XRAY - Model racing cars

i race indoors on carpet with t3 last club night car was undriveable when on 50-100 % acceloration would just spin out from rear and do a 360 tyres are new people from club came to help saying rear ball diff was to loose and slipping tightened up but came loose again straight away borrowed a rear ball diff from a mate at club night car was still doing the same all through the 4 heats car was checked for tweak and camber etc but still made no difference when i got home stripped car down found one of the front axle driveshaft adapters was loose on front solid axle tried to tightened up but screw thread was no good so i have ordered new front solid axle and rear ball diff will these sort out the full power problem of spinning out or can it be something else ? thanks for any replys

check the wheel bearings , all the drive line for binding and make sure everything is overhalled , i would re build the whole car looking at all the small silly little things just in case .

It doesnt take much to upset one of these cars ,

Good luck finding it and let us know what it was when you find it

i think bearing on right or left side are NOT runing smoth
change them

Hopefully the new spool will cure your problems. But be sure that the drivetrain is moving freely throughout, rebuild and re-grease driveshafts, and check bearings for smoothness. Also be sure to check your tires that they are perfectly glued and true. You might want to try another set of tires as well. The diff should be tight and smooth.
