I also have another MGM22418 that I run with 6S flightpowers, 1515 2.5D/F, 16/51 gearing in a HEAVY all aluminum Emaxx (big honkin MT beadlock tires & rims too). Zero cogging and temps are well within acceptable limits-quite cool actually.

I have not experienced-knock on wood-any problems with these ESCs...I think there has to be other issues that caused your problem.
