Please could someone point me at the sticky re gearing and temps

[Arct1k]

Trying to balance blowing up MM on 4s (I think due to cogging) and high motor temps.

I'm going to try direct soldering the motor leads but when I did my last test run motor was V hot to touch esc was cool...

This is for my MBX5 (MSR T) i.e. buggy diffs - 16/46 on 9XL 4S with MT Badlands.

I thought hot motor / cooler ESC was undergeared... It feels quick but not this quick...
