What's the best neu on 6s in an e-revo ?

[speedy]

So a bl-motor with lower kv doesn't have more low-end tq ?hmm i've winden a lot of cd-motors for airplanes and the ones with lots of winding turns was alot stronger than the one's with less winds ?

I mostly bash my e-revo ! So the motor scould be made mostly for bashing ! and i whant it to run cool for a longtime like 20-40min's ! How big lipopacks do i need to get 20-40min's runtime and maby 45-50mph topspeed ?
