Hey Paul,

I am working out a water jacket for my OMC 45hp rotary, and
contemplating putting the e shaft in the lathe can putting a oil
channel to help cool the shaft. I am modifying the heck out of this
one to test if it can take oil cooling.

It has a regular intake port and then a mid to high speed intake port
that does not go thru the case like the charge cooling does.

I am working on a way to recover the oil from the shaft without
filling the case.

I need to figure out how to use a small Ford C6 planetary unit to
gear it down. I am planning on using it for a small single seat
helicopter, the weight is perfect and the HP will work. Just need to
cool it really good and reduce the rpm. I want to use the C6 unit
along with my sprag clutch.

Any suggestions?

Thanks David Mikesell

My guess is th biggest problem will be the oil sealing on the
sides of the rotors. Probably what will happen is a LOT oil smoke
on start up and much less when it it running for awhile.

The C6 is the same as the recent planets but there are six
pinions rather than only 3. There is not much difference in weight.

Use the rear planet and lock the ring gear.
Take power out of the planet.
