I would look at the MT 643 or the newer MD3060 transmissions for the
 first gear planetary. The Allison 1000 is the transmission used in GM
 3/4and 1 ton trucks..Lots of parts and the price may be good but the
 MT643 or MD3060 will give 3.5:1 ratio. That would allow 10,000RPM and
 close to 3,000RPM at the prop. Get full use out of building a
 different PERU.

Are you sure about that ratio. Can you get the dimensions of the ring and
sun gears?

I have decided to build our own planet carrier out of 7075T6 and add two
pinions. Six total up from four. 50% more torque capabilities.

Thje parts are cheap.

Paul,   Would be great if you could get a serious racer with your air-frame of
choice  and interested in the Turbo 20B on board for the project........

.Do you think the Reno establishment would change the rules to sandbag the Rotary
if the piston guys felt threatened ??........(Like the road racers did)............<:)
