Our friends at www.flugwerk.de/ ,who are rightly famous for having built several Fw 190 A8 full size flying replicas have, in the last year built a FW190 D9N (for "New") . They used a modified Allison engine . Thats Gunther Rall who must be in his late 80's,having just autographed it . Other than the FW 190 D13 in Seattle at the Museum of Flight, this FW 190 D9N is the only other flyable D model . Congrats to Flugwerk !
