Re: Gearing and Drive Motors
We're using a pair of VexPro 3-CIM Ball Shifters on our drive with 2 CIMs + 1 MiniCIM on each gearbox.

The gearboxs use the 3.68x spread options between the high and low gears and also has a 3rd stage reduction giving us an overall ratio of 7.08:1 (10.85ft/s with 4in wheels) in high gear, and 26.04:1 (2.95ft/s) in low gear.

Re: Gearing and Drive Motors
My team is using a custom single stage gear box. Styled after the WCP Single speed gearbox. Set to a top speed of 12.6ft/sec we will be a speed demon. With multiple options for additional gearing changes to match the meta. A unique feature about our gearbox is that they only have one plate per side, the other plate is essentially built into the drivetrain.
