If you understand the concept of "Power" you will understand immediately the various benefits multiple motors will provide you. Research this concept (check out a physics textbook, talk to a physics teacher, talk to a mechanical engineer, etc) and you'll be all set. This is one of those FUNDAMENTAL concepts for drivetrain design.

Honestly,
I'm floored by the number of people who design FIRST drivetrains with seemingly no knowledge of this concept.

John, thanks for the info. Didnt really consider the current draw and its effects.
I can attest that you will definitely get more power using 2 instead of 1 motor per tranny. But specifically for our situation, we were forced to use a 1 CIM, 1 FP with planetary gearbox setup since we needed the CIM for other functions and due to weight issues. We gave up on the idea at championships because with 2 CIMs per tranny, the response and power was noticeably greater especially around the turns of the field. I can only imagine what it would have been like if we only had just 1 motor per tranny to do this.
