Hi Paul

I expect there are a few folks on here who have actually owned and flown the thing successfully so never fear !

Maybe you remember the 'Hobbit' autogyro ? Same kind of setup but pre-rotated by a pulley fixed to the mast which you wound a length of chord around and when you powered away you trapped the other end of the chord under your foot, thereby rapidly spinning up the rotor as it unwound.......might work ?

had a gander at your site, maybe you could strap a turbine to each rotor tip
