Matt Francis XXX-T edition Forum

[losi]

I am selling my NXt racers kit and i am goin to get a Matt Francis XXX-T edition truck. Wut do u guys thing of the truck is it any good. Wuts the fastest motor i can put into it with upgrading any gears. Is it good at jumpin. If u own one is it any good let me know. I was thinking of puttin the Reedy sonic 2 modified in it wut do u guys think. Thanx. Post set up tips too. Thanx:D :D

[CharlesWA]

I picked one up last weekend. I've been running touring cars for quite a while. This will be my first attempt at off-road racing (I'm living about 2 minutes from an indoor off-road track now). I still need to glue up the tires and install electronics. I'm going to be running the truck in the local track's "Novice" (trucks and buggies w/ 24* stock motors) class. We'll see how this goes.

After building countless "normal" touring car shocks I can say that the Losi style shocks are a big pain. The cartridge is nice, but I can't seem to get them built without some air in them. :(

The only real tips I've got at this point are to be sure to trim stuff. Most of the molded graphite parts are a little rough where they came off of their parts trees. Take the time to smooth that out with a hobby knife or file. Also, be sure to trim any "flashing" off of the tires where they seat to the rims. Mine all had a fair amount on them. :( Curved lexan body scissors worked great for this. :)

Hopefully I'll have more to report on the truck in a couple of weeks after I've had it out on the track. :cool:

[losi]

I would really appreciate it if u told me how the truck handles and runs. Thanx. Also were did u get your truck and how much. Also how long did it take to build

[CharlesWA]

I bought my truck from my local track, Tacoma RC Raceway. I paid $249+tax. I'm sure you can find them online at all the usual big RC retailers (though not Tower Hobbies, though) for about that or a little less. Horizon Hobby has them for $249.99 here (http://www.horizonhobby.com/products/description.asp?prod=LOSA0075).

I picked up one MIP allen driver when I bought the kit (the small size that you use for a lot of the countersunk screws). I can't imagine assembling the kit without it. I want to get one or two other ones soon. Unfortunately most of the stuff I've got from running TCs is all metric.

I'm not sure exactly how long it took me to assemble. I've been working on it an hour or two each night after work this week. As for how it handles, that'll have to wait until after I get it on the track. :D

[losi]

Yea see i had the Team Losi NXT which i am tring to sell to buy the matt francis which also has all those little allen screws so i already have the allen keys which i guess is good cause of wut u said. also wut esc are u puttin in it. thanx and also wut motor

[CharlesWA]

That's true. You should be set for tools since you've already got another Losi truck.

I think I'll either use a Novak Dually or Cyclone. If the Dually fits I'll use it, but it might be a little too big to fit in the chassis. I'll probaby also use a Novak XXL receiver and some sort of ball bearing equipped Hitec servo. Just depends on what I want to rob out of some of the other cars. :D

As far as motors go... I've got a few Paradox (pre-P2K) stock motors that I haven't run in a while. I'll probably cut the comm on a couple of them, add fresh brushes, and see how they do on the dyno (old Tekin dyno). I think they have a little more torque than the more modern stock motors. And that's good for Off-Road (isn't it?).

[SirSpeedy]

There is already a Triple X-T Forum on this Board. Tons of information there.

Thanks.

[losi]

Yea but this one is only fore the Matt Francis edition not the stock one. :D

[SirSpeedy]

Same truck.

Goodbye thread.

[losi]

YEA SHUT UP:mad: :mad: :D

[chizzler]

no, it is different, its red, no no it cant go they are different...........

[RC-Nitroguy]

I am going to get one in a few weeks here. Its a worthy kit comes with threaded shock bodies and titanium turnbuckles never seen that in a truck kit before. someone is listening about what we want in a kit...

[losi]

Yea i am goin to be getting mine in november cause thats when my birthday i. I cant wait. If i sell my NXT earlier then i will get it the same day i get the money from it but until then i have to wait till november. :D

[losi]

Does a stock motor come with the kit. Is it any good the motor:confused:

[CharlesWA]

The XXT MF does not include a motor, nor does it include a pinion gear. It also requires a servo, receiver, and speed controller to complete. Additionally you need the usual stuff... Tools, glue (for the tires) and paint for the body.

It sounds like the truck should be setup pretty good out of the box for clay type tracks. That's the type of track that Team Losi does R&D on and consequently that's what the trucks and buggies are setup for out of the box. At least that's what the guys that work at the track tell me, one of which is a Losi driver. :D

[RC-Nitroguy]

Dude I am getting a MF XXXT friday from socal, anyways its my birthday and I am going to run my pieced together xxt. They cost 219 advertised on the web alot cheaper than my LHS. I still support my LHS but I also like getting a good deal.

[losi]

Anyone get there truck goin tell me how it handled and wut motor and ESC u have and also any tips on building it. Cant wait till i get mine:D

[RC-Nitroguy]

I got it on my Bday, and of course went together like a lego set. Its a really great valued kit and runs and handles Better than my XXTCR out of box, no comparision to a RC10T3 Factory team which I was thinking of getting earlier this year My XXTCR blows them away on any race day with a bad cold. But when I heard the losi team was coming up with a team kit I held out and boy was it worth it. Redeemed myself from all those crappy HPI kits I bought in the past. Since I am here rambling I wish my driving was as good as my building. I am nervous putting it out on the track so soon so I am still feeling it out. I just have to remember that its graphite.

[RC10T3]

losi, you can look for any xxx-t thread, the matt francis truck is no different from the others except its red. Its a marketing thing that Losi and Trinity are doing to sell more XXXt's. Anyways, since you seem to want to have a comment on ONLY the XXXT-MF, it handles great. It seems to have a little more punchy feel than the xxx-t becuase its a TINY bit lighter, but the T3 will stomp it in the acceleration department. Its only becuase of the tranny ratios. If your gonna get this expensive of a truck, dont put crappy electronics in it. A Novak Dually is dang good if you can find one, or get a used cyclone off ebay. Get a good motor, a Reedy MVP or Fantom P2k are good, and if your gonna run mod, only get a Fantom Ti or Trinity D4. For batteries, get RC-2400 or RC-2000 for stock classes, and Stock metal hydrides RC-3000s for Mod. The best batteries out there are B&T Blister packs, and SMC/Promatch. For radio, a futaba magnum JR will get you by fine. I have been running one for 4 years in my T3 and I have had about 10 glitches. If you plan on running indoor, stay away from the 75 mhz band, epecially the 60-70 channel, or you will glitch from the flourescent lights. Thats about it. The xxx-t is the best stadium truck out there, as much as it hurts to say it, its true. Associated hasnt released a stadium truck in about 4 years, so losi has a huge advantage right now. Go with it, you will find it that you wont push it to its limits on handling until you get into low turn mods.

[losifreak2004]

A T3 will not "stomp" the XXXT of the line, MF or not. The Losi tranny ratio is 2.45:1, the AE tranny is 2.41:1. How the driver gears the motor and what motor you use will decide who wins the drag race. If every variable possible was exactly the same, they would be darn near dead even.

The truck is not a "marketing ploy". The companies made much more on a stock kit then they do everytime they sell a MF or BK edition car. They did this to pay tribute to the drivers and say thanks to all of Losi's customers over the years.

Also, the biggest difference the graphite parts make is the stiffness of the truck. You will notice more handling difference than acceleration difference. The weight loss of all the graphite parts is nearly insignifcant.

That said, I've never heard a XXXT owner say they were disappointed by the kit. If that's not testimony to its quality and performance.

Note: 75 mhz radios in the 60-70 band range will not glitch anymore than anything else. If you are worried about, get an FM radio, anything from a JR XR3 to the Airtronics M8 or JR R-1. I have never heard or had this problem, and my local indoor track uses flourescent lights.

[RC10T3]

..

[losifreak2004]

Feel and actual performance are completely different. Are you trying to say carpet is more hooked up then clay tracks and slicks? There is no acceleration difference.

I'm not complaining, I'm just saying the truth.

[RC10T3]

woops

[SirSpeedy]

Aaron don't waste your time man.

There is a ton of very helpful info on the other thread. This is really stupid to start another, and lose all that great information.

I am really suprised that one of the guys has not closed this yet.....I actually thought it was already gone.

[Usagi]

I am sorry if I posted once before some where, but where can I get one of these for a cheap price? can you give me a link?!

[RC-Nitroguy]

I can get you a kit see your PM

[Kenro]

Hello all,
I just finished building my Matt Francis XXXT and I think it's pretty sweet so far. I just have one problem and it seems to be a big one. The front tires bounce like crazy, even when I hold the truck in one hand and spin the front tires they wobble a lot, like being off balanced. Do you balance off road tires? They are the stock tires, foam and rims that come with the kit, are they low quality? I thought the MF edition was a full race kit. The foam is in straight and not bunched up, I've already glued the tires to the rims. Any suggestions? I really dont wont to buy more tires and rims right now as the truck wasnt cheap, although it was $204.00 from my LHS.
Thanks in advance.
Kenro

[losifreak2004]

It could be that the foam bunched up after you glued them, or the glue puddled up on one side. Try reshaping them with your hands, and make sure the bearings are in straight. Tighten them done until the wheels spin freely, but don't slide on the axle.

If this doesn't fix it, send me a PM.

[Kenro]

I'm sorry, what is a PM?

[Kenro]

Oh, duh, personal message...LoL:rolleyes:

[losifreak2004]

LOL...kids :p

[Kenro]

Hey guys,
I recently finished my XXXTMF and wanted to know what you guys think of my paint job, I'm a novice but I used to build static models. Here's a pic.
kenro

[losifreak2004]

That is sweet! You sure it is sitting low enough though? Rear looks kinda high....

[makaluch]

I'm a nitro guy but I am also from Washington State and the weather does not allow me to drive the track for a few months out of the year...so I'm getting a MF XXXT ! Ya know,...just to keep my chops up.

I'm interested in racing one of the stock classes at Tacoma once I drive it for a while. So I'm wondering if there's any input on what pinion/motor combo works well for racing stock ? I've made up my mind to get top shelf electronics...Cyclone,XXL and eventually a Millennium Pro . Is the Pit Wizard necessary for stock ? Also what are the max Mah's for a stock class battery ? Can they(or is it necessary that they) be matched ? If that class doesn't allow matched cells then is it ok just to get a linear pulse charger ?(like one of the duratrax intellipeaks or the rhino)

Sorry for the drill, but I'm in sponge-mode now that my mind's made up...LOL:D Thanks guys ! >>>Mark

By the way...VERY NICE PAINT JOB !!! What masks did you use ?

[losifreak2004]

The Millenium Pro has a built in Pit Wizard. I am convinced that 2400's are the way to go for Stock racing, you can pick up good matched packs from Trinity for around $85 at good LHS's. I can't think of a class that wouldn't allow matched cells because there really is no way to check it without a matching machine, and that would take a while. For play around packs, however, a budget charger would be JUST fine. :D

The Losi manual has a recommended gearing chart on the inside of the second page. 20/88, 19/86 or 21/90 are good starting points.

[Kenro]

LosiFreak2004,
You think its too high? A guy a the track help me set it up, It does sit a little lower with the battery in it, plus there are two huge jumps at Showtime Speedway.

...I used XXX Main brand masks for the paint job, I had to cut them down as they were too large for the narrow MF body.

[losifreak2004]

Are your dogbones level? A little above it might actually help, it does on a gas truck. As with anything, try different settings and see what you like. If jumping is a problem, take a practice day to learn the timing of the jumps so you can land on the downside. The stock setup might be a little too soft for Bakersfield also......

That said, my truck sits a little lower than dogbones level.

[Mr.man]

hey losifreak2004 are you talking about Bakersfield California, if you are thats were I live.:)

[losifreak2004]

Yup, Bakersfield CA. Showtime RC Speedway....too bad it's so far from San Diego LOL.

[Kenro]

yep, Bakersfield, CA, that is where I live also, you run at Showtime RC Speedway?

[losifreak2004]

LOL no, I live in San Diego. I have only heard about Showtime, and good things of it.

[Kenro]

Sorry, I meant Mr.man

[Mr.man]

hey Kenro where is the Showtime RC Speedway at? I dont race yet but I've been to races only at the track at racers haven. I think I might of been to Showtime RC Speedway if it is on Chester ave. or somewhere else?

[Kenro]

Mr.man its at 3805 Chester Ave, at the museum, check out their website, http://www.showtimespeedway.com

[Mr.man]

yep I've been there :D its close to some batting cages too and there is a bike race track behind the rc track. do you race ther alot?

[Kenro]

-Mr.man- I've only practiced there, actually havent started racing yet, I'm new to the off-road scene, only raced dirt oval and thats been a long time ago. I just picked up some sanyo matched 2000's today so I will probably start racing the Sunday after next.

[Mr.man]

do you have to pay to practice there? if you do how much is it? sorry about the stupid questions but I might start racing off-road.:)

[Kenro]

no prob, no stupid questions. its $2.00 to practice, cant be that huh?

[Mr.man]

that is preaty cheap! :) how long do you get to practice?:confused:

[Mr.man]

when are the races held, sunday? just one more question: ho w much does it cost to race?

[Skribble]

$2.00? They charge? :confused: Racer's Haven has practices for free every Wednesday when the race season gets going. Man, I gotta see Showtime's new track. :( Need to sell my truck too to get a KE XXX. :)

[losifreak2004]

Yay! Racing buddies found on the internet LOL

[Mr.man]

hey Skribble, when does the race season start at racers haven? I think I am going to start racing and I might see you there, That is if you race. Is it true that stockdale high school has a ATM? Just curious!!:)

[Kenro]

season starts jan 11th at racers haven

[Mr.man]

Kenro, how much does it cost to race at racers haven?

[Mr.man]

:confused:

[Skribble]

[Skribble]

On Saturday, me and a couple friends with Mike and Joel practiced on the track. I broke a front a-arm and lost a hinge pin. :mad: Than my electronics kept coming off because the sticky-tape wasn't holding on for some reason.

Mike cleared the triple with his buggy and a Birdman motor. :)

[Exterminator]

I have not heard of a class of racing out side of SPEC racing that controls the type of batteries (matched/unmached) a person can run. I have been using the SMH3000 with great success. I have not tried the UMH yet but I have some experience with the Sanyo 3000 HV and they are great for stock also. Most new motors are great. I would suggest a P2k2 or a Core/Hellfire for most indoor tracks in a truck. For recommended gearing and any stock motor you choose check out my web site for a gearing chart. Not all stock motors are to be geared the same. I do not have the Core/Hellfire chart up right now but gear the same as an MVP. (http://home.att.net/~casper04) If you are planning on some serious racing you will want to tune your Cyclone. The lower you make the drive freq the more punchy the truck will feel. You may also want to adjust the dead band and the minimum drive settings but you will get all this with the Millennium Pro if you purchase one of those (Great charger by the way!) If you get an older Cyclone you will need to get the older style cable for the ESC but Novak will send it to you for free. They ony have a Pitwizard cable for the C2 versions of the speedo. Hope this helps.

[civicds]

hey all. i used to own a xxx-t mfe truck but i sold it cause no one ran trucks where i live. Well now i found a track around my area that races them. So i'm gonna get a xxx-t mfe again. Any set ups would be appreciated. Also i will be running offroad and the track is huge with many tripples, doubles, table tops and woops. The turns are very tight and the terrian is loose dirt. theres some info you guys might need to help with a set up. thanks.

[vtjvt]

I just picked up a mf truck sunday, got it used from a friend, but the diff is broke where the balls go into the holes, can anyone recomend a online store to get a new diff or a kit to rebuild this one???

[dgrobe2112]

For stock racing.. any new motor works great.. I personnally like the Trinity Monster Horspower Pro.. if you get this motor you will need to gear 2 or 3 teeth lower than you would the P2K2 pro.. this motor is amazing..

As far as batteries go.. I have used the 3000 ultra metal hydrides with no problems at all.. very punchy all the way through the battery and plenty of life.. you can run 3300 if you want.. there is no rule against it anymore..

As far as set up goes on your truck.. i would try to fine out how the track conditions are.. ie.. bumpy, smooth.. dusty, tacky.. that type.. and you can use Losi's set ups on there website.. you can use the stock set up.. and go from there..

[civicds]

thanks. For batteries i'm gonna be running trinity vis-extra 3000's matched cells and orion 2400's team mathed cells. for a stock motor i'm gonna be running a revenge of the monster stock pro. the track is bumpy in some spots and smooth in others. the track i think is tacky i'm not positive. any more input will be appreciated.

[drumr racer]

hello all i just bought a xxx-t mfe didnt get it yet mail and was wondering if you had any tips on building it driving it stuff like that. and do you know of any ca that can be removed because i like the red rims i heard that paint thinner can remove ca but will it damage the rims:confused:

[drumr racer]

about the thing that a mf i different than a xxx-t spec we payied good money for the truck and its different:D

[bacaboy76]

All i have to say is that this is the best car that has been made. I started out with a rustler then i went to a rs4 mt then to a xxx-nt. After i had played with my xxx-nt a while i fell in love with team losi cars and buggies. Once i heard that losi was making a MF version of the xxx-t i had to buy it and indeed I did. It is a great car.

I do have one question though i have had a problem with my differential coming loose and I figured out that the nut was coming loose and/or stripping so i put a new nut on and it is still coming loose . if any of you have had this problem and know how to solve it please email me at bacaboy20042000@yahoo.com.

Thanx. :D

[olewarrior]

I NEED HELP FIGURING THIS OUT,I HAVE XXX-T MF TRUCK.I HAVE CHANGED TO SKIP PIVOT MOD,I HAVE ALSO PUT TRINITY 0 DEGREE HUBS ON IT.THIS THING IS EVEN LOOSE LIKE ON ICE ON PAVEMENT,GOD KNOWS WHAT IT WOULD BE LIKE ON DIRT.I HAVE REMOVED 1-WASHER OFF THE HUBS,IT HAD 2 TO START WITH,ON SKIP'S MOD I STARTED WITH 2-WASHER UNDER THE PIVOT BALL ON IT,I PULLED 1-OUT.THE TRUCK IS SO LOSE ON PAVEMENT I AM AFRAID TO TRY IT ON DIRT.CAN SOMEBODY PUT ME IN THE RIGHT DIRECTION,THAT IS ALL I HAVE CHANGED ON THE TRUCK AS FAR AS MAJOR PIECES.DID I OVER BOARD WITH THE HUBS & SKIPS MOD BOTH.HELPPPPPPPPPP!!!!!!

[drumr racer]

what tires are you running and you might want to check the caster and toe-in if your running stock tires,try running on a blue groove track if you can and post your setup

[Hard Core RC Guy]

I'm now proud owner of my own MFE!! Even if it's used on ebay, it's a fantastic truck, with almost all the goodies!! Making this my 5th RC in the collection, since I bought my Marui Hunter in 87'...since being back about 3 years ago I've now got the MFE, all is right in the world. Here's what I got!

MFE (obviously)
JR XR3i
IPC super sport

I'm racing stock, so along with the trinity motor it came with I have a Orion Core too!

So, besides tires. What's the next to functional hops??:cool:

[Gutter Ball]

I like the Trinity shock collars over the stock plastic ones. I've never had a stock plastic set that was easy to screw on without a wrench yet! Don't forget RPM ballcups/motor cover. If you're going to be doing some offroad with jumps, the Trinity aluminum front/rear pivots would be good to get. If you're really serious about racing, a lightened slipper clutch is a good buy too. If you're prone to breaking battery bars (I've never broken one, but lots of other people have) Trinity makes an aluminum one of those too. For occasional racing, the stock MFE is good enough.

[Hard Core RC Guy]

Thanks gutter, I haven't yet gone thru all the posts in here to see what other are saying. RPM equiped already. I'll look into the aluminum pivots. First thing I have to do, is convert all my batts over to deans (I was planning it anyway), and probably have to get some hole-shots for the track I race at. Later

:cool:

[teamlosiisback]

i have had my truck for two years and the only problem i have had was i broke a darn rear pivot block.

[Part-time]

Does anyone have a starting point for flat oval or TC?

Thanks

[SpeedMunkey]

I hate the snap on tie rod ends/ball cups. Does anyone make a ball joint version that fits the XXX-T? I've heard the Rustler set will fit, anyone tried em?

[xxxts.rule]

hi people im new to this forum :) ived had a few cars now a chadori tl-01 and a sprint. im now thinking of getting a mf xxxt. im only intending to use it for bashing and playing with my mates ao do you recomend it??? also are ther any alluminium parts for it??? do you think that the graphite will snap to easily in a crash???

thanks in advance

[Gutter Ball]

It's a good truck for the basher. Even though you're just bashing, the day might come when you want to race.

The aluminum parts I have: Front/rear pivots, shock bushings, servo plate, battery bar and shock collars. Not there for looks, there for strength.

As for parts breaking, hard to say. I've had head on crashes, massive end over end flips and hitting the boards with no breakage....but then a slight nudge (not even a nudge, more like a skim) on corner dot and the whole rear end falls apart :eek:

[xxxts.rule]

Hi gutter ball,
does this "but then a slight nudge (not even a nudge, more like a skim) on corner dot and the whole rear end falls apart" mean the chassis broke??? also what makes are the alluminium parts and is it a good jumper??? are there any reviews on the xxx-t (all versions)

thanks in advance

[Gutter Ball]

All my aluminum parts are Trinity. I have yet to break a chasis (knock on wood) on either of my MF's, but I have broken the rear T kick plates a couple of times. I like to get big air off the jumps (all or nothing, I'm usually not conservative on the jumps unless I don't get a good run leading up to the ramps), sometimes I don't land square and the rear end slaps down hard.

That corner dot incident was just weird, only because I just put a new kick plate and rear arms on and it was such a slight nudge. The plate snapped in half and both arms were broken where the hinge pin goes through. Perhaps there were flaws in the parts? :)

Jumping ability depends on set up and then throttle control after the jump. My truck jumps and lands nicely, my buggy on the other hand, still needs a bit of work on the setup.

Everybody keeps saying Losi's are fragile, but if you're constantly jumping off abnormally sized jumps, and hitting the walls/curbs/parking blocks, all cars will break.

I bought a Losi not based on reviews, all the fast guys were racing Losi when I got into RC so that's what I went with. Those guys were amazingly helpful with setup tips and spare parts. I'll admit it, mine broke a lot when I was a beginner. Out of 30 heats/mains, I think I managed to finish 5 or 6 of them my first year racing :p

Little did I know that Losi parts support at the LHS was non-existant :mad: because AE was more popular at the time. Now me and my pitmate are the ONLY people running Losi at our track, but we're 1-2 in 3 of the 4 classes we're running :cool:

Anyway, it's a good truck and I'll be sticking with Losi stuff for awhile. I have a MF2 on order too ;)

[xxxts.rule]

i like in the uk and looking on the sites i know i cant seem to find any spares for the mf edition xxxt or any other xxxt is this because of the mf2 ??? do you no any where in europe that sells xxxt spares???

thanks in advance :)

[dalejrfan8]

Hey gutter ball how much did you pay for the aluminum front pivots? I am intrested in getting a MF. I don't want an MF2. Its too much money.

[Gutter Ball]

The MF2 should only be a bit more expensive than the MF1. The MF2 is a waaaay better deal dalejrfan8. It includes the newer white ball cups (most people buy RPM ones), the rear pivot support is all aluminum, all hingepins have the titanium nitride coating, thrust bearings are carbide etc, unless you are buying it used. In that case, I've been seeing them on various boards for $100-$125!

I got my front pivot from Ebay, I think Trinity wants $30+ for it and I got it for $10 brand new.

Not sure about the older XXX-T parts. Most of the parts are identical and my guess is they're going to stop making the older version of the arms since the new ones will work fine on both trucks.

[dalejrfan8]

I was planning on buying it used, but I just found out my lhs doesn't stock losi parts anymore.

[winning edge designs]

Wow, no Losi parts in a real hobby shop? That's strange, i'd check someplace else. Luckily there are tons of sources for Mail Order parts, kits, etc. Try Superior hobbies dot com out of Florida.......Any real shop should let you decide what brand you like, Superior carries parts for all brands, not only the one thier sponsored employee runs for!......I just put together my XXXT MF2, thing is really done well out of the box, even better ball cups, new trans, very adjustable, etc.........Jim

[cabbynate]

will be racing my MF2 today for the first time. Mod truck on a step-pin track.
I'm starting with the kit set up with pink steps and gold directionals. I also went with 1dg anti squat instead of 2dg. It's got the Trinity rear hubs with 3 gold washers under each ball stud. I also used ceramic balls in the diff and Acer's ceramic outdrive bearings. My kit did not come with the window mask but it's on the way from Losi so next week I will get to try out the new body.
I'll you guys know how the truck works for me. Wish me luck...... ;)

Raced the truck and the set up I ran worked well. I don't think I'll change much more. Different tires for different tracks and maybe rear springs and oil but that's it. I realy like it. ;)

Hi

Got my MF2 last week in the mail… I was a happy camper. :D I normally run nitro touring cars so this is my first electric stadium truck….. took it out a few times and ran great…. I got the Novak 5800 Brushless system…. I never knew electric could be so fast.. wow!!!!

Well I have a question about the transmission which seems a bit more complex to build than what I am used to. I finally took it to the track over the weekend end and I completely destroyed my transmission. The gear diff is gone….. basically the 12 carbide balls ripped the plastic so the whole inner plastic of the gear dif melted away which left me with lots of balls in my transmission case. What did I do wrong? Was it too tight? Was it too lose?
:confused:

I followed the directions: I put the female and male drive together…. I slightly threaded them until it was snug. Then by hand I turned them 4.5 times by the time I did this I could not turn the gear when holding the outdrives/Diff halve…. So I turned it 2 turns more….. took It out and I guess it felt right….. Actually it was really tight and a little worried about the “Diff nut” …. Its plastic tabs fit into the Outdrive/Diff half…. I am afraid to add too much force on the screw and break off the plastic tabs…

Thanks for any help !!!!!

The diff was set too loose. When you are assembling the tranny, just put together the diff and tighten snugly. The actual diff adjustment is done AFTER everything is completed.

To check the diff, first tighten the slipper clutch nut all the way down. Hold the spur gear with your right thumb while holding the right rear tire. Try to turn the left rear tire. If it turns easily, your diff is too loose. Tighten it as described in the back of your manual (by the way, this is all in the back of your manual, so just follow the directions back there). Tighten the diff until it is extremely difficult to turn the left rear tire. After you are done, makes sure to reset the slipper clutch.

After the initial assembly of your truck or after a diff rebuild, the differential will tend to loosen up and its first couple runs. You need to check the diff after the first run and second run to re-tighten it.

I usually check my diff every raceday before I start practicing and then before the Mains. I'm just paranoid I guess. :D Have fun with your new MF2. I know I am!

[winning edge designs]

I would re read thur the manual for diff assembly. alot of people(me included) like to rip thru and biuld thier kits fast. The notes thru out the instructions tell you about readjusting after a couple minutes run in of the truck. I set my diffs tight, for run in, then after running about 2 or 3 minutes recheck my slipper and diff settings. Usually the double disk slipper works so well it can overpower the diff if run too tight, no matter how tight the diff is adjusted.....Always check your slipper to see it slips before the diff, no matter how you adjust your diff........, Jim

[Carajo]

Thank you both for your ideas....... I am such a dork i didn't even see the end of the manual with the tips and hints for the Diff and slipper.... :eek:

I should get my spares in the mail by tuesday (I hope.... ).

I have to say with the small time I had to drive it I feel in love with it. I was really surprised how responsive the steering was during high speed. The truck itself seemed to float around the track.

My poor nitro touring car is just sitting there on the work bench… I only wanna drive my MF2!

Again thanks for the quick help!

[cabbynate]

Yea, sounds like the slipper was to tight. I did notice that the new spring required more adjustments as the race day went on. I think it will seat in after a few more runs. I heard the new spring needs to be broken in and after that it really works great.

The new trans/diff is a bigtime improvement. I have run my buggy(BK2) without touching the trans now for over 40 batteries! The diff is still silky smooth and doesn't feel like it will need a ttention for quite a while.....The truck, while harder on diffs like all trucks, should still be similar as far as the improvements go. Lower maintenance is always a plus!........Jim

[cabbynate]

I also think the new trans/diff is an improvement. The tranny case is slimmer so adjustments are that much easier and the gear ratio seems to spool up quicker.
I put a piece of chassis protection tape along the seem of the tranny case at the bottom to try and keep the dirt out and also spare the case the abuse of dragging the ground after some of those hard landings.

How are those outdrives holding up? 40 runs and minimal wear would be nice!! :)

[winning edge designs]

Cabbynate, yes, my outdrives are untouched as far as chips, or serious wear goes, holding up very well.
To seal my trans case, I use a bit of white "assembly lube" on the halves before assembly. Wipe off excess after snugging case bolts.....This keeps even the smallest of dust from hurting anything inside. I also use just a tiny bit of diff grease on the idler gear, 3 or four small dabs, during assembly. Some say not to do this, some think it's the best.....But I am getting a full year out of my trans gears, so i'll continue doing it....Jim

[cabbynate]

W.E.D,
Glad to here that the outdrives aren't wearing fast.
I also use the white grease to seal the tranny case. I use I use Aero-Car Hobby Lubricants Super Speed Gear Lube where you use the diff grease on the idler gear. The gear lube I use doesn't cause any drag at all. I have to keep it refrigerated so it won't melt. It's like a very lite wax.

Hi guys, i own two xxx-ts (older versions). I was wondering if losi part support will still be there for the old version? I love my trucks. Outdrive wear and tranny wear on my car running brushless is minimal, been running a good 8 months on the same tranny gears, just rebuilding.

[Racin Rev]

I will be aquiring a mf2 in the very near future and will be running a novak brushless in it. what would be a good starting spur gear for that combo? Thanks!

[alexrckid]

anyone know what losi springs are used on the MF2???.....also, what weight shock oil(font/rear) and pistons are used...???..thanks.

[winning edge designs]

Not sure on any brushless ifno ,since thye aren't legal in my are yet.

for set-up, the MF2 comes with red springs and 30 wt, using 56(pink/red) pistons all around. I am using 35 wt front, 30 rear, 56 pistons. I also went to the #4 rear tower position and moved my rear camber link to #2-B. Everything else was left stock, seems awesome so far!.....Jim

[Racin Rev]

Jim, What kind of track are you driving on? and what notable difference do your changes make?

[gizmoguy303]

Start with a 18 tooth pinion and the stock 86 tooth spur gear. That will get you in the ball park.

[gizmoguy303]

I am running a version of Adam Drake's standard setup (located on Losi's website). It uses the blue buggy springs. It's dialed! I highly recommend trying it.

[winning edge designs]

Racin' rev, my set-up changes stopped the rear steer my truck had. I am running it on a hardpacked surface, with high bite. We run M3, or Losi Red slicks all around. The truck wanted to dump in the rear and seemed to want to break loose a little. The shocks being moved out on the tower and camber link change helped a ton. I may try orange springs(all 4) next to get the truck even more responsive....Jim

[Racin Rev]

I was wondering if anyone else out there has had my diffulculties. I have a new xxxtmf2 and am trying to assemble it. I am not new to this I had an original xxxnt before the rtr and drake (still have it), a tc3 hyper 7 other cars. I have done all the stuff with them. but with the mf2 i have had problems.

I have rounded off the two longer screws which attatch the front suspension to the bulkhead. I was using associated allens, which i have generally found to be pretty good. they were not case hardened (another guy with one got his with case hardened screws.) I have used the thread cutting screw in all cases, yes, i know, i should get a tap but this should work anyway. Losi is sending me new ones. one of the button head screws which holds the motor shroud to the tranny rounded out again associated allens, replaced with an associated tc3 part, no problem. Then, i have had problems with stripping out the shock cartriges. The first one stripped enough to be unusable I had a take off from my xxxnt and put it on it stripped too but when i got to the seat it straightened itself out (i hope it doesn't leak). 2 of the four shocks had problems, one front and one rear. I tried to do a dry run on these without oil just to see how well they screwed in but had problems there too. I have rebuilt shocks many times on all of the various cars i have owned including the xxxnt (which is a hi miler) never with any problems. one of the shock collars had a piece of debries under the o ring about 1/8 inch around. it was easily detectable by looking at the distorted o ring and it fell right out. Why couldn't the assembler have spotted this? has anyone else had these problems? Is qc at losi slipping?

[cabbynate]

My only complant was a out of round spur gear and bad window mask.

[Racin Rev]

I forgot all about the window mask.

[redsixer]

The only problem I had was screwing in the ball stud in the front shock tower. Is there an easy way to do this?

[Racin Rev]

I have some old hpi 4-way wrenches. one of the sides (the short side) works perfectly.

[winning edge designs]

Quality allen tools will help, but you'll still need to "Pre-tap" the bolt holes in all locations. I also use a tiny bit of the white "assembly grease" during the initial kit assembly.

I have occasionally cross threaded a shock cartridge myself as well, even after biulding hundreds of these R/C cars for about 20 years(Tamiya Fox was first in 1985). If the shock cartridge gets forced in too far, it will be destroyed, but I've caught myself a half dozen times and been able to reuse them more often then not.

As far as the shock collar having debris, it can be missed after doing hundreds of them a day, I suppose. It also could have picked something up afterwards, but not likely. I always inspect every part before assembly of any kit because of the potential for this to happen. I have gotten tons of screws without any threads, from every company(except Tamiya)even ones with threads in a circle and not able to thread in, haha. The important thing is if the stand behind thier product, which TeamLosi is top notch in that department!

Good luck the rest of the way!....Jim
