need new clutch?
 

I have a Losi xxx RTR 1/10 Nitro....My question is I ran Approx. 2 tanks of gas through it and now it will rev but not move....I checked the diff and it seems to be tight, but I rev the engine and the gears dont move just revs....Need new clutch? please help....thanks :flaming:

Did u try and remove the clutchbell to check if maybe the springs are broken?

springs are not broke just took it apart

check your slipper adjustment also. also if you didn't follow the instructions on setting the diff. after the very first run or you overtightened it you may have melted the diff gear itself. you will need to take the tranny out and look at it. means fully disassemble the diff. it will be obvious if it is melted at that point. since your in there i strongly recommend you go with the aluminum diff gear.

As above.
