You probably need to gear down and/or use lower traction wheels. We are running on dual Andymark wheels from this year's kit, with 12:1 reduction in our transmission, and 15:36 sprockets from the transmission to the drive wheels, with csingle CIMs. If you are six wheel drive, the center wheels should be lower than the front/rear wheels by about 1/4 inch for easier turning. Compare your drive ratio's to ours. Too much traction, or too high a ratio for speed, will pull more amps and trip the 40 amp breakers. You are using 40 amp breakers, I hope, to the CIM's ? PM me if you have any further questions.

My thought was that maybe 2 victors weren't enough to push our bot and the CIMs were being over-taxed. The bot weighs 119.2 pounds(without batteries) We are using a two wheel center drive system, 1 motor per wheel using standard toughboxes with direct drive to the wheel (no further reduction after the toughboxes). Would adding another CIM to each wheel remedy this situation? Thanks alot!
