The c50 maxx is a good 4s motor, not sure if I would try 5s, but at 50 bucks it is not too expensive. Do not use this motor without a slipper, as the 1/8" shaft will break. I broke one shaft in my hyper7. The shafts are hardened, and quite brittle, I even tried to weld another piece back on and have it machined, but that did not work either. Tekno sells a 5mm upgrade shaft for $75, that plus the $50 makes $125, still a good deal for that motor.
