I'm gonna try the new SC HV4.5 motor with my old GTB ESC. Anybody see any problems with that? I will be putting this in a Slash 4x4 PE. Not sure what pinion to start with - a 12 maybe? This would be for racing on a fairly large track. I need to stay up with the Jammins running the 4.5s.

Gotta try something - the Velineon with a 16 pinion comes off too hot when trying to stay up with the HV4.5s. Normally low 190s after 5-7 mins - can't even run any practice
