Büttner Crazy Plane Explained
The
Büttner Crazy Plane is a family of German
paramotors designed by Gerald Büttner and produced by
Büttner Propeller of
Obernkirchen for
powered paragliding. The aircraft are supplied complete and ready-to-fly.
[1] Design and development
The Crazy Plane line was designed to comply with the US FAR 103 Ultralight Vehicles rules as well as European regulations. It features a paraglider-style wing, single-place or two-place-in-tandem accommodation and a single engine in pusher configuration with a reduction drive and a 115to diameter Büttner Propeller designed propeller.[1]
As is the case with all paramotors, take-off and landing is accomplished by foot. Inflight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw.[1]
