Paul, I really enjoy the site and many ideas it generates. I have one
question. What is the reduction ratio of the C-6 gased planetary gearset you
show in your drawings? many thanks, Bill Jepson
PS I was a youngster at Laguna Seca watching some of my earliest racing and I
was facinated by the Chaparral cars of the era. WRJ

That is an easy one. It is 2.17 to one as most people use it. That is holding the
planet carrier fixed, inputing power to the sun gear and taking power out of the
ring gear. Reverse rotation compared to the engine rotation.

If you fix the ring gear to the housing and take power out of the planet carrier
you will get a ratio of about 3.07 to one. Ross makes such a version. 
This is popular with the gyro guys who run the rotary much faster and get
more HP. Probably well over 200 HP on a 13B with side ports.
