RE: Hmm this could be bad.
You will need to make sure your running a 25T pinion and a 55 Spur to Avoid Burning the motor out and it will no longer be suitable for Drift but for Racing.
Brushless is Way too much over kill for Drift.
We Recommend no lower then a 17x2T for Drifting purposes with a Tamiya Sports Tuned OR a 19x2T as the Ideal Combo on the Stock Spur..
