How to gear a 4 motor drivetrain with 6 wheels

If anyone can help me, that would be great.
Since Over Under came out, i was thinking of using a 4 motor drivetrain with 6 wheels, but I don’t know how to do so and if anyone could help me, that would be very helpful for me. If you can send pictures that would be awesome.

The best resource I can give you is this:

If you are a first year team then I would recommend a slower gearing, no faster than 60 in/sec. Hope you find what you’re looking for! If you have any other questions, feel free to ask!
