I have the lst nothing but problems.the truck will sit there and idle awesome but when i give it gas it revs up real high and the wheels are not turning as fast as it revs the company has sent me 3 owb anything else u can think of for me to try thank you for yo help

Check your engine alignment. and while your engine is out look at the clutch bell and see if you can rotate it. there might be blown bearings or clutch shoes.

+1 for that.
try, can you push it on the ground forward and backword, when you do, do the wheels turn freely and spin the spur and clutch beel spin? also have you rebuilt the diffs, your diffs might be backwards, that maybe 1 of them. idk try what i just said and reply back with progress

never had diffs rebuilt the truck when we bought it was new its a year old and only have about 7 tanks thru it cause it keeps doing this crap took clutch bell off was some black residue in clean that will post back later and let know what happen

Were there any bearings? they might have blew out, if they were there were they still silver or were they black? dented clutch shoes? broken?

the black res is res from the clutch shoes probably. but can you push it on the ground?

sounds like the slipper to me. W/ gear cover off, on the gound, see if the the large spur (1st gear) spins under throttle. If so, then it's the output shaft in the tranny. I sheared one leading a RC ProSeries race!!

tighten the slipper all the way and see what happens, make sure all the spacers, slipper pads, brass bushings, etc. are all seated properly. Hope this helps.

+1 want Hempy said.. also the Lst2 has been known for broken pins somewhere in the drive line. not sure where, but get ahold of Brentmorl on here, as I know he whas one of them, and he started makeing his own pins out of titanium drill bits..

the pins i have problems with or i should say had was the pins in the diff. but if the truck moves its not the diff but if you tried all check to make sure your fly wheel is not slipping on the collet thats probally what it is it may feel tight but pull the clutch bell off and make sure the nut is tight,tight,tight id it was lose id spend a dollar and buy a new collet as well....i would almost bet thats whats going on

I agree. If it was the one way, it would only engage intermittently. either the flywheel's slipping on the collet, or oil on the clutch bell.

you guys are giving me some very helpful info and i thank you all for it.I just replace 1st and 2nd gears new clutch bell gears cleaned all slipper pads and it works now thats so awesome now i need to get the right shim spacing on clutch bell now for some reason i can't spin the bell freely and losi tech said it was the bell shims when i start it wheels have to be off ground cause it turns them

Yeah, you better get yourself an OFNA shim kit quick. The clutch bell needs to spin freely. When you spin it, it should keep spinning for at least 5-10 seconds.

all shimmed up and runs pretty good sucks its cold can't tune n cold you guys and or gals in this forum are awesome thanks alot

sorry i just saw this thread, a little late, i had the same problem. the solutions is to go to the center drive shafts on the bottom of the car and tighten the set screws, when tightening them use blue loctite if you have any questions please post.
