Catalogue of Drive Gearings

Due to frequent questions and discussions on drive speeds, but not a lot of resources on the layouts of the possible gearings themselves, I’ve created this resource for people to see a catalogue of drive speeds that I’ve deemed as viable, and some commentary on each layout. All drives shown here are on 6 motors, and all drives here are compatible with center traction wheel. (some drives have 8 wheels so traction will be offset from center). The layouts shown can easily be translated to 4 motor …

600 rpm direct (36:36) is pretty much the only one you can do.

Hailstorm last year had a good drivetrain:
