I have some preliminary information on the cs planetary psru I am helping develop. Reduction ratio presently 2.92! Great reduction ration for rx8s.
It looks like the actual position of the propeller governor from the propeller shaft centerline to the top of the governor is 290 millimeters (11.5 inches) and the angle is 35 degrees from the vertical position. The reducer length from the propeller shaft flange to the engine would be about 400 millimeters (15.75 inches) and the weight of the reducer will be about 32 kilograms (70.5 lbs).

Please ask questions so I can figure out the most flexible package.

Does anyone know the Marcotte weight or the Mechanir weight of their cs psru's? I know Tracy's non cs is about 45 lbs.
