wanderer 12s gearing

[James]

I have a 12s wanderer on a associated t2 and 12 cells, and it geared with a 65t spur,and a 18t pinion. After 10 minutes the motor gets so hot that if i touch it for like 1millisecond it burns my finger. the esc doesnt get hot at all. what size pinion should i use.


Also i thing i have the slipper to lose, but i cant tighten it anymore. WHen i accelerate hard, the motor spines really fast, but the tires dont spin very fast, and it makes a wierd sound. It took me about 250ft to get it up to 35 mph.
