As the man says a 3T for drifting is overpowered to the point of being useless.
I've tried various motors in my drifters from 5.5T brushless to 17x2 brushed.
Best motor so far is the Speed passion V3 13.5T
With the XeRun Esc running in supercharged mode i've got great control through the rev range then that extra kick to get me out of trouble if i need it.
Cheers
