Last weekend I had my first run with a MMPro in a Slash 4x4 with a 6 pole brushless motor (1530kv @5s). I have it setup for the same speed as a stock Slash 4x4 on 2s. After 30minutes of bashing the motor reached 44c and the MMPro was 15c.

The setup needs some fine tuning in timing. The manufacturer recommendend 5 degrees timing, but on forums I've read that 20-25degrees timing is best. So that will be my next attempt.
