The Airplane Factory Eindecker

TerryLeave a comment

One aircraft that lends itself admirably to replication by virtue of its design is the Fokker Eindecker. This 1914 design has been reproduced in scale by the Aeroplane Factory, Dayton, Ohio; its original flying and landing wire concept adapting readily to modern microlight construction methods. Powered by a Rotax 277 developing 27 hp, this 36 foot wing span replica has a cruise speed of 45 mph and comes in kit form. Centre mounted joy stick, rudder pedals, tail wheel steerable through rudder pedals.
