New Jammin crt .5 motor question

[GO-RIDE.com]

I'm a bit surprised that your MM is heating up with just a 15T on stock buggy tires. The rule of thumb is (Hot ESC and Batteries + Cool motor = Overgeared). How's your battery temp?

I run my E-CRT.5 with Novak GTB & 6.5 setup at our local indoor track and my buds large back yard track. I definitely pull a good bit of throttle throughout the track, but not the same as WOT speed runs. Mine can get hot when it's over 90 degrees outside and I run the 2.2 truck tires with the 13T pinion, but otherwise it runs great. I'm certain I don't have nearly the torque that the Medusa has, so I'd expect the Medusa to pull that 15T easily.
