Well the best brushless motor for drifting would probably be the NOvak Super Sport the Tekin Super stock burshless motor there coming out with soon will probably be good too. Anything more powerfull then that would be too much for drifting. just so you know you arent gona get a ny performance gains in getting this set-up over a quality motor. 27T motorsd rarely need maintence anyways, so the only thing youll be gaing is being able to skip the little amount of maintence a 27T motor needs. If you wanna get a brushed motor. Probably the 2 best (there are other good drift motors, butalot of people agree these are the best) are the P2K2 PRo, or the Co27 PRO.
