RE: Problem drifting
Inspect your car, look and see if the Hex pins are all in..
You shouldn't have a problem at all drifting a TT-01 with a locked Rear diff as that already is the Ideal Set up for a TT-01..
I think the Rolling Slide start is more appropriate.
Use Half throttle, then in Quick Succession, Turn and apply Full throttle... this will up set the rear of the car and Get the car's rear end out with out having to Scandanavian flick it... once the Back End Starts to slide out, pulse both the throttle and the steering rapidly to control the slide...
If Your having trouble getting it to turn, back off the throttle then instantly re-apply.. this should allow the car to re-gain grip then loose it again..
