My brushless HPI Nitro MT Project

Those temps can definitely be attributed to gearing. Using a smaller pinion would do the trick, but it's understandable that you'd rather save $12 if you can help it.

I'm going to try 52/13 with the dirt hawgs tomorrow and see how bad it is. Then if that doesn't work, 52/13 with the road rages. The motor got to 168 last time with 52/15 and the road rages, which are much smaller than the dirt hawgs, which is why I wonder. That was mostly full throttle on pavement though so we'll see.

So I tried 52/13 with the Road Rages:

~90 ambient

After 6 min of running:

ESC: 140
Motor: 145
Batteries: 130


After 11 min of running:

ESC: 165
Motor: 167
Batteries: 137


It can't possibly need to be geared any lower can it? The ESC is doing better but the motor is still struggling. I don't know what the next step is except some good fans. Maybe it's just too hot out? :confused:
