Re: What wheel to use for the flywheel

Our initial prototype used the 4" traction wheels that have come in the KoP in the past (very hard). It worked well enough, but even with only a moderate amount of compression you could hear/see the CIM motor powering it practically stall when a ball went through. Switch that out to the AndyMark compliant wheels, and now with the same setup (same compression, same motor, same gear ratio, literally the only difference is changing one 4" wheel for another) we can feed in a whole row of balls without any noticeable slowdown with the motor. The compliant wheels really do make a difference.
