If you are intent on a 3 motor per side drive, you may consider the type of arrangement shown in
this picture. All it would require is a .8 module gear that is approximately 1/4 the number of teeth of the 50T gear that is on the CIM (12 or so teeth should do nicely). Press it on the FP motor and then figure a mounting method to allow the motor to mate with the 50T.
If FIRST would have given Banebots more time, I think they would have built the mounting system right into the mold for the plastic housing. In fact, given just a little more time, I may have gotten my request to have the pitch of the gears for the adapter changed to 32 DP to match the gear that the FP comes with (32 DP = .79375 module which is very close to but not exactly .8 module).
If we had done this (and changed the housing tool to accept FP motors and had we know how many teeth were on the FP motor), we could have made gearbox that could take up to
4 motors (2 CIMs and 2 FPs) without requiring any motor changes. Now THAT would have been cool.
Ah well... ...perhaps some other year.
