We followed the directions on how to assemble from the website..

Bob, we're running the same ratios as you using the AM 9015 motors. We had some binding issues initially too. I emailed Vex and got an immediate reply from Paul Copioli with the very helpful technique to loosen the mounting bolts slightly and run the motor. When the motor and gearbox sound like they're running smoothly tighten the screws. That technique solved our binding issues.
By the way, if anyone else is using a AM 9015 motor from this year's KOP with the VerasPlanetary you'll probably need to use the 1/4" spacers with any gear ratio as the knurled length of the shaft is shorter than an AM 9015 motor from last year. Paul said they designed the AM 9015 collar to grip the knurling, but with the shorter knurled length it's trying to grip an un-knurled portion of the shaft. The 1/4" spacers put the knurling in the collar.
A very big mahalo to Team Spectrum for sharing their design! We were already headed down the same path, but learning about the Banebots wheels with the VersaPlanetary gearboxes sure got us to our final design a lot quicker.
In our latest round of testing we shot some upside down discs successfully into the middle and high goals from up close using the same wheels speeds as a right-side up disc without a cover. Upside down shooting was more sensitive to feeding though. If it wasn't fed quite right the disc would pop up from the first wheel. We'll probably add a cover to take care of this issue.
