I thought about trying this. Maybe it's my next step.

IDK about anyone else, but 3 burnt ESCs between 2 cars, 2 motors and 2 batts says something is seriously wrong with the setup &/or driver.

On the trugg, your FDR is nearly 20:1, that really really low for such a powerful motor like a 1515. Even with that hot motor you should be somewhere like 15:1 as starters. That puts you at 50ish mph and 150A at least. You've tried to gear down for a reasonable track spd, but a motor's efficiency dies if the motor is not properly loaded. Low eff, lots of heat. That may be a big factor. If things are setup right, you won't need all the fans and crap nor a swiss cheese shell. FWIW, RCM Mike runs a 2.5D on 5S, and I had a 2y (1100) on 9s A123 (about 28K rpms too) and both have plenty of power for the track and no crazy thermalling.

Also, the way you drive may be contributing. Do you stab at it like a nitro? How aggressively are you pushing it? That may be something to do with it as well. I hope a cap fixes it, but IMO you have probs beyond what a cap can do.
