On the motor side, it's drilled to accept the motor output shaft. we than have a setscrew. It adds about .5 to the overall length of the system, but no mods to the gear were required.

We ended up doing something similar. A mentor from 245 (I think?) suggested that we put a keyway in the aluminum backing plate of the motor with a file (thanks for the vice 1388!). It wasn't a solid fix, but it survived through the eliminations and all through championships.
