old Kalt autogyro
would that be the 'Robin' autogyro that pre-rotates by a drive from the right hand u/c wheel ??
If it is then I have yet to see one fly successfuly ! I know of one in Scotland that got airborne for about 2 seconds . Apparently its a nightmare to steer on the ground during pre-rotation and if you disconnect it the thing never spins up to full autorotation.
I would love to see you be successful with it though !
Best of luck
