• One main rotor.
• The hub will be Teetering Rotor with 3+ Blades and Offset Hinges or Teetering Rotor with 3+ Blades, Constant Velocity Joint and Hub Springs
• Two pusher prop/rotors
• The prop/rotors face down to assists the single rotor during hover.
• The prop/rotors face back during forward flight.
• Each prop rotor has a diameter approximately 1/3 of that of the main rotor.
• The prop/rotors have 3 or 4 blades. These additional blades will keep the prop/rotors relatively small.
• The two prop/rotors have the same direction of rotation and they counter the main rotor's torque hover.
• The prop/rotors have constant speed control and they have a fixed relationship with the main rotor, therefore the main rotor has a constant speed as well.
• The hubs of the prop/rotors are behind the pilot during cruise and below the pilot's seat during hover.
• There is one central gearbox.
• A single pinion drives two crown gears. From the crown gears the power goes out to 4:1 ration crown and pinion gearboxs at the hub of the prop/rotors. This arraignment should eliminate torque that would cause a problem when rotating the prop/rotors between rotor and prop. I superficially think.
• The gearbox also includes the crown and pinion gear that sends power to the main rotor.
• The fuselage, supports and tail boom might bolt to this gearbox.
• See Gyro/Heli II for somewhat related information. Its drawing could be modified for a one-seat craft. Consider tandem seating for two-seat craft
