Wolf W-11 Boredom Fighter

12/31/2013. Donald S. Wolf of Huntington, New York designed and built a diminutive sporting biplane known as the W-11 Boredom Fighter, styled to represent a single-seat biplane fighter of WW I vintage. Although based on no single aircraft, it was said to be fairly simple to construct, using a minimum of special tools. It was capable of accommodating a pilot up to 6 ft 1 in (1.85 m) tall and weighing up to 200 lb (91 kg), was intended primarily for sport flying and was not fully aerobatic. Powerplant could vary between 50-100 hp, but a 65 hp Continental A65 engine was recommended.

Design of the Boredom Fighter began in July 1976 and construction of the prototype started in August 1977. The first flight was achieved on August 30, 1979. Plans were available to amateur constructors and about thirty have been registered. The pictured aircraft was built by Peter J.D. Gronow, Carmarthen, Wales, UK, in 1986. In 2003 the aircraft was registered to Christopher M. Bunn, Pen-Y-Fai, Wales.
