Well finally got to give it a test at my local track.
Ran for 24 minutes until the Motor got up to 155F and shut it off. Battery was 95F and the ESC was 110F. Fan still works on the MMM and had to problems with it at all. After it cooled down went out for another 5 minutes on the same battery but the battery holder (gorilla) snapped
which sent my lipo flying & flipping accross the ground and ending my day
Heard of alot of guys having trouble with the straps snapping but would of thought it would of last longer than 29 minutes.
