The Lothar Fechter Defiant is a 4 seat amateur-built push-pull, twin
engine canard. Two Lycoming O-360 series tractor-pusher engines drives an pull
and a push prop. The Defiant is designed by Burt Rutan. In 1974, Burt
Rutan started Rutan Aircraft Factory (RAF) in Mojave, California, in
order to develop his design of a non-conventional research aircraft. The
prototype of this research aircraft, Rutan Model 40 Defiant s/n 001 N78RA, flew first on 30 June 1978.
The Defiant was intended as a proof-of-concept of a very safe light twin
design, requiring little trim change and no pilot action in case of
engine failure, and with good single engine performance. In 1979, the Rutan Aircraft Factory announced they would proceed with
certification of a Model 40 Defiant based light twin. Adequate financing was not
secured for this project, and the design was modified for homebuilt
construction as the Model 74. Work began on production Defiant Model 74 in 1982. Plans were offered in mid-1984.
One of the homebuilt Defiant Model 74 was built by Lothar Fechter at Flugplatz Leer-Papenburg in Germany.
