Greetings,
Try using 4 of the previous years traction wheels. Two by two really keeps the ball cruising and helps pick them up out of whatever hopper you have to store these things. I agree that the CIMs should not be used directly, as we had some trouble today. A geared or belt system running both sets of wheels will keep them spinning at the same speed and at reasonable speed. Direct drive with the CIM motors could clear 15 feet in our test, but that just bounces of the center post in the trailer. Good luck!!
