Fisher Avenger
Introduction The '''Avenger''' is a single-seat, Canadian low-wing, tractor configuration ultralight aircraft. The Avenger was introduced in 1994 and is available as a kit or as plans from Fisher Flying Products.Fisher Flying Products was originally based in Edgeley, North Dakota, United States, but relocated to Vaughan, Ontario, Canada.
Development The Avenger was designed to meet the requirements of the United States FAR 103 ''Ultralight Vehicles'' regulations, including the maximum  empty weight. Design goals included low cost, an attractive appearance, and accommodation for a  tall,  pilot.Although originally designed to accept the Half VW powerplant (a Type 1 Volkswagen  engine block cut in half), the aircraft empty weight can be reduced to  with the use of a lighter weight engine, such as the  Rotax 277 or the  2SI 460-35.The Avenger was initially marketed with the now-discontinued Rotax 277 engine, which was criticized as leaving the aircraft dangerously underpowered.Reviewer Andre Cliche says:
Design The Avenger structure is entirely constructed from wood, with a low wing braced to the landing gear. The wooden-framed wing is covered with aircraft fabric. The engine cowling is fibreglass. The conventional landing gear features a steerable tailwheel and main-gear suspension.The cockpit has a removable canopy.The Avenger has an estimated construction time of 400 hours from the kit.In 2022 the kit price (without paint, varnish, pilot/passenger restraints, instruments, upholstery, or engine) was US$9320, with the plans selling for US$350.Recommended engines include the  Rotax 503,  Rotax 447,  2SI 460-35 or  1/2 VW.
