I'm actually working on two designs right now - one for an offseason project that will actually be built and another that is just for practice.
The Real One -
6WD with 8" pneumatic wheels
4 cim motors with a 6.67:1 reduction on a custom gearbox, center wheel direct driven off the gearbox with the other two wheels being powered by belts (using the 42 tooth AM pulleys)
(I know it's going to be ridiculously fast but it's for a t-shirt cannon that needs to be able to cross a football field in a reasonable amount of time)

The Practice One -
6WD with 4" plaction wheels
6 cim motors with a 6:1 reduction using a VEXPro single stage gearbox
external reduction of 1.08:1 (AM 39 tooth to AM 42 tooth)
