OFNA 1/8 Buggys v2.0

[-=ADA$=-]

i want my buggy :(:(:(:(:( :(

[Crashbot2001]

ADA$.. What are you getting and when?

[Uptonw567]

hey do u know if the bevel gear set is 4mm for the ofna ultra worlds
Landan

[-=ADA$=-]

im getting MBX R2, and when well i hope as soon as possible, but seriously, i dont have credit card for my own, so i use my fathers, and i have to wait untill the bank will bill his card for my previous purchase, ( well thats what he sais) but i want it now, and than probably ofna delta force :):)

[Crashbot2001]

Hey guys, got my kit in.. It is SWEEEEET!

A couple of things I noted.

It's big(I'm used to my XXXNT and Rustler)

It's heavy(ditto)

The Diffs already seem to have shims in them, and everything fits very nicely.. no oil though..

No threadlock was used anywhere...that's old news

Not impressed with the screws they used.. Phillips head? $10 at the hardware store will fix that...

It's Big!

Gonna be a little while before I can get the cash for an engine.

Anyone have a .21 sitting around collecting dust? Even if it's beat up. I'll pay shipping and then send it back to you in a month or so when I get my new mill, cleaned up and tuned!

[RCNitrodude]

Yes, the diff bevel gears for the Worlds 2 are 4mm, the part number for the set is A-77, the shaft set is A-77A, and the cross pin is A-87B. These are the new Ofna stock numbers.

[Vmax911]

Crash

That's the same thing I though when I get my 1st 1/8 buggy. It's big, it's heavy, and look at the diameter of those tires! Just puts a grin on your face. Hope you get it running soon!

[-=ADA$=-]

i believe you crash, but i want to feel it myself :(, also why are you wanting to change the screws, and what oil is missing?? diff shock, or else??, if i cant get my buggy now i just want to get parts for it now

[Crashbot2001]

I have a question for you guys on the diff oils..

I understand I want the thickest in the center, medium in the front, and the thinnest in the rear. I even understand why. What I don't understand is this:

Some folks go with 10,000/7,000/5,000

Some go with 10,000/5,000/3,000

Some go with 7,000/5,000/3,000

And some 7,000/5,000/1,000

What is this effecting and by how much? What are the pros and cons of the higher number set-up? Same for the lower end?

If you were brand new at this again, and were going to be running on tracks you've never run a buggy on before, what would you start with? Is there a set-up for diff lubes that you would recommend as a starting point? And once you did, what would you look for to indicate you might need to go higher and/or lower on one or more of the diffs?

Thanks!

[-=ADA$=-]

any advices on what should i get befor i get buggy, screws, oil, something else, and does it come with header and tunned pipe?? how do you like it??

[Crashbot2001]

You'll need threadlock, Superglue, Diff oil(shock oil too if you wanna mess with the weight)

ADA$

Other than that, it's pretty complete. Header, pipe, coupler, header gasket, spring, pipe hangar, throttle and brake linkages, etc, all included. Even an antenna tube. No radio, reciever, or servos of course. And no Engine! lol

You alos might wanna look into a brake pad upgrade. I dunno what's available for it, but the stcok ones are kinds cheesy looking. They look like cork but feel a bit firmer.. I really need to find a place to buy Carbon Fiber in Small sheets. 12"x12" would be fine.

Also might wanna get an aluminum servo horn for the steering.

I do plan to upgrade some of the screws, but I dunno the sizes yet.. lol

EVERYONE....

Does anyone one if Carbon Fiber aftermarket towers and radio tray are available for the MBX R2? I might want to try some out.

Thanks!

[-=ADA$=-]

thanks alot, ill get is as quick as ill be able to walk :) have fun with your buggy, and hope youll get your engine soon

[Uptonw567]

I just got a reallly reealllly good steering servo it has 220 oz torqe with 4.8 volts its a hitech, so that should help out alot since my servo i have on it right now only has like 80 or 90 oz of torqe i will be getting pics soon
Landan

[-=ADA$=-]

is it something from 6** series?? so how much is @ 6v
*edit: what is the difference between mbx r2 and plus, and crush, maybe aluminum shock towers, or something like that, i found it on ofna site

[Crashbot2001]

ADA$ The towers came aluminum with the kit

[-=ADA$=-]

thats cool,

[camillerim]

hey guys i got an Ofna speed 9.5 standard version (the one that comes with the exhaust system, but without the raido or engine)
and i need help to what engine i should get? im not gonna be racing straight away and i want to get a pull start! what pull start engine to u guys suggest i get?? sorri for the length but i need help thanx

[switchblade_327]

Hey guys, I'm new here so, but I plan on coming in on a regular basis, so anyway, I have a ?, I have an ofna ultra-gt rtr with the stock engine (not sure about the specs) and I'm having some break in probs, I know you're supposed to run really rich, and that's what I'm doing, but the engine still runs hot, I ran it a few days ago and the temp was around 300-370 pretty hot, but I don't know why it's getting so hot, there's a decent smoke trail coming from the pipe, and I figure smoke is a good thing, so I left it, and it still ran hot, so if you guys have any tip/suggestions that would help a ton, thanks

oh yeah, and I'm using 20% byrons nitro fuel, so if that helps any.

thanks again.


gabe

[switchblade_327]

Hey Crash, I have an ofna hyper .21 w/pullstart that you could use, it hasn't been broken in yet, it's still in the box, maybe you could take care of the break in for me? :D


ps: I'll pay shipping for the favor :)


gabe

[coyote660]

arizona huh?...that's half your problem...check your temp guage..that engine would probably shut down before it hit 370.

[switchblade_327]

yeah, it is pretty hot here, and I'll check the temp gage, it's a traxxas on-board, so I dunno if it's cheapy or not, and I ran it at night, when it's a lil cooler, but we'll see, this is actually my first buggy so, yanno, new terrain, bigger engines, all of that, but I also read from the ofna site that the .21's are supposed to run cooler than the smaller engines (don't ask me how or why, cause I don't know) they put the .21 temp at 200, which to me seems kinda odd, bein a bigger engine and all, but, I also heard that ofnas customer service is shabby, so I'm lost on that issue. now back to MY engine, what could I do to cool it down? would changing the nitro content in the fuel help at all? I was thinking around 15%, and I'm not gonna race it so, I don't need to be pushin it to the limit, I wanna get all I can from this engine without shootin it to hell.

engines I've shot to hell:

4 trx .15's
1 duratrax torq .16

maybe I should take the hint and switch to electrics? :confused:

thanks again.


gabe

[-=ADA$=-]

i think that maybe higher oil content, and i dont think that there is 1/8 electric 4wd,

[coyote660]

no,no,no...batteries are for flashlights;) just fatten it up a bit and see what happens...i run my ofnas at 220 to 250...no problems.

[-=ADA$=-]

well and whats with that diff greas, what would be best setup,????

[switchblade_327]

I think I might have discovered the problem, I was lookin over the engine, and the throttle/brake links, and I noticed that the brake was WAYY too tight, which would clear up why it stops almost immediately after I let off the throttle, unless it's supposed to do that, I dunno, help me out guys :(

thanks.


gabe

[-=ADA$=-]

there should be some kind of stoppers that hold the brake, just slide them opposite of brake.

[Crashbot2001]

Gabe, you have a private message

About your heating problem. It could very well be the brakes. You do not want the buggy to stop as soon as you let off the gas. You need to adjust the brake linkages so that you have little or no (some people like a little bit of brake drag)brake applied when you release the throttle. Note: do not attempt to do this by using the throttle trim on your radio. This would cause the engine to rev pretty high, even with no throttle applied. It will also cause the engine to drop in RPMS when the brake is applied unless you also adjust the idle screw. Best bet is to pull out the hex wrenches and adjust the linkage manually.

The added resistance could definately be the reason your engine is running so hot. Kinda like running in very tall grass. Or driving your real car with the parking brake on.

Let us know what you find out

Good Luck

Crash

[-=ADA$=-]

crash, i have question, is header and tunned pipe included, also the header is it for pull start?? cause i was thinking about getting some cheap engine like duratrax torq or megatech, it would be cheap, and i dont want performance engine but just engine, when ill order my buggy, i would like to order engine too


*edit: or i found that hyper .21 would be good as well its pull start, 2hp and long stroke so it has great torq

*edit1: is the kit equiped with flywheel, and clutch for pilot shaft?? thanks

[Crashbot2001]

ADA$

Yes, the header and tuned pipe come with it, as well as the coupler to join the two, the header gasket and mounting spring. All you need to add is an Engine.

As for the header being compatible with a pull start, I really don't know. I haven't looked at it too closely yet(the header). I will wehn I get home from work today. I sure hope it is! Being a stock header, It probably is.

Crash

[-=ADA$=-]

i looked at tower at hyper .21 and it has header for it so if i would buy this engine i would have two headers, cool :) thanks for help Crash

[Crashbot2001]

ADA$, yep, Flywheel, clutch shoes, spring, and Clutch bell are all included. Not sure about a bevel cone or clutch nut. I'll have to look for that as well when I get home. I'll let you know

Crash

[-=ADA$=-]

i believe its with the kit, cause it is always used, so i think there should not be prolem with this

[Crashbot2001]

Hey guys, I'm sure most of you that have them already know this, but I thought it was good info to pass on.

I just read an article about an 11 year old kid that was killed by an RC plane. Imagine, you're out with your son trying to get him interested in a hobby and he ends up getting injured.

The operator of the plane had a PCM radio and had never programmed it. He switched his radio to PCM mode, unaware that he had activated the Failsafe device by doing so. This was not the only cause, but it did contribute to the accident.

If your radio is operating on PCM mode, the failsafe mechanism IS operating. Most of these built in failsafes have two modes: Hold and Preset. Hold will maintain the last setting recieved before signal interuption. Preset will move the servo to a preset setting, dictated by the user of the radio.

Unfortunately, most PCM radios come pre-set to the Hold setting. Unless you change it and adjust the pre-set to idle or brake, the reciever will hold the servo in the last known position. In the case I referenced, this caused the engine to hold it's throttle setting once the signal was lost.

The same thing could happen with an RC. Some of these things(particularly the buggies) weigh a lot. Take the time to set your equipment up correctly before you use it.

I believe a recommendation was made to the manufacturers to clarify operating manuals, change the factory default, and a few other things in order to help prevent this sort of trajedy

[-=ADA$=-]

that sucks big time, i always try to be carfull, and not to ride when anybody is too close

[Dnmeistr]

Due to this forum I decided to get a Hyper 7, I hope I'm not making the wrong decision. I have a xxxnt but I am going to sell it for the Hyper :) It was 439.95 at Stormer only a little more than a MBX in either kit form or rtr, if I wasn't starting from scratch I probably would of bought the MBX kit. From what I have read the buggy doesn't need any hop ups out of the box accept for maybe some stiffer springs and gear oil to replace the grease, is that right. I would like to put some truggy tires on it I don't want Maxx size but something in between anybody know of any that fits or maybe I need to move up in wheel size. I have masher 2k's on my Losi and really like the way it handled and jumped plus they were great in the grass. I am sure I will have more questions once my buggy arrives. Thanks.

Dnmeistr

[coyote660]

dnmeistr...up grade the steering servo...the plastic gears will fry immediately and 50 oz doesn't get it either....that's stock on the rtr.

[Dnmeistr]

I forgot about the servo :) You think a Jr z550 will be able to handle the power, I don't want to spend a $100 on a servo something less than $40.

On the o-ring pistons tower lists two by Ofna which one is correct.

Ok guiys, ran into my first snafu with my MBX kit. I was trying to assemble the clutch shoes and flywheel assemble. All the clutches I'm used to use a sprin "loop" configuration where the spring just wraps around the outside in the groove. These are quite different.

Seems each shoe has it's own spring(all 3 of them!)

I figure the longer piece of the spring fits in the groove on the outside of the shoe, and the loop in the spring fits onto the flywheel pin. This leave the short "tag" end of the spring sticking in towards the center of the flywheel. Fine

I can visualize how, once the clutch nut is screwed onto the crank shaft, the spring "tag end" might be forced to the side of it, causing the spring to hold the shoe in, as it should, but how do I go about getting this tag end into position? Much less all three at once!

There must be a trick to this

Maybe I have them wrong?

The manual shoes how they are placed on the shoes(sort of) but that's it! Not much help

Thanks in advance

[Vmax911]

From what I can tell you've got the right idea. Use a small screwdriver to put the "tag" part of the spring on the appropriate side of the clutch nut shaft. Use the screw driver to guied the spring into the groove as you push the shoe fully onto the post. For the second and third shoes you may have to lift the installed shoes up a little bit to get the spring into position. It's not too bad once you've done it a few times. :D

[Dnmeistr]

Just received my Hyper 7 from Stormerhobbies, first impressions is of course it is big, wheel and tires are nice size. Pulled it out of the box and set it on the table and the chassi sits about 3/16" off the table, so much for the big tires LOL. I added all the shock clips included, that's 5 on each shock to raise the chassi off the ground to where the arms are fully extended. I thought these had more ground clearance, my XXX-NT has more clearance. Speaking of Losi there RTR kits are much nicer more attention to detail, the edges on the Hyper body are rough and doesn't even have the rear body post cut out And for a RTR you would think they would include a $4 glow plug. The linkages were all out of whack, just had to recenter the servo horns, and I added springs from a couple pens I salvaged to go between the brake levers and servo arm to keep the stopper tight against the brake lever. Otherwise as the brake rods would slide through the brake levers they would sometimes get caught up and prevent the servo from going back to idle. Other than that I am happy with the car, LOL. Will be breaking the motor in later today.

i have ordered mbx more than week ago, and hoped it to arrive in close future, but no, when ive returned from my grandma's house i noticed that there is new site of the shop ( i wont say what shop it is) and even there is very nice customer support, the order hasnt shipped till today, so i wanted to know if they billed my fathers credit card, and they didnt rospond to this question yet, so probably ill have to wait for my buggy till next month, that suck big time, i would have it next week, but one thing makes me more happy, finally my new MX-3 arrived.

[Crashbot2001]

Are you talking about the Airtronics MX-3? If so, where did you get it? How do you like it?

[-=ADA$=-]

yes its airtronics mx-3, i got it from stormer, but now they dont have it i think but check tower i saw it today, and i love it before i had hitec lynx am, and it had no functions, and mx-3 has everything i need, endpoint, ARC, and i like the way it fits my hand, also the reciever is really tiny, its just great, and very cheap, but i think that 3-channel switch will be fragile its plastic, and looks very delicate, but maybe im wrong, but i love it, and recomend it to everybody, it looks like blazer, but its great, well i dont have warranty because i live outside of US but i will be cautius, also i was wrong about shop, too quick i got respons, and ill order mbx right now.

[Crashbot2001]

I wish I had known about the MX-3 before I bought my XR-2!! lol

Can't wait to see one in person.

[-=ADA$=-]

i think that there are only 2 disadvantages of xr2 ( comparing to mx-3) two model memory, and that its AM, but i have to admitt that its great AM, i believe best there is, and how is you MBX, does it have to be assembled, or is it like prebuilt?? i would prefer full kit, but couldnt find one, tell me how do you like it, i will order it probably next few minutes :)

[Dnmeistr]

I really like the XR2 that came with my NT, the batteries last a good long time, and the range is pretty good too.

Here are some pics of my Hyper 7 and xxx-nt.

[Dnmeistr]

Got a chance to run the Hyper 7 today and wow this car is sweet and fast, built a small jump jumping onto the grass and this car jumps way better than my xxx-nt. Took some tumbles and came away unscathed, can't say that about my xxx-nt seemed like every time I brought that out I was breaking something, though spare parts are real cheap to buy. Only problems I had were during break-in, the motor developed a leak in the backplate after the 3rd tank. I sealed the backplate and the engine is running fine now. If this is such a common problem I don't understand why Ofna doesn't do something about it.

Dnmeistr

[-=ADA$=-]

i wont be able to run H7 but im waiting mbx it should arrive in monday next week

[Crashbot2001]

hey guys, I've got an Ofna MBX R2 and I've been looking around at NiMH battery packs. Anyone know of a cell configuration that fits well inside the radio box with the receiver and switch?


Edit: Here's a beauty shot of my new paint scheme. Very quick and easy.. lol

http://www.imagestation.com/picture/sraid29/p3ee732a1a923cb843e8bf007d9438e2d/fd5a3b9f.jpg

Thanks!

Crash

[-=ADA$=-]

i think that most popular is hump pack 2 cells on top 3 on the bottom, what grease configuration have you choose for your buggy??

[Crashbot2001]

Thanks, I'll borrow one from some one and see how it fits.


I still have not decided on the diff lube. I'm thinking 7k center, 5k front, 3k rear. Also, very hard to find someone who has it in stock!

[-=ADA$=-]

man i like that very much, and what engine is it?? now im waiting for buggy and for money from insurace ill buy my engine for it , well ill have to add somethig becasue its only $100 or about, but always something,
*edit: forgot to ask is the body with the kit or have you bought it yourself??

[Crashbot2001]

Thanks, that's the body that came with the kit. I wanted to keep it basic so I just used spary cans and some masking tape to tape the windows. The Engine I picked up off of e-bay used. It's an OS RX .21 Don;t know the specs on it but it has good power and seems to be holding a tune well. Still saving for my RB Concept S7 Europa, though I hear everyone is out of stock on them anyway.

Anyone looked at getting parts yet? I haven't seen anyplace on-line for buying parts for the Ofna MBX R2. I haven't broken anything yet, but I'm sure I will. I would like to get some different tires on some extra rims so I can see what works at my track, but I dunno where to get the rims and tires either!! Thanks for the help

[-=ADA$=-]

thats great that body is with the kit, also cool that you have engine, i think ill get hyper .21, or if ill have more cash i would get delta force, but now waiting for buggy to arrive try www.ace-hobbies.com , and look at worlds parts, i read they fit

[-=ADA$=-]

i checked at USPS.com and found that my buggy is already in Poland, so probably it will be week now.

[OmegaTrac]

Hey guys,
I might be getting an OFNA Worlds 2. Is this a good buggy? I am only going to bash and race a little. SHould it work well for me? Any hopups for it? Hows it handle?

[-=ADA$=-]

i read @ TWF8 that its great buggy, and it can handle the abuse of race

[eman88]

Crashbot2001-try an ofna brick pack. i have a brick pack, switch, and stock reciever from blazer sport radio(the one that came with my buggy)
i have plenty of room in my reciever box with the brick pack. its 30 or 35 bucks at stormer hobbies and is 1000mah nimh

[-=ADA$=-]

i read about this, its the pack made of i think 5 or 6 flat cells, am i right??

[Crashbot2001]

E-mann, thanks.

I usually buy my battery packs from www.onlybatterypacks.com

They have everything you could think of and they're half the price of the trinity packs and such, plus you can specify any connector type you like. They even have packs sepcifically designed for different RCs. I just got one for my XXXNT and it fits nice and snug.

I have the specs on all their packs, dimensions, etc. I just need to take the time and measure the interior of my reciever box to see what will fit.

[-=ADA$=-]

then gimme what youve choose, ill probably get same, :D and i have one more question, can i use some other greas, cause i cant find shop here that would have any diff greas

[Crashbot2001]

lol, everyone is out of diff lube here too! My LHS is ordering some for me from General Silicones. I decided on 7,000/5,000/3,000

[-=ADA$=-]

my hobby shop have phoned to some kind of central that they order everything from, and they dont have greas at all, im affraid ill end up with normal greas in all three diffs, or ill order diff greas with engine, but it will be next month or two months, man i want that buggy running, :D:D:D

[nitro gabe]

I have a 1/8 scale ofna bugie and the motor isn,t runing write
Igive it fullthrottle and it start,s rev up then start to hessitate but it no the carb setting bin over it 100 of times can't figure out why
star's fine won't ope up throttle all the way but just not getting to full rpm could stone filllter in tank be faulty :confused:

[-=ADA$=-]

i think its too rich, but check your linkage, or maybe air leak, is the idle stabile??

[-=ADA$=-]

man i got the kit finally, im gone say what everybody said, its so huge, the wheels, and everything, i wont assemble it today cause i want to get greas first, but i want to know should i cut the foams so they will fit the tires or leave them as the are, and any other tips how to build it will be greatly appreciated. man i love it already

[Crashbot2001]

ADA, I put the foams in withoug modifying anything.

Glad to hear you got it in safe and sound. Have fun!

Don't forget to add thread lock to all the metal to metal screws. They didn't do it at the factory, even though both manuals(mine came with two, slightly different from each other) indicate to use it on certain screws and nuts.

[coyote660]

hey gabe....too lean.

[Crashbot2001]

ADA, forgot to mention, the diffs come with some grease in them, so you can run before you get yours in.. looks like lard, but I guess it does it's job.. ;p

[Crashbot2001]

Hey ADA, how's the Kit coming?

[-=ADA$=-]

i was out for few days, and i have put the buggy together, i checked, and the diffs have grease, so i wont have to buy any, but wait and get the config i want, also ill probably get engine next month (i have to get money) but i love it, its so big, i want to say that i hate glueing tires to rims, i glued one, and almost glued myself to it, but ill probably do it tommorow, when ill be more patient, also i got two manuals, one for Ultra GT and one for MBX R2, as i looked at both i have Ofna Ultra MBX GT R2 cause it has parts of both, well i hope to get engine soon, and check the performace, but i love it already, i noticed that suspension is very soft, so i added two pre-loads the biggest, and the smaller one, so now it dont squeeze the shocks when standing. also i noticed the manual sais plastic radio tray posts, and there are alu's :):)

ok thanks for all help, ill get back tommorow.

[Allen T]

Guys...

I've seen some posts about transforming these buggies into what I'd call "Monster buggies". I also saw the latest R/C Nitro mag, and the Kyosho buggy with the Proline ST body looked pretty cool.....

Does anyone know if there are any body posts that will mount to the stock MBX shock towers? I'm not racing, just bashin' around.

The MBX looks SICK with the Dominator tires/wheels on it!!!

Coyote, thanks again for the tuning help!!!!

Allen T

[kdh77]

Does anybody know where I can get a manual for a mbx? I recently got one in a trade and it didn't come with one. I'd like to have one for the parts lists etc....

[Dnmeistr]

Here a pic of my buggy with 2.2 Masher tires.

[Crashbot2001]

DNmeister, that looks pretty wicked

ADA Just a note: do not use thread lock on the screws that hold the two braces to the steering posts. I did. Some leaked in between the post and the brass sleeve and the brass sleeve no longer was moving freely on the post. Was having a wicked time figuring out why my steering was binding.

[-=ADA$=-]

thanks very much i was just lock tighting everything, and when took a break and read your post, i was just going to do this, what else should i locktight?? cause i have put it on screws that hold radio tray, only this, i dont know where else to put it, i know all metal to metal conectoins, but i can find more of them,

[coyote660]

hey kdh77...ofna's web site,,,search "ofna racing" and go to "need a manual?"

[kdh77]

the site always says "under construction"
under the manuals section

[coyote660]

just go to "contact" and send em an e-mail,,,

[Crashbot2001]

ADA, all the shock mount screws need them on the towers. That's about it.
The only other place I know of is INSIDE the shock, there's supposedly a nut that could use it but I didn;t feel like tearing my shocks apart so I didn;t do it. No problems yet. Springs are too soft though

I already lost my front brake disc somehow. I think it musta blown apart becasue it was just gone when I finished running.. lol.. Also lost two of the engine mount screws. No idea how I managed that! Also lost one of the grub screws that holds the collar on the rear sway bar, so I pulled all of them and got 4 3mm by 5mm phillips screws and used them instead with a dab of threadlock.. No further problems in that area.

www.ace-hobbies.com now has parts listed for the MBX R2, so I'm gonna order a set of carbon fiber discs.

[-=ADA$=-]

thanks man ill thread lock the screws tommorow when ill get back from school, yea springs are too soft i had to add the two biggest preloads to keep the shocks un-squeezed, and what brakes was there like unknown fiber, probably i have same, so ill get them ASAP, thanks for help and input, im trying to get my parents to give me credit for and engine :) man i want to go and see how it fly's.

[prevelige]

OK guys,

I'm new to nitro, and something broke in my front diff of my ultra lx gt. How much difference would a torsen diff make? What is the difference? I guess I'd have to replace 2 or all 3 at once? Any other suggestions on upgrades/changes?

Thanks.

[-=ADA$=-]

the difference is the torsen will give most power to wheel with the most traction, but both wheels got to have traction, just any, if there will be no traction on one wheel, the diff will unload like normal, and its adviced to switch to torsen in center and front, but not rear, but probably you could fit torsen into rear

[Crashbot2001]

What ada said is exactly right(from my limited knowledge).

Most do not run Torsen diffs in the rear. I think it causes handling problems in turns..

Just center and front. If you're upgrading one at a time, get the center first.

Good Luck..

By the way

www.ace-hobbies.com has em for 99 bucks

[coyote660]

hey prevelige...save yourself some bucks and just replace whatever broke with hardened steel and get back on the road.

[-=ADA$=-]

yea the diff is noticed only on loose surface ( i think)

[bally]

Hi guys, just thought I'd let you all know, the cheapest place Ive found for Ofna parts is Ebay.com. Sounds dumb but I just got the Hyper 21RTurbo for $100 + $9 delivery. The Hyper 7 was $285. Just type in Ofna and you'll get about 300 adds pop up. And to be honest most of it is brand new sealed in the box.
Happy racing

[-=ADA$=-]

as i know most of time it says its in the box which isnt always true, adn have you recieved the engine already??

[fenix]

i want to buy a ofna mbx with picco engine?
do you recommend?
thanks

[-=ADA$=-]

i dont have picco engine but im sure you wont be dissapointed with this buggy, i love it, though i dont have engine yet.

[oohnoo]

HiHo Everyone.
Glad to see a site for the MBX. I have actually 2 of them. One is the MBX and the other is a MBX R2 with the ball joint rear. The MBX is all stock with the execption of upgraded servo's and pipe. The R2 is still in the building stage but will have the new Hyper 21 8-Port motor. I am also converting the R2 to the Ofna GTP onroad car. Simple upgrade that Ofna sells. The kit consists of the GTP car of your choice, upgraded shock tower, front bumper and 2 sets of onraod wheels! This way I can run the car onroad and off in the way they were meant to run.
The only week area I see is in the steering. I have upgrade to the aluminum servo posts and must say this tightened up the front alot. Also it seems the front shock mount which holds the upper arm is a weak link, the pin is sloppy in this hole which causes play in the steering. I'm in the process of making my own out of aluminum to tighten up this area.

Does anyone have the manual for the MBX R2?? If possible to scan it and mail or email it to me.
Also looking for the manual for the GTP.
Any help would be appreciated. I will be willing to pay for the shipping if need be. Send me a private email
Thanks

[-=ADA$=-]

i have one, but dont have scaner, ill try to go to my friend, and do it, but i cant promise everything, also check cause i have two maunals, and my mbx is like two kits together, it has radio tray, and radio box from ultra gt, and rest from mbx r2, so ill try

[oohnoo]

HiHo
I appreciate it. It's setting up the suspension on the MBX R2 that I need help with, just eyeballing it for now. I have the manual for the MBX, but that doesn't show the pivotball rear suspension.
Thanks

[prevelige]

Try hongnor. They have most if not all the manuals on the website, and since they actually make the cars for Ofna...
www.hongnor.com (http://www.hongnor.com)

[oohnoo]

HiHo
Went to that site and I like that it shows all the options for these cars but it doesn't have any links of where to buy from. I has the manual for the MBX but not the MBX R2 or the GTP.

[-=ADA$=-]

sorry i talked to a friend and he said that hes scaner is out of order for about a month, but tell me what do you want to know and ill tell you from manual

[oohnoo]

HiHo
Just need info on setting up the rear ball suspension. Caster,camber, toe-in, what would be the intial setup.

Thanks

[-=ADA$=-]

dunno if this is what you want but ill type what last page says
camber should be 0 or -1 degree in rear, and there isnt anything said about front.
and toe-in and caster isnt given, so only camber is what they suggest

[Crashbot2001]

Hey guys. Do they make a clutch nut or clutch nut adapter that will allow me to mount the OFNA MBX R2 clutch on an engine with the loger smooth shaft and threads up by the engine case( I think this is called a Pilot Shaft, but I dunno).

I know I could cut the shaft, but would rather not if there is a reasonably priced nut or adapter. Thanks!

Mike

[oohnoo]

HiHo
What you need is a Clutch Nut for a SG pilot shaft Ofna part # OFN10098

[Crashbot2001]

oohnoo, thanks.

I saw that part on Ace's site and I thought that was what I would need but I wanted to be sure.

Thanks again

[-=ADA$=-]

so Crash hows the performace of MBX?? hows the speed, and acceleration?? are you pleased with this buggy, i cant tell yet cause i dont heve engine but im sure it will be blast

[Crashbot2001]

ADA, it's awesome.. I love it.. Springs are weak.. Need stronger ones.. Other than that.. Man it's fast, and much easier to drive than the XXXNT!

[MitchellXXX]

ok this looks like were i need to ask my questions i just got me a ofna 9.5 rtr and my carb screws are all out of turn all three the motor is the p4 force pullstart and if any one could give me ideas on how to adjust it to breakin and good tips on the ofna motors i would appreciate it.

[-=ADA$=-]

Crash thets cool, im still gathering money to get engine im thinking of hyper 8-port, just to have an engine and than ill get some job so maybe something better some RB or collari, and yeah springs are very weak, i read that kyosho springs work good
*edit: and mitchel the settings should be high speed- 1-1/2 to 2 turns from closed , low speed- flush with the carb and mid needle shoulnt be touched ( thats how written here) no info about that needle

[SkyLineGTR]

is the OFNA GT LX good????? and if not why??????????

[MitchellXXX]

thanks ada$ but i think all the screws have been turned diifrent ways

[MitchellXXX]

thanks ada$ but i think all the screws have been turned diifrent ways, but i'll try to set them like that thanks.

sorry for double posts

[littlej72]

I was wondering if anyone has any set up tips for my MBX R2 particularly suspension. I have the center diff with super heavy oil and the front with 7000 rear with 3000, an os RZ01 rb 063 one piece pipe, hi torque servo digi, and some trinity pin tires. It's starting to handle pretty good, but I have to use a bunch of spring spacers to keep from bottoming out. I have heard of using mugen piston but I dont know the part # of the ones that fit and also im trying to get some kyosho white springs. ANY TIPS!? thanks!

[Crashbot2001]

littleJ72, the stock silver springs that come with the kit are too soft. Get the OFna White Springs, or if the Kyoshos fit(I don't know if they do) you could use them.

This brings me to my question.

Does anyone know of any line of springs that fit's the MBX R2 shocks?

[Vmax911]

I use kyosho white (firm) springs on my MBX R2. They are a little longer than the ofna springs, but that just means you don't have to use as many preload spacers. They work great.

So the kyosho springs fit. Also, the regualr Mugen springs fit as well. I haven't tried anything else.

Thanks, I also found that the springs offered for the OFNA hyper 7 and 9.5 all fit the MBX as well. I sispected they did, but wasn't sure iof those buggies came with similar shocks. Appearantly they do.

[morfracerX]

wow Vmax you're still alive, lol. long time man.

[Vmax911]

Yeah, I'm still alive. I even try to run RC's every now and then when I'm not at school (which means practically never).

Morf, back from the old RCCB days... still got the Worlds 2?

[coyote660]

palm trees in Lancaster??...welcome back.

[morfracerX]

I wish i still had my W2, i sold it a few months back. i now have a monster pirate (my 4th one). i also moved from lancaster to westhill, there is alot more trees down here.

[LosiGuy62314]

hey everyone, im in the market for a new car and im considering the Ofna LX Pro RTR, im gonna swap out the radio gear for a JR XR2 system from my xxxnt and add a hitec digital steering servo and hitec bb servo for throttle. id like some opinions on the car and setup. any answers greatly appreciated.

thanx

[morfracerX]

well seeing that your going to spend the cash anyway and that you wont havce to build it, why not go with the mxb r2+. it's the worlds2 (from what a bird told me) with the mbx set up at all four. The GTLX has no front kick up at all and that can be a real downer when racer or bashing.


Just me 2cent
PS, you might also want to take a look on ebay, they often havce some great deals on buggys.

[LosiGuy62314]

the only reason i would get the gt lx rtr is because they don't offer it as an 80% kit. if they offered it in kit form, i would for sure get that because when you build it yourself, you know exactly what you did when u put it together and theres less of a chance of things goin wrong. and no, the MBX R2+ RTR is not the worlds 2 from what i can gather. the worlds 2 costs alot more.

[RJ88]

I just purchased an mbx rtr, where on the internet is the best place to get parts? I looked on Tower and they only had about 4 parts. Are parts from the other ofna buggies inerchangeable? I bought the buggy because of the price, is it a good purchase?

[Vmax911]

Unfortunately, PRICE shouldn't be the ONLY reason you purchase a buggy. Sometimes you have to look at parts availability, durability, and popularity. :rolleyes:

alot of OFNA parts are interchangeable.

[-=ADA$=-]

as i know some parts are interchangeble between ultra and worlds series

[morfracerX]

You're right ADA$, a bunch of OFNA parts can be tossed around from kit to kit. Ihave a box full of GTP parts (thanks LR) that will work on my monster pirate or if i still had it my worlds 2. One of the main reasons i love ofna, is the way their cars or set up. you can buy one car and if you get sick of it just buy $100 worth of parts and you have a new car.

[Vmax911]

Holy cow! Lost Racer, what ever happened to that guy?

[morfracerX]

He's still around (the old timer), he is the one that got me into this 1/8 mess as i remeber.

[95M3]

Hello guys I am new to this forum and to 1/8 offroad gas. I just ordered a Monster Pirate from Nitro house, kit and .21 motor for $269.00 to cheap to resist.
My intent is to have a car that I can race and bash around and it looks like the main chassis is very simular on all OFNA's cars. The Pirate looks a bit stronger than some so that is why I chose it.
My one question is will the Torsen Diff's fit in the Pirate as well ? They look like it but the Diff housings are slightly different anyone know for sure ?

[oohnoo]

HiHo
Ace-Hobbies (http://www.ace-hobbies.com/2.2/catalog/default.php) has them for $229.
I am debating getting one, very tempting for that price including the Hyper 21 motor. With no motor it's 189.99.
How is this Monster truck compaired to others?

[-=ADA$=-]

as i know its very tough and reliable truck and with that price you can sell engine on e bay, and put in something better, cause it puts the price of an engine down to $0 almost

[ROD B]

hey guys i recently got a lx pro w/ the .25.
i did not know what to expect not to many r/cers have down here .
but iwas empressed w/ the car from the start.
i had some tuning probs at first but a trip to lhs got me on the right track.
i read some of the threads you guys put up and i say i made a wise buy i got a chance to see the worlds buggy
and theres not much differance between them
it has front kick up from the factory threaded shocks
low pro engine screws. etc,etc
i figured i would do some test laps in the back yard for break in
and i found that the back yard is smaller than i thought
even at break in settings this thing is awesome.
if any one has advice on tuning it it would be greatly appreciated.

[-=ADA$=-]

high speed neelde first, and tune for performance not for temperature,

I got my LX PRO about a week ago and i'm on tank 8 and
still running way rich and the buggy is just awsome. The one
thing I did have to do is I got it muddy and I took the engine
and radio gear out to clean it all and at that time I went through
and aplied fresh blue locktite to all srew to metal part, the thing
just rattles the screws loose, don't have that problum with my

[ROD B]

thank you guys so your saying ADA never mind how hot it gets
because noticed it likes to run warm, warm enough to sizzle the spit in the bottom of the heat sink. and theres no lose screws yet
(except the ones in my head) i do mostly cruisings through the grass so it does not get too dirty.
thanks for the input.
ADA about how far is the hi spd needle out on your ofna motor?

[-=ADA$=-]

the funny thing is (well its not so funny for me) that i dont have the motor yet, i bought MBX R2, without engine, and now im gathering money for engine, and im tweaking the car, so itl be perfect for first fun, i cant wait no more,

[Yogi]

ADA$

? for ya, does your MBX R2 come with 8mm axles
or are they the 6mm axles? I ask because I did
about 6 cart wheels and drove away with a bent
front axle. I replaced the axle, but would like to upgrade
the axles and bearings to 8mm on the front end.
theres a complete front end for sale on ebay.

Thanks for any info,
Jeff:)

[ROD B]

hey ADA$ the hyper 8 port is under 200 $at nitro house
i was gonna get the mbx r2 but figured i'd save a few bucks after my research.
i saw the picco edition r2 its nice but i kinda laughed to my self because the picco motor has only 1.9 bhp and the .25 that came in the lx pro has 2.39 bhp
but the hyper 8 port has 2.5 so it would probably a great engine for the price. i cant wait til i can start leaning her out.
even now the car draws a crowd (wich kinda sucks, all the ?s)
i dont know if ill ever do 10th scale touring again

[-=ADA$=-]

i think i have 6mm axles, and i think that 8mm is great upgrade, whats the cost of them?? and about engine, yea i was looking at 8-port, and i saw it at ultimate hobbies for $120 or so, but they dont ship to europe, and dont answer to mails, so i have to get more, and probably get it from nitro house, thanks alot

[Yogi]

I found a upgrade for the M.P. that is $82 dollars,
I emailed OFNA to see if it will work for the LX PRO
and if yours are 6mm then it might work for you too.
I had to replace a axle allready, and that was $38 bucks,
but for the $82 you get front and rear with bearings and all.
The hyper 8 port will be my next engine too. My .25 is on tank
12 right now, but when it wears out,( it will be hyper time).



:D :D

[oohnoo]

HiHo Yogi
What upgrade for the Mp are you talkiong about for $82?? And where did you see this? Any links?

[Yogi]

The upgrade is at Tower hobbies

http://www2.towerhobbies.com/cgi-bin/wti0001p.pgm?Q=1&I=LXCBB1&P=7

I hope OFNA e-mails me if the kit will fit the LX PRO

Later,
Yogi

[ROD B]

hey yogi i got the same rig but im only on tank 6
how does that thing run all leaned out
and does it get hot

[Yogi]

It runs great, I do tune for performance now and when I check
the temp. after a hard lap or two it's right around 300 degs.
If I let it ldle for a few second the temp starts to drop and will
level out around 275 degs. I do use a heat gun to warm the
engine, way easy to start then. Had to clean and reglue the
tires once allready. Thing is just insane compared to my MAXX.
Did take the rear sway bar off for the rough track by my house.



:D :D

[Vmax911]

Hey guys,

The MBX R2 does come with 8mm drive axles. In fact they are CVA's. If you are interested, I have a front end setup off of an MBX R2. E-mail or PM me for more info.

[mercenario27]

I met the guy from http://www.geocities.com/ssrcparts he said he can make me new shock towers for my MBX R2, is there anything I should have him change about the shock towers. They will be CNC 7075-T6. He was considering making aluminum arms for the GTLX since it was so popular and people only bash them not race them. Is there anything else I should ask him to make??

[-=ADA$=-]

and what would be price of these towers?? maybe diff housings, or bulkheads

[p.n.e]

hey guys, i've been running electric for awhile and i think i might get a nitro. right now im stuck between a tmaxx 2.5 and a ofna buggy. what are the advantages of a buggy? and which one should i look at? i'm looking for something easy to tune, really durable, and ok speed. my only concern is that i might bust the buggy going over ramps and in deep snow, etc.

[PCC]

I have an OFNA Ultra GT (now upgraded to almost Ultra Worlds 2) and I will tell you that the buggy is a lot tougher than my T-Maxx. I haven't seen the new 2.5 run, yet, but my buggy will easily outrun my T. About the only thing the T-Maxx will do better is climbing/crawling and taking jumps from ramps that are inclined more than 40 degrees (read: more air than distance). Buggies are speed demons on dirt and are tough because they have to be. The T-Maxx is more of an entry-level type of RC and can take some abuse out of the box but you will soon find that the mosly plastic construction will mean that you will be replacing parts on it on a regular basis.

Don't get me wrong, though. Both are fun RCs. The Buggy is more for speed and is tougher while the T-Maxx is great for impressing the neighborhood kids, popping wheelies, going over things, and doing insane jumps.

[p.n.e]

alrite now its down to either a ultra lx pro, or a 2.5 tmaxx. is the lx pro a good beginner nitro? what top speeds? how many speeds does it have? is it 2wd or 4wd? tower has it for 300 and this sounds like an awesome deal.

[DeadCow]

What glow plugs are you guys using on the new .25 engine??

[anothermbdusted]

Im using the Mccoy MC-9,8 plug and have found that in my ofna 9.5 that the .25 force engine runs about 270-285 for good performance.I will say to all here that after running it more often you will notice your temps going down abit though.I got a buddy that has 1.5 gallons through it already and he said that his temps have dropped almost 15 degrees from when he first got the motor in his kit.(I take it that its caused by less friction in the motor?) I have run about 15 tanks through it so far and it takes a while to warm up (1 or 2 laps)but once it does its a pretty good little engine. Its no picco or novarossi but hey its a good motor to begin with and has lots of torque to keep up on a tight track it just dont got legs to keep up with the big boys on the streight aways thats all.

[-=ADA$=-]

its 4wd, 1 speed (with center diff),

[p.n.e]

thanks! i've made up my mind, buggy it is! :D some guy on ebay is selling his mbx he turned into a monster truck by mounting pirate tires on to it. is this possible? with the right gearing?

[Vmax911]

Yes, you can put monster pirate tires on a buggy. In fact, I did it with my Ofna buggy. I had to trim the inside of the back of the rims to get the suspension to clear properly.

If you are interested, I have put these tires on E-bay Item number: 1787076044.

PS-my buggy with OS RG is soon to follow....

[p.n.e]

very nice, got any pics of them on your buggy? what kinda clearance do u get with them?

[DeadCow]

You should be able to use the MT3 wheels (Dominator wheels) on the OFNA buggys, whit them you can use any tire made to fit the T/E-MAXX

[-=ADA$=-]

to be true, MP tires are much, much better than Maxx tires are IMO

[Vmax911]

You know, I really should have taken more pics with the MP tires.... Here's a pic of the Ofna with the MP tires next to my Mugen XR which is next to my HPI MT Racer. :)

The box on the MBX R2 will not fit the sid by side

in the box on my LX PRO buggy, and thats the same box
on the MBX R2.

Money is not a problem I just wanted a good buggy to pretty much bash around with cause they don't have .21 classes at the track near my home...

I was looking at the GS Storm and the Ofna Ultra LX Pro .25

What do you guys think about the .25? I know that some of the other motors that Ofna makes has alot more HP and is alot better.

Just wondering which of the 2 would be best and is very durable...

[Skribble]

Hyper .21 8 Port is good .. $130. You can get a RB Concepts S7 Europa for $220, but you need a starter box. .21 in a NMT? You're going to be breaking parts like mad.

[dannyboy75555]

breakin parts is my excuse for upgrading lol to alum alloy and titanium

[PCC]

Unfortunately, the parts you will be breaking no one makes in Titanium or aluminum alloy. My bro ran a 21RG (1.9HP) in a NMT and he was constantly breaking things on his truck until he gave up and swapped the 21 for a 12CV-X.

The HPI guys on the US and European forums pretty strongly recommend not going with anything stronger than an Ofny Hyper .21 engine in a converted NMT. Those are pretty cheap, but then you have to pay for the conversion kit as well. Personally, I'd go with an O.S. CV-RX 15 or wait for an Orion Wasp 15. More money than the Ofna Hyper, but you don't have to get the conversion kit, and those engines have lots o' power.

[doesgo]

I've got a line on a good deal for an Ofna GT LX buggy that's brand-new and is RTR. It's got the Airtronics Blazer radio and Force P4 engine.

What do I need to do to it before running it for the first time? I mean stuff they don't mention in the manual. I assume they don't Loctite the metal-to-metal screws at the factory, do they? What other tips can you offer for this first-time 1/8-scale buggy guy?

Also, what are the typical early replacement parts and upgrades for this buggy? I know it's the bottom-feeder in Ofna's line, but the price is right and I'm just a basher, not a racer. I'm looking for reasonable durability and performance, a 90% vehicle. I don't care so much about tweaking that last 5% of ultimate goodness out of it with specialized tuning or changing the shock oil to suit conditions and stuff. Just looking for the basic stuff.

Thanks!

[doesgo]

Wait, I'm looking for a 90% vehicle, I don't care about the last 5%.... What happened to that second-to-last 5%? :D Sheesh.

[NitroRookie]

Would It be a better buggy than the Duratrax Axis RTR Buggy ?

your buddy will need to find a worlds II chassis, or possibly one for am MBX R2 Plus (a limited edition car). Last I checked Ace (http://www.ace-hobbies.com) had the W2 chassis.

Ofna's website is rather incomplete, so I'll ask you guys. What's the difference between the Ultra GT LX RTR and the Ultra LX Pro RTR besides the engine? Is the Pro vastly better? Say, $50 better?

HEY DOESGO I JUST BOUGHT A LX PRO A FEW WEEKS AGO AND IT IS THE $&*T THE DIFFERENCES THAT I NOTICED IS THREADED SHOCKS FROM THE 9.5 A FRONT KICK UP CHASSIS WICH REALLY IMPORTANT TO ALOT OF FORUM BASHERS THE OBVIOUSLY LRGR MOTOR AND WILL READY FIT ALL THE HOP UPS POSTED @ THE OFNA WEB SITE UNDER LX PRO AND IT LOOKS TO BE ABLE TO FIT SOME 9.5 CHASSIS PARTS BRACES TOWERS ETC. IN MY OPINION

:D

[doesgo]

Thanks for the info, Rod.

[anothermbdusted]

hey has anyone ever put on monster trk rims and tires on to a ofna buggy befor?were thinking of starting a new class for monster trk racing like the dominator and the tmaxx and anyone that wants to convert their buggy to a truck but i have no idea what rims and tires will fit.I have a 9.5 can someone help with this?

[doesgo]

Look back 2-3 pages and you'll see that subject discussed. Someone is even selling Dominator (or was it Pirate?) wheels/tires that he took off his buggy. There's a picture there, too.

[Vmax911]

Yeah, I'm selling some Monster Pirate tires I had on my buggy :)

[PCC]

MP wheels and tires are too big to work on a buggy without changing the spur gear to a pizza-sized 66T MP deal (requires a conversion kit to fit). Recommended would be the wheels for the Pirate 10 which fit T-Maxx tires. The smaller (than MP tires) T-Maxx tires and a small clutchbell will give you what you are looking for. I forget if the Dominator uses the larger wheels/tires of the Monster Pirate or the smaller ones from the Pirate 10.

[-=ADA$=-]

if putting dominator, or maxx like wheels, its like putting normal buggy wheels on, its better to put on MP tires and wheels, andyou dont have to change the spur, it will have worst acceleration, but change in clutchbell would be enaugh i think,

[anothermbdusted]

I want to put something about the size of a Tmaxx's tire onto my 9.5 if is it possible?I saw that proline makes a 17mm to tmaxx style rims converter.my biggest question I guess should be will tmaxx sized rims fit onto a 9.5 with no clearence problems at all?and if not then what do you got to do to make them fit?and does anyone have pictures of a ofna with tmaxx sized tires on it?sorry for all the questions I just dont want to go buy the rims and tires then find out that they dont work or fit for that matter.

[Vmax911]

Actually the MP tires worked rather well, it wasn't as sluggish as I though it would be. I did gear down to a 12 tooth pinion though. They aren't much bigger in diameter than the Dominatior tires, but they are a lot wider.

[-=ADA$=-]

i think that it will be hard to put maxx rims on buggy, but u can use dominator MT3 splits on buggy, and put on them maxx tires

[LkHse]

I dunno if this was asked before, but how is the Ultra LX Pro in terms of durability , and being able to handle big jumps and flipping and things, i know it is plenty fast, any thing offroad that goes over 45 is fast. How is this buggy in terms of durabillity?

[anothermbdusted]

ADA$ so the tri spoke dominator wheels(81154) will fit no problems at all?i thought that it was proline that sells the adapter and it is ofna that sells the adapter to put T Maxx tires on to a vehicle with 17mm hubs.have you done this yourself befor so you know for sure or are you speculating that it will work?do you got pics?

Vmax911 thank you for your imput on this but i really want to try to stick to the size of rims,tires that a tmaxx has and no bigger.but i will keep it in mind though and thank you

[PCC]

My buddy is running the Dominator wheels on his Monster Pirate. The Pirate uses the same 17mm hex as our buggies do. I loaned him a set of well worn wheels/tires from my buggy to break in his engine on that MP and they bolted up, no problems.

OFNA makes adapters to fit buggy wheels on a T-Maxx, I don't know of anyone making an adapter to let you install T-Maxx wheels on a buggy.

[-=ADA$=-]

as i know dominator as well as MP is based on buggy so wheels should fit.

[LkHse]

Can anyone answer my question about the Ultra LX Pro(whatever the 300$ buggy is) ?

[p.n.e]

yea i was curious about that too. should i save for a hyper 7 instead? some people said all the ultra series had bad plastic and cheap metal, etc. but im just looking for a bashing buggy not a racer and wanna spend as little as possible. are the ultra series made by ho bao or hong nor?

rod b, hows the quality/craftsmanship like on the lx pro?

[-=ADA$=-]

i think ultras are made by hong nor, and its not cheap plastic and metal, its better quality than my kyosho truck ( i know its now best but MBX i have is better)

[doesgo]

You can get the Ultra GT LX RTR from Ultimate Hobbies for $260 right now.

[LkHse]

So its good quality, and worth spending the money on?

[Lost Racer1]

I've ran both Hong Nor's and Ho Baos buggies(Worlds 2 and Hyper 7 Pro)
I do have to say I wa simpressed with the toughness of my Worlds 2 buggy. It went through quite a bit of punishment. In my 2 years of owning it, I went through 3 arms and 2 shocktowers total. I bashed, raced and crashed it numerous times. If you're just looking to bash the Hong Nor series would work well for you.

If you're looking into racing I'd say go with the Ho Bao model. For me it was damn near indestructable!! Shock shafts were the ONLY things I ever broke on it. And I raced it every weeekend!!And ran it at least everyother day.

Bottom line: Both are great quality. If your main interest is bashing go with the LX. If you plan on racing go Hyper 7(Ho Bao) or 9.5(Hong Nor)

[bigedogg]

I have an LX PRO RTR and the axles bend and break even with the upgraded cva's (after only 2 tanks on the track!) but other than that it rulz with the .25. I wouldnt buy one until they put the 8mm shafts in there. Hopefully they will fix it because they really do suck. If n e one else has the same problems lmk on the board.:(

[ROD B]

HEY P.N.E. I HAVE HAD MY BUGGY FOR ALMOST A MONTH NOW
AND THE ONLY THING THAT WENT WRONG WAS A STRIPPED DIF BUT THAT WAS A FACTORY DEFECT AND THEY SENT ME THE PARTS FOR FREE THIS PAST WEEKEND ABUDDY AND I WENT TO A CONSTRUCTION SITE TO RUN THE BUGGY AND T MAXX
AND I DROVE IT LIKE STOLE IT ALL WEEKEND AND HELD UP GREAT
NO BROKEN PARTS I HIT A STICK IN THE DIRT @SPEED IT BENT THE CVD BUT BENT IT BACK NO HARM DONE
I WOULD SAY ITS TOUGHER THAN THE T MAXX AND CLIMBS BETTER
MY ONLY REGRET IS THAT I DID NOT BUY IT WHEN I 1ST GOT INTO NITRO R/C
THE GUY I WAS W/ HAS FRIEND W/A GS STORM AND MY FRIEND IS MORE IMPRESSED W/ THE OFNA LX PRO
DO TO OUT OF THE BOX PERFORMANCE DURABILITY AND PRICING
HOPE THAT HELPS DUDE

[OrcSlayer]

Ofna's selection of buggies is confusing. I want a RTR buggy. I read the last few pages and it seems the MBX buggies are better qualiy than the GT LX series. I was looking at the Ultra MBX Force at Tower and the GT LX Pro with the .25 engine. The MBX is 80 bucks more, but I don't mind if I will save that 80 bucks in parts I would have spent fixing my car later on. I need a car that has no real weak parts and will stand up to bashing. I will be keeping the engine and radio stock. The springs should be stiff enough to take 2-3 foot high jumps without bottoming out and the buggy tough enough to take them without breaking, though I couldn't see any car breaking from that. Both my friend's Nitro Demon and my other friend's TTR buggy (not the EB4, can't remember which model it is) have springs so soft if you compress the suspension, it doesnt rebound. I wouldn't want to jump a car sprung like that. Also, how would these buggies compare with the Axis and that new Hot Bodies buggy that's out now? Is the MBX worth the extra money over the LX Pro? Thanks.

[p.n.e]

you can always put in stiffer springs and heavier shock oil, maybe they set theirs up like that on purpose to absorb bumpy terrain. springs are cheap and so is shock oil. IMO nitro demon is the ugliest r/c ever made:p

[OrcSlayer]

Yeah, it is. But Tower had them for $250 RTR vs. $380 for an Axis. I would have gotten the Demon too. It seems to alway be broken though. The suspension arms flex so much that my friend had a dogbone pop out of place when he hit something. Other problems it has had is screw falling out which is his fault for not locktiting them. He also blew his clutch trying to climb a curb. That's what I think he did, but we haven't taken it apart to look.

[p.n.e]

i think duratrax has stopped producing them, it was off their web page a while ago. 250 rtr :eek:...well you get what ya pay for i guess. does the demon even fall into a catagory of r/c, its not quite a staduim truck and not a mt either..
as for jumping, even my evader will take 2-3 feet lol. buggies are built pretty darn tuff i hear.


one last question before i order, does the lx pro have cva's? or just univerals? if universals, are they steel? thx

[OrcSlayer]

Yeahit was on sale, then production stopped. I guess Tower was just trying to get rid of them. The Demon is an offshoot of the Axis/Nitro Quake chassis. Its an Axis with shorter suspension arms basically. I'm sure buggies can take 2-3 foot jumps. We've taken em with the Demon, but I don't want my car bottoming out on them. I could get springs and shock oil, but I bet the springs at least would be horribly overpriced like most r/c parts. :p

[bigedogg]

the lx pro has universals in the front and dogbones in the back and they are steel.They sent me the CVA's and they bent to so i dunno what is up with them but if u order one good luck.

[p.n.e]

what exactly do you mean by dogbones in the back and universals in the front? isnt the dogbone the part that connects to the diff out drives and the universal connects to the axel?

[Lost Racer1]

A dogbone connects to nothing. Its just a loose axle thats able to pop out and bend at will:rolleyes:

CVD or CVA or Universal..All pretty much the same thing initially.

CVD=Constant Velocity (Drive) This is your center drive shafts

CVA=Constant Velocity Axle<--This is what drives the wheels

Someone please correct me if I'm flawed :D

[doesgo]

I think you're right for the most part, but what about CVDs in stadium trucks, for instance? Are they technically CVAs? Is CVD a trade name owned by MIP?

Universals are slightly different from CVAs/CVDs. Functionally they're about the same, but universals are like a 1:1 RWD car's driveshaft and universal joints. CVAs/CVDs are more of a ball-and-socket design with a small pin to hold them together.

[OrcSlayer]

Sooo.... can someone please help me decide between the LX Pro and the MBX RTR? Thanks. :)

[mimlitkm]

Hello all. I'm new to this forum, I have the same question OrcSlayer has. I have only worked with electric on-road cars and looking to move to off-road buggy. A friend told me to go with an OFNA buggy, but I'm unsure of which one I should go with. Any info would help alot.

Thanks,
Ken:confused:

[Crashbot2001]

Lost racer.. Lol on the dogbones...

OrcSlayer, if it was betweent hose two, I would get the LX.

What do you want to do with it? If you wanna race, get a hyper 7 Pro. I had an MBX R2.. No more.. here's My baby now:


http://www.imagestation.com/picture/sraid39/pe3f2cf12172e7589bb544802087a863b/fd05d0be.jpg

I put an RB C5 in it with Ofna's new One piece(though it's really two!) pipe... Holy Shingles....

[Lost Racer1]

Thanks doesgo. I wasn't sure on how to exactly word it. :)
But I think essentially CVAs\CVDs are the same from what you pointed out.
this is a universal http://www.ofna.com/images/ultLXpro-axle-BIG.jpg
This page has a pick of cva's\cvds http://www.ofna.com/images/opt-30071.jpg



mimlitkm and OrcSlayer: Have you dirven an 1/8 scale buggy before?
If so which ones? Kyosho? Mugen? I ask this because of the front suspension set up.

The GT LX Pro has a Kysosho type front suspension.

The MBX has the Pivot ball in front and rear.

Quality of make should be about the same being both made by Hong Nor.

I agree with Crashbot on the racing aspect. HOWEVER, if you are an adequate driver you can race just about anything with little problems.:D I sucked at racing so I sold My Worlds 2 and picked up a H7 Pro. FYI:Ultra Worlds 2=MBX R2 plus.

I noticed a difference in running the Hyper over the Ultra Series..

[OrcSlayer]

Thanks for the replies. :) I have driven my friend's Nitro Demon which is a quasi 1/8 buggy. If you see my post further up the page, you'll see I want to use it to bash with. Mainly, I want something durable. I can handle my admittedly poor handling and therefore hard to drive Nitro RS4 ok. I found the Demon to be a piece of cake to drive compared to it. Also, I want something fun to drive. If it's too overpowered, I'll be worried about crashing and breaking my expensive new toy the whole time I'm driving it and won't have fun. I'd love to get a Hyper 7/9.5/EB4/MP7.5/whatever Mugen makes these days but they are way too expensive and overkill for me.

[Crashbot2001]

If you're just gonna bash, get the LX.. Much cheaper and pretty tough..

I think 1/8s are much easier to drive than 2wd 1/10 scale trucks too!

[Archerboi]

I was thinking of getting the new Ultra GT LX pro RTR. Does anyone have it? And how is it out of the box and the quality?, how is that? And how does it run. Thanks in advance. :D

[doesgo]

I've heard the Force 25 in the LX Pro RTR is torquey enough to break the stock CVAs, but I'm not sure if that's just a rumor. I'd be willing to risk it! :D

i have heard this term used a lot, pivot ball suspension. could someone explain how it works? it just looks like it gives a bit of play to the wheels.. does the MBX have kick up in the chassis?

btw check out ofna's site, 9.5 mbx has been released

http://www.ofna.com/images/95mbx-axle-BIG.jpg
http://www.ofna.com/images/95mbx-deadon-BIG.jpg http://www.ofna.com/images/95mbx-head.jpg

[Lost Racer1]

In a pivot ball there are 2 points for adjusting your camber, One on top and one on bottom. Its suppose to help you be more precise in your adjustments.

The GTLX, and MBX series(except the R2 PLUS and PRO) do not have kickup.

[LkHse]

What does kickup on the chassis do?

[mimlitkm]

Thank you for the many replies. I have never driven a buggy, I've been into on-road cars, but racing is limited here. So myself and a couple of friends are looking into off-road stuff. I suck at racing so I need a car that handles well. I saw a GT LX Pro for $280, is this about what they run for? is this a good car? what kind of upgrades are needed out of the box?

Again thanks for the help,
Ken

[doesgo]

$280? Jeez, that's a great price! I got my GT LX for $260 off Ultimate Hobbies but the LX Pro is better, and for $280? Amazing. I wish I could return mine!

I really prefer 4WD for off-roading and bashing. I've got a couple stadium trucks that are fun, but not as fun as my HPI Nitro MT and I hope my new buggy will be just as fun as the HPI. I see no reason why it wouldn't be!

I like off-road because it can go anywhere, on-road or off. On-road is pretty much limited to smooth pavement.

[Lost Racer1]

Kickup gives your buggy the ablilty to pass over rough terrain without gouging your nose into every dip and hole in the track.
As well as allowing you to land jumps a bit more sloppilly;)

mimlitkm The LX Pro is a better car than the LX model was. And comes with kickup on the chassis. For bashing that would be a good choice for you IMO.

[OrcSlayer]

Thanks. People said to get the LX in the MBX forum too. I have a few questions though. I know it's RTR, but does it come with at least an exploded view to help with taking it apart for maint. and repairs? Yes, The LX Pro is surpirsingly affordable. Tower has them for $300, while the GT LX was $350. mimlitkm, where did you see it for $280?

[doesgo]

My GT LX came with an exploded view, so I'd guess the LX Pro would as well. Their instructions and views aren't NEARLY as good as HPI's, but I digress...

[Lost Racer1]

Orcslayer- Make sure you order the LX PRO and not the plain LX. there is a difference;)

[OrcSlayer]

Yeah, I just thought it was interesting Tower is selling the Pro for 50 bucks less. I'm gonna check my LHS to see if they have any. Asides from the chassis kick up, what other improvements did they make?

[morfracerX]

threaded shock bodies
a ofna .25
Steel Main Spur Gear
Sturdy Kickup Chassis
a better batt/radio box
a much better pipe(looks like the old worlds 2 pipe)

I never liked the rear "brace", all of the mbx/gtx buggies have them. i am a worlds 2 sucker, there is one on ebay right now with a ws7 for $300 (i would run with that)

LR is that you?

[morfracerX]

The LX pro off OFNA's site

http://www.ofna.com/ultLXpro.html

One other thing is the bodies that come with the pro are the lick.

[mimlitkm]

Thanks again for the help.
I found this one on ebay it was a display model that sat in a glass case. I was the high bidder, but reserve was not met. I asked him if he wanted to sell for that price. If not I did see it on Tower for $299, I'm going to check out the LHS tomorrow.

[crank throw wei]

I don't know if this has been asked and answered here yet(62 pages!),But has anyone else been having trouble with ring gears? I have put at least 6 in my MBX R2 since last X-mas! I've tryed shimming the ring so tight it feels a little notchy,replacing pinion bearing,and lock-titing the case screws in.No luck,they still have a short life.I have also used a high speed grease meant for power tool gears,and auto grease for cv joints(high lead content to stick better).The only thing I can think of is the housing is flexing to a point it lets the gears disengage enough to allow them to slip.I know their's an aluminum case available,but lots of $$ .ANY ideas?

Thanks,Duane

i have never had to shim a gear although i did blow two of my MP front diffs. Anyway give ofna a "CALL' they are very helpful when you call them.

[Lost Racer1]

Yeah its me Morf. when they moved the boards over I lost my original "Lost Racer" name. But was able to re-register with the 1 on the end :)

The R2 ring gear problem was well known..call Ofna. They were replacing them wih a hardened set.

[LkHse]

Dont put the # sign on and it come sup as a Hyper 7 for 259.00 $ buy it now. Its used

[crank throw wei]

Lost racer 1:Thanks for replying.I called ofna last January,and they did offer to replace the gear(the hobby shop also told me of soft gear problems).I didn't want to have the car out of service the time it would take to have one mailed.So I asked if the ones on the shelf also had this problem,and was assured that they didn't,it was a production problem.So I have bought now 7 gears to date,with the same problem each time! The gears almost seem TOO hard,as the teeth chip off,not bend as a soft metal would do.
I work with real cars for a living,so I know how to set one up properly,but I'm at my wits end!!! Any other ideas? It's almost always the rear,but it has happened to the front too.

[Lost Racer1]

crank throw wei -You are running diff oil right? Not grease.

[crank throw wei]

yes,7000 center,5000 front and rear.But what does that have to do with the ring gear? Those get greased,as I stated above.

[crank throw wei]

I don't know if you can see much detail from this pic,but this is what's happening.

[Lost Racer1]

Sorry..I've been steam cleaning carpets all day..My mind is in a buzz.

looks like the mesh is too tight..Let me see if I can find the posts on the shimming..I think someone was using a Kyosho shim set that worked out.

Edit: Found this on page 30.
"Big Wig....I used Kyosho BS-53 shims for the diff. It will probably take two packs.I think Ofna also has a diff shim set, but I have not used it, and can't find the part number now.

Rotor"

I'm still looking for more info..I don't know if that will fir the pinion though..I'll update when I find out.

[gkcontra]

Check your bearings as well, if they are dteriorated at all, the pinion will wiggle and cause the Chunking of teeth you see there. Also, it looks like your mesh may be too loose, you can tell because it doesn't look like the pinion ever touches the inside of the ring, if you shim it a bit, it will move the pinion in equal with the ring.
