on seths note i recomend that for drag racing you almost lock your diff. i am not aquanted with the rustler but if it has a ball diff setting it very tight will give the car a kind of posidrive that will make it accellerate very straght and true even when wheelspining.

secondly a drifting gyro helps keeping a car from spinning out when draging if you loose traction for example i could keep on the gas constant and the gyro would correct any rotation of the car and keep it true even when wheels were franticly spinning.
