Thanks guys, I went racing this weekend but couldn't convince myself of running this body yet.

I am wondering after this weekend's race. After a 15 minute main, running Neu 3900 mah 4S in parallel, geared for 40 mph, My whole system was pretty hot. Motor 185, ESC 165 and batts 130. Ambient temperature was in the mid 80s, I have holes in the body for ventilation. The track has a new layout with two long straights that lets the MMM breathe almost to max rpm. Could it be that the CD, which always unloads to the front a bit more to prevent wheelies, puts too much strain on the system because it revs too high a lot of the time especially if the CD unloads too much in certain parts of the track? Because of the loss of traction due to the CD unloading, I think more throttle input is applied trying to get the same amount of acceleration as with a solid axle in the tranny. Does this make sense? I know my gearing is fine, I absolutely know that my drive train rolls very freely with no biding anywhere.
I seriously think that with the MMM's torque, a CD may not be beneficial and a solid axle with better throttle control might make me faster with lower temps and less strain on the MMM and batts.

What is everyone's take on this?
