try adjusting ur controller on the servo I have that prob. on my tao3 then tweek the steering adjstment on the controller it done now

the problem is the diff lock it up by putting blu tack, cardboardor shrinkwrap sumthing to jam the gears. it fixes the problem iv done it to many tt-0's , u can also do this to the rear differential but sum ppl like it sum dont personal preference . but deffinatley lock the fron with somthing

locking the front diff? really?
i was under the impression that if u are going to lock ur diffs.. either lock just the rear or lock both.... but not just lock the front....

It's not a radio problem... if you adjust the radio then the car is either going to oversteer one way or understeer bothways.

well u lock the rear diff u will defiinatley get this problem, somtimes the problem just happens standard if u are just locking ur front diff just use bluetack or sill putty so it gives it a L.S.D effect. differentials and 4wd are the onlyt differences between real drift cars and rcdrift cars
