Ken,
They are of an original design and have
been in use in helicopters in Eastern
Europe for some time. It is
not, I believe, based on any car/truck planetary design-the reduction unit was
designed originally for aircraft use. I will check with the factory, however.
Thanks for asking. BTW, it is a 2.92 reduction, not 2.95.

development
What are the 2.95 planetary's from ??
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.
