Unless you're also changing the gearing (aside of just balancing out the free speeds of the FP and the CIM), how are 2 FP motors going to be twice as fast as a single CIM? CIM motors are roughly 250W motors (@10.5V), while FPs are 140W (@10.5V). Even with 2 FPs, you're only slightly passing the power a single CIM provides, and certainly not doubling it. Even if you're looking at the power @40A, you're still not doubling the power of the CIM motors.

Amen sean. I was wondering the same thing. the easy calculation is the fp = 1/2 of a cim. Definitely not 1 cim =1fp.

Still though tthere lifter is possibly my favorite. I know its not the fastest but its so simple in my eyes. Good luck 343 you guys are awesome.
