mm + 4600 motor temp near 200 with rustler

[MetalMan]

Have you by chance tried a different battery combination? If not, it seemse it's the only thing you haven't listed.

13/90 is quite undergeared - that's a theoretical 26mph, and the motor's going to want to push out at least 35mph on that voltage, which would be with an 18t pinion. But since you tried pinions around that size, I just don't know.

How about timing on the ESC?
