Re: Can Victor and Jaguar motors work together on a single gearbox?

There's no "torque fight" until you reach the free speed of the motor with the lower free speed (the CIM in this case). Above that speed, the CIM acts as a generator (causing negative torque). However, you'll likely not reach that speed in a typical FRC application (e.g. drivetrain).

You can't adjust the motor's power without knowing the motor's speed. But if you want to assume a given operating speed, you can adjust the motor commands to match power or current.
