XRAY - Model racing cars

when i put the throttle onto the car the car goes into a rear end spin. i am running on carpet any ideas to sort this

start with wisbones check they fall freely under own weight and the work you way through rest os suspension look for bent hinge pin, bent shock shaft, basically anthing which could cause suspension to bind.
Then check shocks should be equal lenght, droops etc should be equal each side.

hope that helps
