The plan is to have the arm motor mounted "up high", so weight is a big concern....less weight up there means less tendency to tip. Adding a remote drive system to it also adds some weight "up high", but not as much as putting a CIM up there.
But that is an interesting idea of combining two different types of motors to drive the arm, thanks!

BTW globe motors back drive pretty easily with seemingly little forces on them

We did an experiment with a Globe using a wrench and a scale....the Globe will back drive with about 1/5 the load we plan to apply to it, so this could be a serious problem.
