Mr Wilson, I must say, you have some very nice looking buggies.
as for the caps, I've been running one novak 2700uf cap per esc my MM's and they reduce the heat by a good 20* F. I have two set-up this way and two that are not. The two standard ones only run 540S size motors and still get hotter than the modded ones running Neu 1512 motors.
There's two sides to every schwartz, he got the up side and I got the down side.
