Thanks for your new products. I'm especially excited about the traction wheels. A couple of questions...

1. How might one convert your traction wheel to accommodate a 1/2" keyed shaft?

2. The wheels seem to be wider than one would think necessary. Is that for strength, or to keep the tread on?

3. What are the advantages of your single speed transmission over the kit transmission?
1. A hub would need to be made, with these features:
  • 1/2" hole & 1/8" keyway
  • OD of 2.375" (or greater)
  • 6 evenly spaced #10 clearance holes (.21), at 60 degrees from each other, on a 1.875" diameter bolt circle
We may provide this hub in the future, but we currently don't have it as a listed product.

2. Wheel widths vary as drivetrain designs vary. In FIRST, there are wide ranges of wheel designs. Some use wide wheels for more floor contact, while others use narrow wheels. This also depends on how teams wish to play the game. These Traction Wheels are a compromise between wide and narrow wheels. Also, they can easily be narrowed if a designer chooses.

3. The differences between the AM Gearbox and the Kit Transmission are as such:
  • to buy either, the AM Gearbox is less expensive
  • the AM Gearbox body is smaller than the Kit Transmission
  • the output shaft of the AM Gearbox is 1/2" while the Kit Transmission is 16mm
  • the Kit Transmission has the ability to be elegantly coupled with another Kit Transmission to create an increased reduction (for arm applications), while to do this with 2 AM Gearboxes requires some more design work
  • the AM Gearbox is lighter and includes gears with narrower face widths

Thank you for the interest, Charlie.
