have you checked out the
speed calculator?
im gonna run a 2200kv MMM motor and 5s lipo in my hyper geared 14/46 and i should get it up just above 60mph and should have cool temps...
5s on 2200kv puts you at 40480rpm which is like perfect
i wouldnt use the other nue motor, id stick witht he 2200 if you want it to be faster and crazy for bashing :) altho it probably would be a huge difference, only 200kv
