anyone running mm 5700 in .5 crt?

The motor and ESC gets too warm from my experience, and that's with a 12T pinion, stock tires, and 2s lipo. If you do plan on running this setup, I would see about getting a smaller hardened pinion, like 11T.

And/or, add a heatsink to the motor and put a fan on the MM. As a rule, I never recommend fans, but in this case, I think it will be the only way to keep everything cool.
