zxavin is right, a HPI Sprint 2 would offer you a Better drifter then the nitro RS4... but if you want to stick with Nitro sliding, ABS Tyres are too slick causing the Nitro motor to over rev causing a really bad Head crack.

Whilst nitro's are OK at racing, drifting is done at alot lower speeds, you will need to run the motor rich just to keep it alive..
Also be prepared to go through Clutches and Brake pads like no tommorrow...
