I have wound 12 pole outrunner motors quite high with direct to diff configuration with NO problems using the Quark 125 Monster Pro. 12 pole motors require twice the switching per revolution as a 6 pole motor does. I've wound the 12 pole motors up to around 25,000 rpm's. I don't think the Quark switching ability is the problem really.

After taking another look at your setup. You have quite the Battery configuration there. It can definately deliver. Just guessing, 220 amps continous, probably somewhere about 300 amps Burst rating.

Ok, with that being said. Mega only recommends winding their Mega 22/30/1e to around 44,000 rpms and only rates this motor up to 12 nimh cells or 4S with a current draw of 70 amps max. On 6S, it's going to spin 63492 rpms and will definately overheat very quickly even with dumptruck gearing. I can only imagine what the amp draw is doing with the tall gears, especially on take off.

I would try 5S with lower gearing, like Linc said. Then maybe, just maybe, move up to 6S, only after being comfortable with the temps you are seeing on 5S.
