Another place you may be losing power is in the gearbox/motor setup. If your motors, or some gears are slightly misaligned, this could cause a lot of friction and hurt your power output. I would test the current going through your drive train motors when the wheels are free spinning and compare that the the cim motor cure. If the current is high, this would indicate some resistance in the drive train. We had this issue last year, and a little bit of tweaking made a big difference.
