4s in a TC3

[lutach]

I did speed runs, but not 5 minutes worth. I changed the Trinity N80 in favor of a Novak 5.5R using a 35T pinion and 72T spur. I will also try a 69T spur later. I'm only using 2S lipos and I've been able to reach 50mph+ with the N80, 32T pinion and 72T spur. I have 2 new ESC and a 5.5 motor to try out. Both of this units can be run in sensored or sensoless mode. The Hobbywing ESC can handle 4S lipos, but will the 5.5R motor handles the high RPMs? The rotor is wrapped with Kevlar.
