Wish I knew Wayne.....I think it is an outstandingly good looking machine.Hi Ed,
What model of 4 seat gyroplane is that? The rotor head resembles an early Hughes 500 rotor head & blades. The blades definitely look like helicopter blades with the nominal 8 degree "washout" at the tips, compared to the McCulloch J2 rotor blades with the "washin" tips.
I understood that it is a Russian design.
