Re: drive train wearing out?

We had that SAME EXACT problem with our drive train. We used a direct front wheel drive 1 CIM per side configuration with traction wheels. (We had omni's in the back) Our issue was we would test on our hard linoleum surface and be fine. We also tested at the play date. We were fine (but we only ran one match per trial). We got to Chesapeake and nothing worked. If you use a Gyro, disable the gyro code and any other sensors that would affect your drivetrain. These could be hindering your turning ability because they attempt to control the spin and causing you to be unable to turn. When the motors are cool, I bet you have decent performance. As motors heat up, the become less efficient causing more power to be drawn. Did you ever notice a "stuttering"? This would be caused by circuit breakers popping and resetting. If possible, I would strongly consider changing your gear ratio or between matches putting ice packs on all of your motors. We did this with great success at Philly and I think it can work for your team too!
