I did manage to get the MM hot this time. It's a bit heavier setup and I had no cooling hole in the body, no fans, no extra caps... and I was pushing it pretty hard. I got about 10 minutes in and it cut out a couple times for like 5 seconds.

I pulled it off so I didn't have to have the marshalls keep grabbing the car. I was up to 4th place at the time...

It only temped at 185-190 on the heatsink... it's been much hotter before without thermalling so I'm still not convinced that's what was going on. But that's the most likely thing. I think the motor was in the 160s. Normally the esc also runs about that.

...

If I had caps or better cooling for my MM.... I likely would have finished 3rd.
You sure it was the ESC? I had a very similar thing happen with my Hyper8 and it turned out to be the receiver rebooting because of the cheap UBEC I was running. Switched to a CC BEC and the problem went away.

BTW, can the CD take a Kyosho 46T spur? Might help temps a bit.
