Hi, I have a TLR 22 2.0 since new 12 - 14 years ago. I recently gave it some love and have been testing it on the street in front of my home.. The problem is when I give it the beans from a start it immediately spins out. I've tried 5000 cSt & 15,000 cSt weight diff oil and I cannot get it to stop spinning out. It also does the same thing when I give it full brakes at speed. I would appreciate advice on how to stop this. I want it to just go straight when I juice it from a stop. I've tried it with the ball diff and the gear diff..
It has kit slipper. I've tried all kinds of adjustment with the slipper and none of them work to solve the spinning out problem. I've tried the mid and the rear motor configurations The car has all the usual aluminum upgrades from that era. Please advise if you can.

Sounds like it belongs here: https://www.rctech.net/forum/electric-off-road-4/

It's not a RC Tech site issue after all...

Though that since it is 14 years old it belonged here.
