Re: Poll: How many CIMs are you using?

You wouldn't need reduction on a CIM or MiniCIM? Relatively few mechanisms work well without any gearing at all.

A VP stage and ring gear (not including ends) is 0.132 lbs, well under the weight difference if you just need an additional 4:1 stage in an existing gearbox. You could also use a CIMile for the 775Pro (but not BAG motor) which weighs 0.4 lbs, still under the weight delta of switching to a CIM.

There are also many suppliers of 32dp gears or small pitch belts which can be mounted directly on a 775Pro shaft. There are plenty of ways to use these great motors.
