A few gearbox questions

[colt527]

Ok, first here is our gearbox setup. We combine the CIM's and the drill motors together in a very simple design where we matched the RPM's using gears and chains. More specifically we are using the drill motors inside their normal transmission supplied by the KOP, in low speed, with the backdrive-pins taken out and on the 15 clutch setting. Here are the questions:

1.) Are we really getting the full benefits of combining the 2 motors into one side because we are using the drill motor transmission supplied by the KOP. To me, it just doesnt make sence. As soon as the drill motor's transmission's clutch starts to click, the drill motors are not supplying any force any torque and its just like running the CIMs by themselves.

2.) Is it really hazardous to the drill motors to put the transmission in direct drive. We have burnt many a drill motor before but if the CIMs are helping it out, should this really be a concern?

3.) We are currently running all the motors through 30amp breakers because we did not have another 40 fuse box lying around. Could this cause problems?

4.) Is it possible to burn out the CIMs, if stall amperage is 50amp and its running through 30amp fuses.
