- Find a better way to mount the motors and planetary combos. I think the current method isn't going to cut it. I think in the NBD setup, there is a plate between the CIM and DW tranny. I would modify this plate to look something like the ones in the KOP and mount the CIMS that way.
-How thick are the gearbox plates? I'd say anything over 1/4" is overkill.

-The gears are off the "shelf" from firstcadlibrary.com and probaley will purchase smaller for the actual assembly.
-I thought of moving the gears closer to each other to save space (one and 3 o'clock and one at 7 o'clock) but decided against it sice it might put too much troq unevenly spread over the center gear, and flexing the shaft.
-The NBD setup does have a plate between the moter and the tranny but i didnt make the actual dewalt trans i just used was a bosch i could find for the representation.
-The plates are 1/4.

We plan on using one servo to shift the dewalts. Just to mount the servo in the middle and use heavy gage wire (just to clairify not the kind you electronics box uses.) to attach to the shifters.

Thanks for all the input

Email me if you want any more pics since they are too big to attach
