Im also using 2.2 truck tires. Thank's

Does your MM currently get hot? With a lot of guys running 4S in 1/8 buggies and truggies through a modded MM I would think 2S and and S can motor in the little crt.5 would be no challenge for the MM? If only your MM is getting overly hot have you considered a small fan? I know a lot of guys don't like them, but mines lasted for months in my crt.5 and i've broke about every plastic part there is on the truck.

I'm kind of in the same boat, but I'm looking for a motor with more torque than my Novak GTB/6.5 combo. My combo has a kv of 6400, but runs cool at the track geared 12:46 and truck tires, or 13:46 and buggy tires. I'd like to get MM & 7S or 8S, but I don't want to give up top speed if the Feigao can't turn a much bigger pinion. I think ultimately I'll wait a bit till I can justify a MM & Neu 1506 (5500kv).
