Just ran my muggy today. Had to stop after about 15 minutes because a rear susp.arm broke...

I ran it with lutach's 10s esc on 8s and a medusa 1300kv 60mm.... geared 12/48 (approx.40mph). Outside temp was 26.7f / -3c. I have a spektrum dx3s so I measured the motor temp with the telemetry function and according to the dx3s the max motor temp was 113f / 45c. The muggy weighs 12.3lbs / 5.6kgs.

I really love the way this combo handles the muggy. It does wheelies from startup, doesn't wheely much more after that. Very controllable power.
