As a suggestion, 1 CIM per side without a shifter and with anything approaching grippy wheels is probably going to be a stretch to keep from over working the CIM or the Jaguar (or Victor) or (most likely if you fix the other problems) the 40A Breaker.

I suggest you buy two CIM-Sim from AndyMark or a CIMULATOR from Banebots and use one of the excellent 550 motors that are legal (one of the many FP motors or Banebot 550 motor... -- in general the more power the better) and buy another two Jaguar or (better yet, given my GAH!!! in the message above) two Victors.

If you install this on your CIMPleBox in parallel with your CIM you will have more power to turn but more importantly in your case, you will have two current paths -- and since loses are an I^2 R problem, halving your current can effectively quarter your electrical heat dissipation.

And, as long as you can wire up the speed controllers & press the gears on at the competition , everything is COTS so it doesn't count on the 30lbs allowance (of course you still have to make your 120lbs limit but one battle at a time...)

Wishing us both luck...
