This is stunning in it's simplicity.
since I am using the proven Ford A4OD six pinion planetary in a differential
mode the total gear reduction is 6.34:1. The ring gear is rotating
in one direction and the planet carrier is rotating in the other.
As long as both props have the same drag the RPM's of each prop
will be equal. With an engine RPM of 8500 the rotors will
be turning 1340 RPM. We can probably use a 13 to 14 foot diameter
rotor at this RPM. The red line on the RX8 engine is 9000
RPM and a P-port RX8 engine will be making close to 300 HP
or more at 8500 RPM. We will find out in a few weeks
as I am building such an engine as we speak

The over all diameter of this gear box is only
about 6.5 to 7 inches. It will have it's own oil
supply as it is on the very front of the airplane and
the engine is at the very rear for weight and balance reasons.
There is an stock RX8 carbon fiber drive shaft connecting the two.

The first 3D is with gear box housing.
The second is without gear box housing.
The third is with the aft prop shaft.
The gimbal is centered on the U joint which is a requirement.
The gimbal allows the props to be pointed in any direction with in
limits. The same as the Air Scooter. This will allow maneuvering in landing
and take off mode and help with the transition to horizontal
flight and back to vertical flight.

Did we luck out or what?
