Re: pic: 3 CIM WCD Crazy Geabox
 

It's a neat idea, if (as you noted), pushing too far unless you REALLY need that low profile. If it's that important, perhaps you could put one (or maybe even two) of the CIMs on the wheel side of the gear planes, either ahead or behind the wheel. It would limit the wheel size, but it sounds like you've already committed to that anyway. Oh, yeah, you'd have to wire or control the wheel-side CIM backwards.
