I thought I had turned the startup power up but I guess not, I did try increasing the timing to 15deg. No motor temp issues(105f after sitting a few minutes), but the ESC was peaking at 150f several minutes after a 10 min average bash session.

I just installed a small fan I harvested from an old laptop. Might need a larger fan though this one really doesn't seem to move much air. I hope just having constant air flow for the ESC will be enough.

I was running the 15/68t combo, I dont have a 16t pinion but I do have 65 and 62t spurs so I can hit a ratio either side of 16/68. If I can get the ESC temps down under 140f I will try some taller ratios, I'd like some more top end.

Is that MMM shipping yet
