This autogyro was built by Dr. Keita Sakon from plans of Richard Anderson who lives in Indiana. The plane is powered by a Norvel AME .061 with a 33 inch rotor. It has a weight of approximately 16 ounces when dry and has a disc loading of 2.69 oz./sq. foot.

It's controlled by a throttle and two servos that tilt the rotor sideways and back/forward, which is similar to cyclic control in a helicopter. This is generally called the DC (direct control) by gyro people, as opposed to a fixed rotor system with controls on elevator/rudder found on an airplane. However, pitch of the blades stays constant, unlike a helicopter that usually has a symmetric airfoil.

This plane has a flat bottom Clark Y airfoil that was made out of Sig airfoil shaped balsa. The vertical and horizontal "hang angles" is a critical adjustment, which is like adjusting the CG on an fixed wing. When this picture was taken, the blades were whirling around at a terrific speed. Watch those fingers Doc.
