARD would this motor be to tune from a guy that sold a whole car with a rossi cause he got sick of the motor acting like a %%$#%&%

http://abacus.sj.ipixmedia.com/abc/M28/69007436e684775eca79d1f3e9/i-2.JPG

[elscotto80]

I would say not that hard, just the basic tuning how-to's. Just don't go too lean and your in bussiness, I know someone with the ngine and its a real nice one, just be sure to take care of it.

[morfeeis]

OK i had made up my mind but now the lx gt rtr and the mbx rtr look good to me and after reading rcnitro i like the mbx r2 (o my head) :confused:

which one do i get which one is the best basher and which one breaks the least?? what about the pirate 10 is that a good buggy i fell like the lost want to racer :D

[morfeeis]

after looking every where for a good 1/8 i think i found one and at the low low price (yea right) of $300 it is a rtr gtlx

but i dont get that motor r the rx pack but i do get 2 servo's and a radio so is this a food deal r a not

by the way the motor i get is an ofna hyper .21 is that a pull start r not cant find it anywhere



------------------

one day neo your gona realize the truth just as i did there is a difference between knowing the track and beating the crap out of everyone at the track

[elscotto80]

Sounds good to me, I paid 250 with an engine, no radio and alot of extras, so i'de take it!

[seatec1]

I recently bought the Belted OFNA Slicks for the LX. They off course didnt com with foam inserts. For the life of me i cant find anyone who can sell me the right foams for these tires. I already tried the foams that OFNA offers right now but all of the seem way to tight to put in. I checked the stock tires and they seem to have some ratty foam inserts that look like a rat knawed on it. I also cant seem to get in touch with the OFNA folx ( david?) via email. Any help is welcome.
Seatec

[morfeeis]

have you tryed the ones for the mp line of cars

[seatec1]

No i have not. ill check my lhs for them. Thanx for the tip

[Lost Racer]

What do you guys think of the new rear suspension on the R2? Likes or dislikes? Advatages or disadvatages that anyone can see? Personally I like the new rear setup. It gives you more control of the setup on your car. For a newbie unfamiliar with setting up, I'd recommend the current MBX and suggest the upgrade when they feel comfortable with the tweaking.

[morfeeis]

well i made up my mind (for the nexrt five min's anyway) the car in the pic's will be mine it is a gtlx so i am now in the club woho!!!!!!
soon as paypal send the money to my bank(that i just sent out yesterday) i will pay for it and should have it by not this monday but the one after that

i cant wait to run after the cats around here he he :D :D :D :D

[morfeeis]

can i upgrade the gt lx to the mbx not the r2 just mbx

i like the way it looks but it ant fo me before i get all into set-up's i need to learn how to tune that monster .21

i think that is the reason i went with the gtlx no balls to worry about i happen to like the old set up

[Lost Racer]

Looks good morphheis. I think you'll be happy with that. :) Just get out there and start flying! Over jumps that is :D

Hey elsco. Did that spur gear workout for you? I hope so.. Have fun.

[ 05-23-2001: Message edited by: Lost Racer ]

[elscotto80]

Yeah I think you can, its like 50 bucks, though, but well worth it as my LHS says.

[gomezextreme]

Ya i saw front and rear complete suspensions for a LX on E-bay.Cheap!!!

[gomezextreme]

I am also thinking about an SST i mean $199.00 how can you go wrong?Ant ideas about this purchase would be apreciated.

[Lost Racer]

I know they have an upgrade to the Worlds model. I think it runs for $100, not positive on the price. But it gives you the suspension and some other goodies.

[ttrcr eb4]

EB4 RULES! :D ;)

[NickBurns]

Hey guys,

I just got an Ofna MBX, it should be here tomorrow! How does this buggy compair to a mugen,kyosho or Eb4. Is there hop-ups i can buy that will make it as good as these buggies? Also any recomendations before I run it? Treadlock? Should I buy street tires if I'm going to run it on the parking-lot most of the time, and then put the stock tires back on for off road? Thanks

Ian

thank you for such an informative statement


---------------------------------------------


hey nick i am not as far as you i still need to make up my mind ... but from what i have read thread lock is a must on any metal to metal screw or nut.. yes getting some extra tires will help you out a lot (speaking of tires seatec1 did those mp inserts work??) if you got the mbx ready to run you are gona need to get a new hi speed metal servo for the front end

[ttrcr eb4]

lol :p

[Lost Racer]

Hey Nick,
If you want to be competative with that buggy, the NUMBER 1 thing to do is to learn how to control and drive it. Learn your buggy so you know what the weak points are and how to improve upon them. Only then will you be competative. Don't worry about hop ups just yet, unless you're just trying to make your buggy look pretty.

As far as threadlock goes..Just like Morpheis said. Any metal to metal contact. With the exception of the engine mount screw to the chassis. But I think that is a split between some people because of engine movement from vibration. I however don't do it...anymore. I stripped 2 screws trying to get them out after using it. Then I picked up Ofnas engine mount screws with the concave washers. They are VERY good and will not move. Just don't over tighten :D. I've said wuite a bit now; so for the last question about tires. I keep 3 sets of rims and tires. 2 offraod type and one street set. I don't know about you but I don't have $50 all the time to buy new tires. And if you run your offroad tires onroad, you will be replacing them really quick. But thats up to you. Enjoy your buggy and have fun. :cool:

[Lost Racer]

[Ofna Ultra Worlds II Buggy] Handling question guys. I have Torsens in the front and center, and I'm running 3000 in the rear diff. I hae a HUGE amount of oversteer. I'm talking about my car pulling 270's into corners...I've tried slowing down but that seems to make it worse. My rear end just swings out in front. :confused: Should I loosen the brakes a little in the rear or what? I'm at a loss for thoughts right now...thanks.

[ 05-30-2001: Message edited by: Lost Racer ]

[morfeeis]

lost racer youlost me

i wanted to know how much am i looking at for a wt of new tires and rims i want some for offroad i looked on tower and they dont list any wheels or tires by ofna

by the way this is for the gt lx if you guys know a site where i can look this upo for my self just give me a link

[Lost Racer]

Sorry about that, :p here you go morpheeis http://www.ace-hobbies.com www.horizonhobby.com (http://www.horizonhobby.com)

[morfeeis]

wow they have a lot of great tires what do you think would be a good set-up for just bashing (offroad) what tires that is


i will be running in alot of hard packed dirt and some sandy like dirt but most of the time it will be the hard stuff

[Lost Racer]

As far as tires...I went with the Proline Dirty Harry XLs..Very good on hard packed AND soft!! response is unbelievable. As soon as I fix the fishtailing..hehe

[morfeeis]

sorry about the bugg

hey what where you going to do with another one anyway

should i get the p4 arnt they around $120

[Lost Racer]

don't worry about it. I was going to convert it to an Ultra GTP. I bought all of the parts except the body to do my worlds, but I got lazy and have everything sitting in a box. I may just try to get a GT LX just so I can do it. The P4 is a good starting engine to go with..Then once you get the tuning down, upgrade to something a bit more.

[ 05-31-2001: Message edited by: Lost Racer ]

[Lost Racer]

Anyone know if Manufacturer shocks are interchangeable..Say I want to a mugen shocks for my Ofna..Would they work?
Same with the springs and pistons.

[morfeeis]

if it';s anything like ae and losi (i putting losi shock's on my gt) then it should work fine

what car gtlx mbx i think you have the mbx right?? :confused:

[Lost Racer]

Worlds 2, but I think they all fit..Unsure though..any insgiht?? Anyone?

[BlackWolf]

A friend of mine has an OFNA Pirate 1/8 buggy. In my life, I've never seen this car for sale anywhere, nor have I ever seen spare parts for it. It's NOT the monster truck. I was hoping maybe the Monster Pirate parts would fit. Who knows. I was going to buy it from him, but if parts are scarce then forget it. I mean, from what he says parts are impossible to come by. He actually had to MAKE new gears for it on his Bridgeport machine (mill) because they're non existant.

[NickBurns]

Is there a way to convert your ULtra MBX or GT LX to a Worlds II? THanks

Ian

[Lost Racer]

Blackwolf- I think the Pirate is a 1/10 scale buggy produced by HaoBao for Ofna. Look like this? http://www.ace-hobbies.com/Images/Ofna/P10_Series/index.html

NickBurns-Worlds II Upgrade kit..I think its like $100-$125...Might want to check your LHS. But they do make one.

[ 06-01-2001: Message edited by: Lost Racer ]

My LHS doesn't support OFNA, does anyone know if this WorldsII Upgrade kit is available online anywhere? Thanks

Ian

[elscotto80]

Check Towerhobbies.com too, they have a good deal.

[morfeeis]

cal ace and see if they can help you out

[morfeeis]

towwer wont help unless you have part# there more like a company then a hobbyshop

[vetrider]

Hi everyone! New guy here from S.E Alabama. I just found this forum and it should fit me well. I have a Worlds II with a OFNA P6 and RB CS Sport engines, Hitec Lynx 3D Spectra, Hitec 605MG servos (better ones on the way). Here's a pic or two with P6 installed. Or you can go here for more on me. http://vet_rider.homestead.com/
BTW Lost Racer, I think you can go to 1000wt silcon oil in rear Diff to keep the rear more in check in the turns. :)

[stormperson]

are the worlds 2 and the new mbx r2 the same car pretty much, what are the differences? thanks!

[GT]

Black wolf, just to help you out, Ofna did make a 1/8 buggy called the Pirate M-1, it is really old (10 yrs. at least) and It won the '91 Kyosho 1/8 scale gas Challange piloted by Cliff Lett. (Won RCCA's Top Ten Pick for 1/8 scale off roader in May '92).

[GT]

Nck Burns, Try www.Nitrohouse.com (http://www.Nitrohouse.com) www.ace-hobbies.com (http://www.ace-hobbies.com) (or call)

[vetrider]

stormperson, I don't know all the differences in the MBXr2 and Worlds II but some are that the MBX has Pillow Ball Suspension in the rear as well as the front and no kickup in the front chassis. If you go to the OFNA site they have made some changes and seems like the Worlds II and GT LX is not offered anymore. http://www.ofna.com/index.htm

[stormperson]

is there any handling differences between the pivot ball and the non pivot ball?

also does chassis kick up a make a noticable difference?

[morfeeis]

i think lost racer said something about that a few pages back he said they or more there just to dial in the set-up on the car you get far more tuneing optins with the balls

if what i read in rcca is right(buggy not here yet) then that kick up will not give you that much of a prob unless you or in a full scale race

they did say that they took it to a bmx track with no probs at all and nothing came lose AT ALL NOW THAT IS A TANK

[vetrider]

morfeeis, I think your correct about the kickup. I know it helps on real rough tracks and when you let the nose drop on landings but other then that it shouldn't make too much difference. Much more adjustability with Pillow Ball suspention.

web page (http://vet_rider.homestead.com/index.html)

[elscotto80]

Hey guys I just wanted to let everyone know that I am very pleased about the response to everyone, its been really great, keep it going!!!
Scott

[morfeeis]

i was also thinking of getting the MBX or the MBX r2 but i went with the gtlx cause i wanted to lean how to drive first and then when i was ready to get into set up's then i would get the front/rear Pillow Ball suspention upgrade

one other thing that made me get the gtlx was that the MBX and the r2 had no kick up now i was just wondering would it be posable to switch the gtlx and the MBX chassie's so the you could get the kick up that you wanted
============================================
come to www.rccarboard.com (http://www.rccarboard.com)

[stormperson]

since most of the tracks that i would be driving on are rather rough, i am really going back and forth on the buggies due to the kick up issue.

now, does the kickup only matter because it allows the buggy to go over stuff easier or does it affect handling in a very noticable way?

[morfeeis]

it affects handling by dig in if you have a bad (nose first landing) which can send the can anywhich way. now if you where bashing then this is not that big of a deal but in a race this can effect the whole outcome...if my idea (look up) works then that would solve the problem ... are you could just get the worlds 2 and add the ball set up to that (wait dose the w2 have kick up???)

[NickBurns]

The GTLX doesn't have a kickup either does it? The MBX and GTLX are almost the exact same cars.

[vetrider]

I believe that they both have no kickup. The MBX has upgrades over the GTLX but both are good yard runners or track racers in RTR classes.
The worlds II has kickup like the Kyosho's and Mugen's.
I love my Worlds II. Just add rear CVA'a a good motor, radio, Silicon diff oil and GO!!!

[stormperson]

i have always been a big believer in you get what you pay for, espically in rc's. however unlike in most other classes, 1/8's all seem to have the same thing going on. none of them have new suspenion angles or new layouts, all are pretty much the same. i can see kickup as being something different though.

however, for $250, is it really worth an extra $100 to get kickup.

and i personally rather not have a pivot ball suspenion, that means an extra 1-2 hours of work making sure its set up propery each week if not more.

oh, i was checking out ofna's website, they just changed it!
they basically are just showing off all their new stuff, dont even have the worlds 2 on the site

[morfeeis]

OK then what about buying the w2 chassis and swapping it with the mbx's or the gtlx


i saw that storm i hate when companies do that it makes you fell like you have to have the newest car

[TeamCarnage]

Vetrider- Welcome to the board! How do you like your engines? I've got an MBX with appx. 3-3.5 gals. thru it. It's the P4.I'm not thrilled with with this powerplant,but I race in a RTR class and options are limited. Both engines you have are acceptable replacements,I'd appreciate some feedback.Nice pix of ypur buggy!! Nick

[morfeeis]

cr5anage

that is the motor i am getting is it to slow for the size of the buggy, i will have it in a gtlx do you think that would be a good motor for my first .21 or should i get the p6

ps this is alos my first 1/8

[vetrider]

Thanks TeamCarnage, You and morfeeis will be very pleased with the P6. I've got it in the car now and it runs great, easy to tune and the powerband is plenty wide. Price is better than the RB too.
I don't have the RB in the car or broken in completly so I can't give comparison. ;)

[TeamCarnage]

morfeeis-The P4 was a decent engine to start out in 1/8th scale.I just run it x-warm for it to make good power.(260-270)I never tried other pipes, could make a diff.A guy I race runs the P6,noticable difference.1/8th scale is'nt like my GT,I'm happy with my OS CV,more than enough power for me,in 1/8th you want as much power as you can get, $$$$.
Big difference btween 1.7hp and 2.5+ Its still a blast!!!!

:D

[elscotto80]

Any one know the rating of horsepower on an O.S RG .21, haven't run it much cause my radio batt. is shot. And are any of u guys from MD, I am and if u want to hook up i'de love it(this should be in regonal but steve don't delet!!)Lata
Scott

[stormperson]

i think its around 2hp.

EDIT: just a quick question, do all 1/8 wheels, such as the ones made for the 7.5, mbx4 and ttr buggies fit the mbx r2?

also is pivot ball more durable, and does anyone make aftermarket parts for ofna buggies.

and finally: if i were to get the worlds 2 chassis, with the kick, do you think it would fit in, or would i have to mod the upper deck, and possibly install a turnbuckle instead of the bridge between the trapizoid or is it hexagon thingie, and right before the brake's.

also (almost done) i know the worlds 2 has 4 sets of brakes, that can be adjusted, should i assume the mbx r2 has the same set up?

final question (insert music here....)

should the "crowd pleazer" 7.5 body fit the mbx r2 okay? (stock one looks like crap)

thanks!

Hey guys,

I just got my MBX yesterday! Break in went a little rough at first. I am very new to nitro and my roomate who has some experience went home for the weekend. Needless to say I didn't really have any idea what I was doing. I guess the throttle was open to much when I first turned on my car. So I went to start it for the first time and it starting reving really loud. I knew this was really bad so I pinched the fuel line and stoped it in under 5-7 seconds. After that I couldn't get the engine to start for like 8 hours. It was WAY to rich and just kept flooding. I left for a few hours and came back and gave it another try and it started to work. I ran it very rich about 8 turns out from the starting position. I broke it in over about 5 tanks of gas, letting it idle for 2. I am slowly leaning it out as I go. The screw is still about 6 turns out from the starting position. How far can I lean it down? I've herd 2 revolutions out was a good idea but that seams like a FAR way away. Right now the head is not hot at all, i can put my hand on it. My spit does not boil off. One funny thing that happened is that the wheel nut came off while I was running the car and the wheel passed the car at about 30 miles per hour. I put some threadlock on the nuts after that. I also purchases some Proline RoadRage tires from my LHS so that I would not ruin the ones that came with it. Do you guys have any other suggestions for me. Do I need to threadlock more then just the wheelnuts. I figured it was done at the factory. Can I improve throttle respone by ajusting that needle on the side of the carb? Thats about it, Thanks. Later.

Nick, It sounds like your not going to burn up the engine for SURE :) But, one of the things an engine needs during Break-in is to be HEAT cycled. That is, the heating up and cooling off of the engine components let them take set and run true. Check the engine manual that came with the car and set it to what they recommend for break-in. If it's not listed, then just add a half (0.5) to one (1) turn out on the MAIN needle screw. The one beside the fuel line connection. Set the low speed screw flush with the collar and then in 0.5 turns. This should get the heat in the engine but not so much as to burn it up.
Keep us posted. :D

what are the most comman parts that people break, and that i should stock up on?

[NickBurns]

Hey guys

I think I might have a problem. I just got my car so i'm not really sure what all the parts are called. In the rear end a drive shaft goes into the gearbox. Where it meets the gearbox there is a little cylnder that the drive shaft fits into , and then this goes into the gearbox. Every other place where this connection is made(front end, etc), this cyclnder that holds the drive shaft is flush, but in the rear end its like almost just hanging there. It also will not turn the clutch gears when i spin the back wheels unless I hold this peice flush to the gearbox. I also found some hard black crust(burnt grease) coming out of the gearbox. Any ideas, or need more info? Thanks a lot

[TeamCarnage]

Nick- I too was excited to get my MBX broke in and to the track.After 1/2 a tank of easy driving, my outdrive loosened up just like yours. I did what everybody should do with any RTR, tear it down and locktight everything.I use blue because I take my car apart after every race weekend(4 qualifiers,1/2hr. mains). Nothing comes loose! When you tear down your buggy,clean out the grease and refill with silicone diff fluid, I'm running 10k in the center,7k in the rear, 3k in front BIG difference!!

[ 06-09-2001: Message edited by: TeamCarnage ]

[vetrider]

TeamCarnage, Is your driving style to keep the rear end hanging out most of the time. The cars not yours! HAHAHA :D What i mean is with 7000 in the rear and 3000 in the front the car should be oversteering in all the turns and somewhat squirrly on the straights.
Doesn't matter, if that's the way you like it, "Just Do It" :)

[NickBurns]

Thanks TeamCarnage,

I took the rear end off I guess the seal on the bearing that had come off and was making the bearing lop-sided. So I put the seal back in, then locktied the screw back into the drive shaft thingy. Its a good thing I did it becuase it was starting to melt away the planstic on the gearbox! Thanks. Do you think I need to refill the diff with grease? It doesn't look like much is in there. Take it easy.

Nick

[NickBurns]

Ok new problem :confused: I put the rearend back together, but I don't think its working right. When I roll the front 2 tires on the ground it only turns the back left tire. It should turn all 4 right. Its like my back left tire is not being powered. Any idea? Thanks.

Nick

[NickBurns]

Well my car seamed to be running fine even with the problem stated above. I spent 3 hours taking apart the rearend and cleaning the rest of my buggy today. I take it outside for a testrun and my girlfriend asked to try it and ran it into a light post. The lower Arm broke on the front end. Anyone know a place to order parts that is close to upstate New York. I would order from Ace Hobbies but it takes 7 days UPS ground. Thanks a lot.

MAN I go away for a week and you guys just flood the board!! Whats up? :D Hey team I had 3000 in my rear and just switched to 1000. But I'm also running Torsens in the front and center. But even with the 3000 my rear end was everywhere from where it should've been! I tried 7000 in the front just for kicks. Snapped the pins in the sun gears, but yeah it does oversteer like mad!! :eek:

I just got an OFNA GTP (used) Saturday. It has a 2-speed transmission. I want to use the OFN33002 kit to upgrade it to a Blazer Monster. The problem is that ofna recommends that you don't use the 2 speed on the monsters. I assume that it is because of the gear ratio changes with the larger tires. So, I need need to either replace the clutch gears or the spur gears.

The clutch gears are already the smallest 13/17t, and the spur gears are stripped. So, I would like to replace the spur gears with some larger metal gears. I would like to find metal spur gears larger than the ones that ofna sells, but I don't know if there are any third party gears that will work.

Anyone out there have any ideas?

[Nitro Action 1]

I am looking for a 2 speed transmission for my ofna gtlx buggy. What transmission would fit it? thanks! :D

[vetrider]

No problem, TeamCarnage. :) I was messing around with my HPI Super Nitro and put sticky tires in front and reg in rear and man did that thing oversteer like crazy! :eek: So, Lost Racer, this is similar to what happens with our diff fluid.
I have 5000, 7000, and 3000 front to rear in the worlds II and it handle's great in loose thick dirt and grass. On a harder slick surface, I think I would drop to 1000 in rear and go to 10,000 in center. Maybe 3000 in front also. ;)

[Lost Racer]

Hey Nitro Action-
If you're gonna run mainly onroad, Ofna makes a 2 speed the that car, it runs for about $100. But if you're gonna be running offroad, forget about it and get a steel main gear instead. From what I've seen, 2 speeds and offroad don't mix very well, you'll be stripping gears like mad. But like I said, running onroad go ahead. But offroad think twice. The replacement gears aren't expensive, but just to replace them all the time gets to be. ;) I'd suggest going with the steel main spur instead and save the stripping and your wallet. Somehow that last statement just doesn't fit :D.

[TeamCarnage]

I figure more than a few people are reading thru the Ofna post. I was wondering what hop ups u guys have done? My Ofna car is the Ultra MBX,so far I've put diff fluid in, canned the reciever box and mounted the reciever next to the battery(Trin.1100 NiMH) under the radio tray.I stiffened the chassis with a 5/32 Al. rod from the rr.diff to the center diff. FMA st. servo,Dirty Harry rubber,JR3 Tx Rx Whats Next :)

[NickBurns]

Hey guys,

I am buying a new body, how do I know what one will fit on my MBX. ?? THanks

Nick

[Lost Racer]

I believe the GT LX body will fit. I tried it on my Worlds II and it was less than impressing. But it is a different style as well. But the MBX is geared off of the GTLX model so it should fit.
Ofna Ultra Worlds II
As far as my buggy goes as hopups:
Torsen Diffs Front and Center
Hitec 5945 DIgital COreless servo for steering
Hitec 605MG on throttle
JRX3 Radio Gear
Dirty Harry Tires on one set
Ofna Excel's on another set
Ofna Wide street Tires on the last set
CVD's in the front and rear
Ofna Force P4
Ofna\Picco Comp
No real eye candy... It comes just about hopped up as needed anyway.
Whew outta breathe. I think thats it anyway...

Hey,

I am going to be racing my MBX on pavement this weekend. There are no dirt tracks around, but lots of people race Touring cars, Stadium Trucks and stuff on the street and they said I could bring my buggy. Do you guys have any tips as far as tunning my car for the street? I have a set of pro-line road rage tires that I use. I was also thinking about taking all the spacer out of my shocks to give it lots of suspension travel. THanks a lot.

Nick

[morfeeis]

i can tell u this much the last thing you want while raceing a buggy onroad is more suspension travel i say stiffer shocks thicker oil shorter shafts and slam that baby if you want to go that far other wise just lower it and takeem out dont forget u have a .21 :D :D :D

[Lost Racer]

yeah...what morfeeis said! :D

[NickBurns]

Thanks for the reply, I also ordered some stiffer shock springs the other day, I will put a few spacer in tonight also. How do you think a setup like mine, MBX,RoadRage tires and those few suspention ajustments will do againts those 1/10 touring cars and stadium trucks? Thanks.

NickBurns

[Lost Racer]

remember those cars are a lot smaller and can probably out manuever(sp?) you. But you may be able to get them in the straights..do you have sway bars in the front and rear?

[morfeeis]

i just told u you have a .21 you also have 4wd and best of all u can run them over

on the real if you set the car up then it should do just fine... but trust me on this one no one in there right mind with a nrs42 will try to push u out of your raceing line :D :D :D

[NickBurns]

I have sway bars on the rear. The only time i've ever flipped was on the grass.

Hahha yea, I bet an RS4 going fullspeed would move my buggy about 3 inches. I should just try and wreck all the other cars before the finish line :)

[elscotto80]

what he said...
I don't know wht i'm saying, just wanted to say something since i haven't in a while.

[TeamCarnage]

LostRacer-Did you go thru 3 engines? I've got 3 gals. thru my stock P4 and it still has good compression. Which of these 3 engines were you happiest with? I'd like to give the RB a try.Would you give it a high rating? N.B.-- I never even considered running my "offroad" buggy in street trim :confused: theirs a reason why my sons and I post under this name, a closed course would be a smorgasbord with 1/10th scale cars..Have Fun, thats what its about ;)

[1134]

Two speed transmission on monster

Like I previously posted, I have a GTP w/ 2-speed that I want to make a monster. The current gears are 13T/17T (clutch) and 49T/45T (spur). Just to compensate for the tire diameter change from 4" to 6.67" you have to increase the spur gears to 81T/78T. Now if you want to compensate for the diameter of the tires when they expand assuming a conservative 9", then you are up to 110T/106T. :eek: Probably a 96T/92T would be ideal. If I didn't already have the 2-speed (and not even the origional single speed), I just gear it down and let the increase in tire size act as increase in gearing.

While in the local hobby shop, I saw a couple of gears (84T and 81T) for a losi. Does anyone know if these fit on a ofna shaft?

If I can't find some larger gears soon, I may just have to put some buggy tires on and forget making it a monster for now. :(

[NickBurns]

How fast does the GTP go with a 2 speed. RCCA said they clocked it at 42mph and he though it could go 60 with a 2 speed. Later

NickBurns

[NickBurns]

Lost Racer,

I also have a p4 that came with my MBX and it seams pretty good. How quickly are you expecting it to lose compresion. Also what is your needle settings at, I am running mine super rich, like 6 turns out. For some reason it has a hard time starting if I make it leaner. It will run fine, but when I turn it off and take it out the next day I have to richen it up to get it to start. How fast do you think a p4 can go? 50mph? Beucase I know mine is not going near that fast. Hopefully I can tune it up today because my new arms should arrive today! Thanks.

Nick

[1134]

Speed of a two speed.
I was told 80 by the person who sold it. :) I haven't seen it acutally even go yet, it's gears were stripped when I got it. I would suspect the real speed is somewhere between the two. Unfortionatly, the manual that came with it doesn't list the number of teeth in the transmission gears. Sometime when I have them apart, I'll have to count them.

Also, the gears that were in it were the lowest gearing that ofna has for it.

Also, there isn't a close place to run it down here. Maybe I'll have try some different gearing and go up to the salt flats. :D

[1134]

BTW: it is a P4

[Lost Racer]

1134-A P4 will be unable to produce 80mph..It just doesn't have the UMPH! Even with the 2 speed. From reading throughout other posts I've come to this conclusion on 2 speeds( :confused:Please, anyone correct me if I'm wrong or add to. :confused: )A 2 speed will get you up to top speed fast than a single speed, BUT your top speed increase is not by much. If you want to throw numbers out I've read any where from 3-8mph pending on the gearing. The P4 is a GREAT engine!! But is not made for topend. Its made for offroad and torque. In which it does great at both. If you want to try for a higher topend, check for a higher gearing ratio w/ofna and go with a higher performance engine. :D And most of all, HAVE FUN!!!!!!Besides You'll strip your 2 speed more often offroad and never see the topend anyway, too much on and off the throttle. As I stated earlier enjoy while it works. :p

Nick-That engine will last you a good while if you take care of it...Did you read TC's post? 3 gallons!?!? That man must be an engine god!! ;) As far as my needle settings go, I've NEVER leaned it out. I will be this week though. I have to tune it for a local event coming up.

More trouble. I got my parts in today and put together my buggy. I took it outside and ran about a tank through it and it was really sluggish and slow. I took it back in and saw that in the drive shaft going to the rear end the bearing had poped out and was just riding on a thin plastic edge. THis in turn made the drive shaft connecter come lose and it was just spinning. So while i was taking the rearend off i notice that the back left tire was totaly LOCKED up pretty bad. I was afraid that my diff had gone bad but it was the bearing on the tire. How could this of happened? I can't even turn the bearing with my fingers. Is there any way to fix it or do I have to get a new one?

Thanks

Nick

[Lost Racer]

TC- I've only gone through one new engine, that was my RB S7 Europa. It snapped the conrod after 3 months. Very nice engine though. Full of power. Unfortunately at the time I bought, I was still a newbie and didn't know ANYTHING not a SINGLE thing about gas RCs. So when I'd run it the air filter came off occasionally, and I didn't think anything of it. My friend drove it into set of bushes, flipped it , then gunned it, all with the filter off. And I think thats what gave me the end result. Other than that, my P4 I bought on ebay NEW. The compression on it is still incredible and i've put about a half gallon through it. I tried going to the P6 but have had no luck tuning, and I need to get a new P/S for it. The RB engine I have now has icredible amounts of power, even for a 3 port. The ONLY problem I have with it, is that the button and head are one piece. AND the top hallf of the button is stripped out. SO only certain glow plugs will work..Still looking for those plugs. :( At this time my P4 has some play in the conrod, so I'll be changing that tonight. :D To be fair about rating these engines, the only one I can truthfully hold to so far is the P4. Until I shell out to get a new P/S for my P6, it will be sitting in my box in the case aof an extreme emergency. :)

1134- As far as 2 speeds go, I think ofna's are the only ones that fit. I have heard too much of anything about others possibly fitting. You metioned something about Losi...I didn't know they made 1/8 scale anything..You can try to see if Kyosho has one for the Landmax, if so try getting some info on that one. I'm solid on my answer, but it is an answer. :D good luck!

Your welcome. I wanna see you get that thing running. And I know how it feels to get a car and not have exactly what you NEED to run it. Hence my Z10 Rally for 3 months w/o an ESC...I had the motor, radio gear. Even the body!! But no ESC..I was itching to drive it like mad!! Then I get my ESC and get ready to install everything, found out I needed a pinion gear!! Oh the HORROR!! My first electric car and it was taking me forever to get running. Now its running and I'm having the greatest fun with it(except for my Worlds 2).

Nick-Your Car is RTR correct? Did you happen to go over the set screws with loctite? I've had that happen before on the drive shaft, but that was after about a year. I took the car apart, and ALL of the set screws out cleaned them and reapplied loctite. Also clean whatever they're going into there will be dry loctite in there and there may not be a TRUE stop for the set screw. Hope this helps.

Well i final got everything together today and my roomate and I went out driving for awhile. I would say I got about 6 tanks in today. There was this huge parking lot on campus and at the very end was a small grass hill about 5 feet high. I had never done any jumping and I took it at almost full speed. My MBX went flying about 20 feet, and I let off the gas and the car ended up hitting the ground at a 90 degree angle. The only thing that happned was that the engine slipped forward away from the spur gear. (Should of had a top on). After that I fixed it and tried to jump again, I start it up and WAM it takes off full throttel. I had forgotten to turn the radio on. The car ran right into a swamp about 200 yards away, lucky it has been really dry and there was only about 2 inches of water in it. After that we did some more jumping and I broke off the Wing Stay. I have a few questions for you guys. A) Can I buy the wing stay alone or do I have to buy the whole wing mount. The Wing stay is only a little plastic peice about an inch long. B) The stone disk for my front break is gone, its just disapeared I have no idea how it could of gotten off. C) The Bearing that goes into the rear diff from the drive shaft keeps coming out of its plastic hole, its almost totaly exposed. Thanks a lot.

but i am loving that new m3 with the m5's v8 wow what a car what a birthday present i get to watch 24 hours of raceing all

one good thing i did spot is that i got a steel spur gear which is real real good

[TeamCarnage]

Nick B.--Ilooked in my MBX manual,it looks like the wing stay is a complete unit#30270..$13.50 list. I lost my front disc during my 1st race,I didn't miss it till after the qualifiers,Ofna makes 2 grades of disc material,I stuck with the cheapy,and have had no problems since.The high end buggies use metal disc then attach fiber pads to the calipers. That would be next,but I'm pretty happy with the braking I have now.As far as the diff bearing,the outdrive should hold the bearing in the diff housing,loosen the set screw,push it all the way inand tighten it back up.Hope this helps.... You guys running P4s,,I wasn't BSn about having run 3+ gals. thru my MBX,I broke it in slow, but after that I beat the heck out of it!I run it HOT tomake good power (250-280).I race every weekend and practice 2-3x weekdays when possible,I'm no Leblanc, Guess theirs some good fortune smiling at me :) I'll take it!!!

[NickBurns]

THanks TeamCarnage,

I broke a front Arm ******* AGAIN today. I was racing my roomates RC10GT around this course we had set in the parking lot. I ran a corner wide and ran right into a cars tire at about 30mph. I guess this kid was watching and he came running over to make sure his car was ok. My rear diff connection is acting ok I might have to tighten it up again. Anyone else running into a problem where they strip plastic screw holes. I take my car apart quite a bit and I've already lost the threading in 2 places :( . What hop-ups do you guys recomend for the MBX. My steering servo is starting to act really funny, would I notice a difference if I bought a better one. Later.

Nick

[ 06-16-2001: Message edited by: NickBurns ]

Thats funny, my car came with some stripped screw holes when I got it!!! (all bottom shock ends, all torsion bars ends, and a couple of diff housing screws). but I replaced the shock screws with screws that were more course. Definitly get the alu. steering servo arms, steel spur. That ***** the wing stay comes with the whole wing mount, I've got like Three mounts laying around some where... those wing stays are weak. I just try not to land on the wing so much any more! LOL

[morfeeis]

strip plastic screw holes

this wont help you this time but maybe next time if will ... to prevent striping out those plastic parts all the time (like i used to with my RS4 NITRO) a guy online told me a little trick ... before you start to thread the screw in twist it ccw till you fell it drop in a little.. that little drop you fell is the screw falling back into the previous threads ... this helps the screw socket out a lot so that you or not cutting a new thread every time that you take out a screw hop that helps

[NickBurns]

Thanks morfeeis that tip worked awsome.

My servo blew today so I had to get a new one. I got a hightech 605 and its a HUGE different over the stock one in my MBX. Its almost like a new car. I was flipping the car over left and right with this new power stearing. It seems like something is ALWAYS breaking on this car. I've spend like 300 dollars just keeping it running in the last 3 weeks. Later

Nick

[NickBurns]

Thanks LostRacer,

I did locktie the screw in more then a few times. I think the problem is that there is some play in the whole gear that meshes into the diff. I tried something else this time though. I took a screwdriver and stuck it in the diff and pushed out the gear twoards the front of the car. Then I locktied the screwback on so that it was tight and there was no play. It seams to be working better. THe only thing i'm worried about is that the gear meshes to far away from the diff and its going to slip (or strip). I ordered a new wing mount today and also the stainless steel brake set. Anyone esle have any other upgrade ideas for the MBX. The guy at Ace Hobbies said that CVA on the rear end was not really needed. I think my next upgrade is to get a hitech 615 servo to use as my steering and put my hitech 605 as the throttel. Then maybe I will get a new radio. Does anyone know if they make a aluminum center diff mount. My plastic one is striped and I'm guessing that one wouldn't be that expensive. Later guys.

Nick


LostRacer,

Just saw your post on my poll question about LHS trips. I ordered my car from Ace-hobbies. They have been very good and pleasant on the phone. My parts always come quickly. I live in NY and it takes like 6 days to ship UPS ground. My LHS's around didn't have very good kits or RTRs for me to pick from. THe only 1/8th scale buggy I found was an AXIS for like 450+ dollars. It seems like every LHS tries to jam a T-maxx down your neck. The T-maxx looks really cheap to me and would break easy. When I break a part it would be nice if I could just drive over and pick up something, istead I have to wait 3-4 days every time something breaks. Later

Hey check out this place for some great prices on the parts you need. http://greatlakeshobbies.com I got some HITEC HS-5925 DIGITAL HI-SPEED METAL GEAR for 79.99 from them. :)

Nothing like being a Dad on Fathers day http://www.plauder-smilies.de/love/ladysman.gif

[Lost Racer]

Ditto Vetrider..Nothing like being a dad..Nice smily's :) Awsome prices on that site.
Nick plan on racing? If so, go with the 925 or 945. Much faster speed and greater torque.
Or you can go with the digital coreless which are great for re-centering and performance. I have the 5945 and that thing is STRONG!! you might want to try the site that vetrider left us. Outstanding prices. I put CVA's in my rear(my buggy) :D and I like them much better than dogbones, because if I hit something, I don't have to worry about them falling out. I'll keep an eye out for an aluminum spur gear mount for you. Even better, email jr over at ace. I'm sure he can give you any info you need. Good luck! :D :D :D

[Lost Racer]

Ok guys- I did a little seraching for our wing mount friend...I went to http://www.horizonhobby.com and searched through the ofna parts and came up with this part number#OFN30271. The whole wing stay is 30270. I think 30271 may be just the posts on top. price is at $4.99 so it makes sense. If any one would like to verify..That would be great!

Nick- I think I asked you before, not positive, BUT did you loctite your screws yet? That will save you from free spinning diffs(example; you pull full throttle but car goes nowhere.Joint cup is sitting in one place while the diff just spins.) and that bearing from coming out.

For those that run front sway bars, have they helped you? Or would you say it depends on the track? I removed mine because of the rythm section in the track, better independent suspension. Any thoughts?

[morfeeis]

what is the part # to the servo mounts i cant find them

by the way will this be a cool servo i got it off e-bay

http://www.horizonhobby.com/Product.asp?Prod=JRPS4735&Category=D

[Lost Racer]

At that speed and price morfeeis, I'd go with hte hitec. Better performance at the same price. Servo mounts huh..hmmmm
IF they are the same as the ultras use this part number 10273 if not, then try and order a manual. :p Old pic. I'll be taking newer ones soon..

[impulse racer]

hey anybody want to trade one of your buggys for my nxt.

[NickBurns]

Beatnut,

I am still a newbie also but your mixture might be to rich. As you pull the throttel you may be letting to much gas into the engine and its flooding. Try setting the high speed needle 3-4 turns out and then lean it out from there. I'm not sure about the low speed needle i've never ajusted it before.

Nick

[NickBurns]

Nice buggy LostRacer.

Is that a Worlds2. Are those different shocks? I notice the springs are a different color. Thanks

Nick

[Lost Racer]

Thanks Nick. It is a Worlds2. Those are Ofna's hard springs. They're red. Then they have yellow which is softer. I Now have the yellow all the way around for the current track I'm running on. As far as engine tuning goes...I''ll have to check my needle settings when I get home..Someone else will probably beat me to it.

beatnut- Did you get the blue head or red head on there? If you got the blue head, you'll more than likely run a little hot, so try to richen it some. I have a red head if you want it, from a P6. Let me know..Actually its not so red anymore do to my P6 running at 400 degrees..oops. :D Just let me know though and I'll send it to you.

[NickBurns]

LostRacer,

My rear end seams to bottom out real easy, what do you suggest changing. Right now I have different springs on with 2 of the large spacer in the rear. The rear end will kind of like just stay where I set it. If I push it high it will stay there, if I push it low it will stay there. So the bottom end will settle into a low position as soon as it hits the ground. I'm thinking that I need to get different shock oil. Any suggestions?

[Lost Racer]

what weight shock oil are you running?and what color springs?

[morfeeis]

I DID NOT PAY FOR THE SERVO LR IT CAME WITH A CAR I GOT off e-bay awhile ago

i found out one more thing about the buggy i dont have any front brakes.. ok the brake disc is there i am just short of the brake rod

will it kill me not to have front brakes

[impulse racer]

nverminde i jsut got a ofna ultra gt in a trade. looks like i can join this fourm now.

[beatnut]

Hey Lost racer
I got the blue head with my engine, so what is the difference between the blue & red head?

[morfeeis]

impulse racer welcome got any pic's of your ride

beatnut i think they just might be setup different either that r they or made of different metal

[Lost Racer]

Info on my P4. The conrod was fine. I pulled off the backplate andd turned the engine upside down and a little pin fell out. At first I thought it might've been the wrist pin. Looked again and found that it was the little knub off the crankshaft for the pullstart. Oh happy days..I didn't have to dremel it off. It FELL off so now I've just replaced the pullstart with a regular backplate. AND the engine still has excellent compression! Lucky me. Back up engine for next weekend. WOO HOO! Can you tell I'm a little happy http://www.plauder-smilies.de/spin3.gif

[beatnut]

I just got a worlds gt buggy with a P-4 engine with a P-6 piston and sleeve about a month ago in a trade for my T3(the guy didn't send me the instructions for it either) and cant get it to run right. As soon as I pull the trigger it stalls, Ive been trying to tune it for about 2 weeks now. This is my first nitro too. I just want to know the factory settings for the engine and start from there, so if anyone can help me out I would appreciate it, thanks.

[impulse racer]

sorry dont have a digi cam. i will try and find someone who does and get some pics

[impulse racer]

oh by the way does anyone have a setup for the ultra gt for a tight track with a couple of jumps, not real big ones. If you are interested the track is hot rod hobbies.
http://www.hotrodhobbies.com/High/trackBig.jpg

[ 06-21-2001: Message edited by: impulse racer ]

[Lost Racer]

I'm sorry morfeeis..I didn't read into your thread enough :D, Anyway, that servo will do fine. As for the front brakes, they'd help you going into turns and getting traction. When they engage your nose drops and helps your front end gain traction and stability to take turns faster. Can you adjust the caster angle on that car? You may need to do that to make up for no front brake. Adjusting the caster will gain you traction in the turns as well, just slow down before you get to them...If you can, get the brake lever for the front. I don't have an extra of those or else you'd have it.. ;)

beatnut- The red heaad will give you better cooling on that p/s. Thats what it was designed for. If the blue head runs good, don't sweat it.

impule racer- what the surface like on that track? And how is the car setup now?

Here's the track I race on.. http://www.nepthys.com/deltarc/i/tracks/offroad_outdoor_panorama_sm.jpg

[MORFEEIS]

HEY RACER THAT IS WHERE I AM ON MY WAY TO IN A FEW WITH THE GT THE GTLX IS STILL ON THE INJURY LIST TILL I GET A MOTOR

TELL JIMMY HI

[MORFEEIS]

LOST RACER IF THERE IS ANYTHING I CAN DO FOR YOU LETY ME KNOW AND IF IT'S IN MY POWER U GOT IT

[impulse racer]

it is extremely hard packed

[Lost Racer]

Thanks Morfeeis!

Racer-I'm not an expert on setups. But I'll give you my opinion and you can tell me either that I'm a donkey's behind or that I make sense. If you have the stock springs I'd say something between 60-80wt. for shock oil. If you find yourself bottoming out some, then maybe move up to 100wt..And maybe work from there..Do you have other rates of shock springs? Because that will play a part as well.

[NickBurns]

Another problem,

I took my car out for a drive today and it was acting funny. It was running fine but when I hit WOT it would bog down and almost not go at all. Then the engine started making a much higher pitched sound when I reved it and would not move very fast. THe spur gear and the clutch are meshing fine, I think its a clutch problem. Any Ideas? I love my ofna but I am really starting to think about dumping it and getting a mugen, its just non stop problems for me it seams. Later

Nick

[impulse racer]

sorry guys, i did not get a ultra gt. I am about to get a mugen mbx-4xr. It will have a O.S. rz engine.

[Lost Racer]

Thanks for the tease impulse racer ;) :D just kidding..good catch though. have fun with it.

Nick- How many turns is your highend out? If you're bogging at after running a while you're probably overheating. Check for blue smoke when you're running..at all times. How is your take off? sluggish or like a bullet?
Make sure your clutch bell is on good, if it comes loose it will do that. good luck

[NickBurns]

LostRacer,

Take off is fine, the buggy seams to really scream at 3/4 throttel. When I go WOT the engine almost like stops giving power. I see lots of smoke when I accelerate, I'm sure that I am atleast 3 turns out. One thing that I am worried about is that my spit will sizzle away pretty fast. Thanks a lot.

Another question for any of you guys that might be able to answer. I am kind of looking to spend some money and I was thinking about getting an Mugen MBX-4XR Works, it looks very durrable with all the hop-ups and I'm guessing it would require a lot less maintnace then my MBX. I'm not dead set on that buggy but its looks to be an awsome value. All the hop-ups alone over the already nice MBX-4XR total 500 dollars. This might be stupid as there are no 1/8 scale racing around me and I just like to run it around with my roomate. They do have 1/10 sedan racing but that doesn't really look that interesting to me. It would be helpfull if you guys had any comments. Later

Nick

[Lost Racer]

Ok. You said 3/4 is fine but as soon as you hit WOT it starves..you're running the P4? Best thing to do is richen it and see if that helps. You may notice a difference..

The mugen is a great buggy! BUT for bashing its a bit expensive. At least for me. If you planned on racing it eventually, maybe get to learn the ofna first, so you can transfer that knowledge on to the mugen to make it easier. All of that problems you've encountered are typical to a beginner. Or for anyone for that matter. Just be patient with the car. Letting it frustrate :mad: you won't help. Think about it 3-$400 for a bashing buggy thats suppose to be easy to run...Or 5-$600 for an Unassembled buggy thats going to frustrate you even more, cost you more(money and time). :confused: Just my opinion of course...I'd say stay with the ofna and learn its ways first. Then, once you're comfortable, go to the mugen. :D Good luck... :) and may the Ofna Force be with you! ;)

[impulse racer]

Nick are you new to nitro or new to 1/8 buggys? Also nick your problem might be in your fule system. Drain the fuel out and blow into the tank to see how much resistance there is. If you have a fuel filter also check to see if it is clogged. But try to richen it up first.

Lost Racer lol. i cant wait to get my buggy, now I can get some payback at the track. the 1/8 buggy guys would always run over my nxt. No lets see how they like it. :mad:jk Actualy the buggy i am getting is the works version. Why does it break down so much faster than other buggys :confused:

[NickBurns]

This ofna MBX is my first nitro, but I have taken my time with it and made sure that I tried to do things right. I've taken the whole buggy apart a few times to clean it and put in new parts. I guess my biggest problem with the MBX is the drive train. All the little metal peices that connect to the dog bones and CVD's seam to be moving out of the diff cases. In some cases they have melted away some plastic caused by friction. In the rearend the bearing actualy poped out(the one going in to the diff) and the drive shaft was turning at a very wierd angle. Then just yesterday the little pin that holds the drive shaft connecter on in the front end came lose and the frontend lost power(It was just spinning the dogbone like crazy and not turning the diff). I guess these are common problems but when you add these to my others, ruined servo, disk brakes fell apart, screws that hold break levers on fell out, 2 a arms, 1 wing mount, 1 bent rear shock tower, 4-5 stripped plastic screw holes, 2 of my bearings just locked up. Some of this is my own fault becuase I did crash the car once. I guess I shouldn't complain, but compaired to my roomates RC10GT it is a **** of a lot more work. He can just gas his and go most of the time. I do enjoy working on the car but I hate to break a part and then have to wait a week for it to come in the mail.

Do you guys know of a way to setup the suspension so that my car won't flip over on pavement. If I turn my car at anything above half throttel it will flip.

Does anyone use AIM, my username is IanR420.

Later guys.

morfeeis, My job will be taking me out to the Lancaster/Palmdale, CA area from October till about Christmas time. I was working out there in 1995 and 1996 but I was out of the RC hobby then. Are there one or more tracks in the area or will I have to travel down south to the L.A. area to race some good 1/8 buggy tracks?

Thanks

P.S. everybody! I got my 2nd Worlds II (used) in and after I give it complete teardown/cleanup/rebuild it will be ready to get dirty again. :D

[morfeeis]

what do you mean or there tracks out here this whole place is one big dirt track with residents acting as full time turnmarshals lol

no they have not built a real track yet the best i can tell you is that 30 minutes away is a great track called hot rod hobbies great staff great prices (when you get to know him they get even better) and they always have time to help you just call first

I'm here, I striped a servo in my MBX so I havn't had a chance to run my car in the last few days. The track I was planning on going to got shut down by the town or something. I wish someone had a 1/8 scale track in upstate NY. Later.

Hey Nickburns dont worry we will get the track problem fix.We will be running the races its a free country and jason's land.
We wiil get it resolved. :)

Hey guys, I just picked a up a Picco Comp enginge frome ace hobbies. $189.. Its looks like a really good engine. Boost bottle already installed. I can't wait to get home and break it in!! Does anyone else have one, or has had one before? Any advice?

[elscotto80]

Hey, don't have one of those engines but I hear they scream, good luck with it. Now I need some advice. What is a good reciver pack and charger to use for my GT LX? I got one but the charger for it is 50, i'm not spending that much. Thanks guys!

[Lost Racer]

Very kool NU-B. :D j/k.
You're going to love that buggy. Lots of fun. Man, I sound like a salesman! A must upgrade as I'm sure you read is the steel spur gear.

elsco- I bought a generic pack on ebay for $20 5-cell nicad 1000mah. Works great..then Ibought a charger from ace hobbies. I think it was like $14 or something..I'm not sure I don't remember. I need to get a peak charger to do my packs though..Much better. Thanks on the engine, I'll be putting 2 more tanks through it tonight and 2 more tomorrow. I'll be racing it on saturday..So I have to get it broken in.

[NickBurns]

Good choice NUBlackshirts,

The first thing I would do is upgrade the steering servo. The stock one is a peice of trash. It will handle 100% better with a nice high torque servo. Make sure you get a good one with metal gears or it will strip out. The only other thing I would this is to ajust the breaking linkage becuase when I got mine the brakes sucked until I tweaked it a little. With the brakes setup right it will almost leave rubber on the pavement. Later

Nick

[NUBlackshirts]

Already took care of the steering servo, NickBurns. I replaced it with a Hitec HS-645MG. Just running around my backyard I could tell a big difference. I'm still running the stock servo for the throttle/brake. It seems to work ok for now. I will do the brake adjustments once I get to the track this weekend.

[morfeeis]

lost race i think you got the same pack as me i think it is a ofna pack

[NUBlackshirts]

Hello all. After reading all of your posts in this Ofna forum, I decided to get an Ultra GT LX. This is my first nitro vehicle. I have raced electric RC since 1987, both on and off road. I stopped racing a couple of years ago and sold all my RC stuff. However, a friend of mine got a Mugen 1/8 and as soon as I saw it run, I knew I had to get back into RC again. I got my GT LX running last night and I am very happy with it's speed. This weekend I am going to take it to the local track and get some practice/tuning time in. Will let you know how it goes. Thanks for everyone's info on these vehicles as I have already used a few of the tips that I have found here. :p

[Lost Racer]

Are yours nicad ir NiMh? Mine are nicad. I have to get some NiMh ones. And a peak charger to do them.

[morfeeis]

they or 1000mah NiMH Receiver Pack a person named jennybee7 sold them to me :D

[Lost Racer]

hey cool! me too! Uh oh..I guess I'm charging them wrong..or my charger does both. hmm. Oh well. I went to put another tank through my Picco Comp last night and my starter box battery died! :( so its been charging since 9:45pm last night..When I get home tonight I'm gonna try to do a couple more tanks. I have racing this weekend so I have to quicken up this break in...

[Jonathan 210]

Hi i just bought a ULTRA GT LX RTR from towerhobbies. Only $329 !!! I cant wait to get it! Oh and this post is HUGE, maybe we should make a new one. It is to big for me to read everything. I need to know where to buy stock parts for my ULTRA cheap. I know towerhobbies doesnt have any. Oh and what are some good first upgrades? Can you guys please post your pictures of your paint jobs on a 1/8th scale buggy so I can get some ideas. I never painted a 1/8th scale body before. In fact i only painted one body my whole life and that was one solid color. But I guess one solid color isnt too bad. Im cheap when it comes to a paint job.Thanks.

[morfeeis]

I'll tell you just like i have seen racer tell a lot of people.. before you start thinking about hop-up parts you should learn how to handle all the power that you have.. i not sure but the gtlx rtr comes with a p4-ps that is 1.5 hp's learn to control that then start getting hop-up's as far as stock parts go you can get them from

http://www.ace-hobbies.com/ or

www.ace-hobbies.com (http://www.ace-hobbies.com) has very good prices on parts. They are very pleasant on the phone and ship things out as soon as possible. As far as hop-ups, I would get a steel main gear and a better steering servo. I might also get CVA's in the front end. Other then that its pretty well setup. One other thing is maybe a stainless steel brake set, my fiber brakes broke off. The only problem with that is that the stock throttel servo is not powerfull enough to make my steel breakes work. Good Luck.

Question for the rest of you guys. I have the option of getting a New in box Lynx Hitech 3D for 132 dollars shipped. What do you think? Later

Nick

[morfeeis]

i think you should get it before i find out where and get it before you lol

thats a great deal dont pass it up

[NickBurns]

Hey guys,

I posted this in the engine forum, but I also wanted to know what you guys though.

...

Right now I have an Ofna Force p4 and don't have any problems with it. It will idle fine and seems to have ok power. These are the engines that I am considering. This will be going in either a mugen xr or kyosho 7.5.

Ofna Force p8, at 2.5hp and only 180 bucks it looks like a good deal? Any opinions?

RB 1003-S7, A little less power at 2.2hp but I've herd really good things about RB engines. Its also about 30 dollars more.

Picco G1B Buggy, Same hp as the RB, and also the same price. This engine looks cooler though.

OS 21 RG, Cheaper engine but a lot of people seam to like OS.

THanks for your help.

Nick

[NUBlackshirts]

Well, I took the GT LX to the track for some testing yesterday. I could not get the car to run right. It ran fine last Wednesday evening when I was getting it broken in. But I think it was just WAAYYY too hot yesterday. I think I left 5 layers of skin on my plug wrench! I could get it started and it would idle fine, but it would die if I tried running it around. It felt like it was about 120 degrees outside, so I don't blame the car for not wanting to run. I will try again later this week. Will wait until it cools down in the evening. :cool:

[Lost Racer]

Loooooonggggggggg Weekend of racing! I had a blast! Great to see this thread lives! :D

Ok now down to the nitty gritty:
Jonathan210- Morfeeis and NickBurns are right about what you need for that buggy. The P4 is a GREAT engine for starting with. If you take care of it, it will last you a long time. As far as finding parts; Ace is great; I haven't tried discountrc yet; AND last but definately not least http://www.nitrohouse.com . If nobody else has the part they ALMOST always do. Their number is on the website. Good Luck and learn to setup and control your buggy befor you go for the power..Trust me I learned the expensive way.

Morfeeis- The P4 is great, and will run like its indestructable. However I think The OS RG takes it on this one. My friend has the OS and swears by it. But either way it would be a great choice. I don't think the OS has the PS though..You can get a P4 w/o a PS also. Its about $30 cheaper.

NickBurns- Don't do the P8! I was going to get one last week, until I talk to JR at ace. If you wanna stay in that price range. Go with the Ofna\Picco Comp. Much better power and cooling. Built in boost bottle and is only $10 more. This engine is ballistic! I just started to lean it a little on saturday night. I bought it on wednesday. At ace for $189. Talking to JR he says its pretty **** close to an RZ. Don't look at the hp because it doesn't mean squat!(To a point) You haveto realize that HP is being produced when you're running that engine at a set RPM for a set amount of time ie:full throttle. When racing you're not usually sitting on the throttle to get to that RPM. Ok, RB great engines!!!! I had the Europa and that engine flew!!! But if you do get an RB make sure to buy the extra strength rod. Whew! Running out of breath. Did I miss anything? Oh yeah,

NUBlackshirts- In heat like that richen it up. It'll be ok.

I raced this weekend very rich on saturday for qualifiers. then on Sunday for mains I had it leaned out and didn't finish the race because I fried my receiver. :eek: :mad: :(

[NUBlackshirts]

Lost Racer,

I figured that was what needed to be done, but it was just too hot to stay out there and mess with it. :)

[Lost Racer]

I understand. I've never been in 120 degree weather before. But stockton stays in the 100's for multiple days. And it does get uncomfortable. Even in the shade. Yeah just richen the engine up, a little at a time and you'll do fine. The funny thing is even in cold weather you need to richen because of the denser air. Have fun!

[vetrider]

Welcome aboard NUBlackshirts. I drove through Ft. Huachuca on my way to Yuma, AZ several times over the last 12 years or so. Get's pretty darn HOT there too! :D

And yeah, on what Lost Racer said on tuning.
:cool:

[morfeeis]

my brother said it's 115 on a good day and 120 is kind of hot in AZ :D :D :cool:

[machinehead]

What weights diff fluid are you guys running (front center and rear)? My rear wheels keep kicking out like crazy.

[morfeeis]

IF YOU LOOK A FEW PAGES BACK THERE WHERE A FEW POST ABOUT THAT :eek:

[very low budget racer]

is the ultra GT LX raceable at the club level? the only downfall I see to it is no front kick up, but its the only buggy in that price range I can afford.

[BadReligion]

Hello. Has anyone tried the new MBX R2 yet? I was thinking about getting one for my first 8th scale. Is the worlds 2 better? Thanks guys

[vetrider]

The Worlds II is considered to be the better buggy of the two, but driving and setup skill will overcome most differences. You can add the rear pivot ball suspention from the MBX to the Worlds II and have the best of both. ;)

Vet's Site (http://vet_rider.homestead.com/)

[morfeeis]

very low budget racer

the gtlx is a good buggy to start with. Witha good driver it could be a nice buugy but if you want to race i would go for the worlds 1 or 2 like vetrider said :D :D

[BadReligion]

Anyone know if the Worlds 2 and MBX R2 accept the OS 21RG without modification? I dont want the pull starter one. Thanks

[CBlakeNS]

With pull start mounts yes it will work! Good luck!

[BadReligion]

So I have to get the PS mounts to fit the OS without a pull starter? Oh and 1 more thing. Is the clutch a regular one or does it need the pilot shaft version? Thank you!

HI i have a worlds gt and i went to change the shoke oil and put 40wt in and now my shocks are softer than ever and was wondering if 1/8 buggies shocks take a specific type of shock oil andi saw a vented fly wheel and wanted to know if i could us it on my P4. Thanks Curtisnullnull null

[Lost Racer]

ohh the holiday was long. I stripped my Torsen spur gear yesterday. Is there no justice?!!!
BadReligion- My friend is running an OS RG in his Ofna HODR Non PS. ANd think he's using the non ps engine mounts. The pull start engine mounts raises your engine a bit more above the buggy. So the pullstart can clear. Not sure on the shaft though.

bond2000- I use mugen oil in my shocks. There is no ONE type you have to use. Just be consistent. The viscosities aren't always comparable between manufacturers.
As fas as the vented flywheel..Anyone have info on that? I was wondering that one also. :D

Hope this helps.

Racer_X- Thanks for the part number..I was looking for those as well.

Has anyone run there buggy on the off-road track in antioch because I race on-road there and am getting into off-road too.I am getting a ofna worlds 2 or something like that.nitrocam3 :D

[Lost Racer]

I usually do. Did you go to the duel? It was a lot of fun. Great track to run on..When its watered down. I run a worlds 2 there. Its very competative.

[bond2000]

Thanks for the help. and i was thinking that we should start a internet club for every body who has a ofna buggy or truck and that way it could be a world wide club. and i have one more small question i ran my buggy yesterday and when i gave it full throttle and let off it died soon after it started to slow :) :p :D

[Lost Racer]

Was it sputtoring or did it sound dry?
If sputtoring then you're too rich. If it sounded dry, then you overheating and are too lean. What engine is it? P4? Or have you updated to another one? Are you still breaking it in? How many turns out are you in? Are you weraing any socks? Did you brush your teeth this morning? OOPS! a little off topic there. :D Well, you get the picture. what do you have your needle settings at?

[bond2000]

well it did neither it would die a little after it slowed it just would stop and my setings ar 3 1/2 High needle and flush Low needle. the engine is the P4

[Lost Racer]

Its already broken in correct? How does it idle? And have you changed the plug since break in?

How will a MBX r2 compare with a Mugen at a club track with a good engine? is the kick up really that important?

[dregnier]

I've been flying planes, helis, and 1/10 scale trucks for a while. I went to a nice track in Houston last week and couldn't believe how fast and smooth these things are. I decided I just had to have one. I got the MBX R2 w/ a P4 .21 engine. Is this a good combo. From what I read it seems like it's built fairly strong except for maybe the diffs. What do you guys think

[Lost Racer]

I read that the kickup isn't really that important unless there's a samll rhythm section where the nose is constantly moving up and down. And with the R2 you have the ability to fine tune your rear now as well as the front.

bond2000,

That would be cool to have sort GOOD website that delt with ofna buggies or even 8th scale. It could have setup tips for different tracks, a messageboard and such. There is that one good website called twf8.com or something wierd like that. A lot of the info on there is dated and I think the webmaster is not american. A lot of rc websites don't have very much content, just a lot of pictures and message boards. If anyone was interested I could help out, I'm a senior computer science student. I could also run a website off of our schools network on one of my old computers (We have an Oc3 connection).

Hey lost racer do you race on-road there?I also plan to race off-road there as well, the off-road track looks pretty sweet and looks perfect for 1/8th but I heard that its really kind of tight for the 1/8th and just perfect for the 1/10th what do you think?My frien Kurt Bowers races 1/10 off-road there from time to time and also races on-road with me and my other friend Brian Lamatina were a pretty fun group.nitrocam3 :D

[bond2000]

it is broken in and idles slightly fast than most nitros i've been around. oh and i was
wondering would the W2 body fit mine. we should start that club. and i did change it to a A5

bond2000,

The stock pistons that come with the Ofna kits have fairly large holes and are not large enoungh in diameter to keep oil from passing around the piston. That is why your suspension seems like there is no dampening. You will need new pistons. Ofna makes a teflon set part # 32235. You get 8 (2 hole) teflon pistons. Thet fit perfect and allow no oil to escape around the piston. However the holes are to small. I have drilled mine out. One set to 1.3mm and the other to 1.4mm Currently I am using the 1.4mm with 60wt oil and red springs. Its a little on the firm side but provides good responce and dampening for large jumps. Nitrohouse (800-928-0304) has these pistons and most Ofna parts available

Hope this helps...... ;)

if we got alot of people we could have a page for 1/8 buggies over at my site :cool:

[Lost Racer]

nitrocam3- I ran onroad out there once a couple weeks ago. My Prime 12 caught a pipe and ripped the front wheel hub right off. The offroad is great for the 1/10th scale. The 1/8th are a blast also. OFr the buggies you jst have to be more technical rather than gung ho. Thats it.

bond2000- When you go WOT from a stand still, does it bog then go, or does it just go?

bond2000- turn brass screw in about 1/8th turn and keep trying. your highend sounds good, so i think your lowend may be rich. And for you veterans and normal engine tuners, for what ever reason, ofna has put their lowend needle the opposite side of the slide. Normally the needle is found within the boot. But on the P4 and P6 its on the outerside. On my P6 I have the screw 2 turns out from close. Try that. If you're unsure, count how many turns in it goes s oyou can put it back to what you had before.

[Lost Racer]

Ok. Just ordered a new spur from Ace Hobbies. They said 3-4 :eek: days before I get it. I need it by saturday!! what am I gonna do?!?!?! ugh!

[very low budget racer]

I plan on ordering my MBX R2 once i sell my GT from ace, they can ship me stuff COD (no other place will).

[bond2000]

LOST do you mean the high or low needle? :)
AND WILL THE WORLDS 2 BODY FIT MY WORLDS GT BUGGY? :o
