With brand new treads, and with an even faster gearing on our arm (I remember the FP getting HOT to the touch during practice - we increased the reduction in our competition bot so that it barely gets warm to the touch now).
All the math, intuition, and experience says that the problem is drawing too much current. But I can't figure out why, for the life of me, we didn't have any problems until midway through the regional.

I was really putting MOEhawk up as the lesson for extreme testing before ship, not your current bot. We finally got MOEhawk all together (we tested components before), ran it at half speed into the 3 goals and said "Ship It" (it was getting late). Question on your testing, are you simulating defense with an old bot (high speed collisions and pushing matches)? If I remember FL well enough you were seeing your share of D and tended to fail later in matches after everything got hot.
I am always amazed how Team 25 has so few over current issues with their drive train (they had a few notable ones early like on Einstien '03). They have mastered the 4 CIM fast single speed with 6-8 Bead-LOK wheels on the floor. It has to be some combination of good driving, gear box efficiency, and good use of the brake pin.
