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.[1][2][3][4]

Fisher Flying Products was originally based in Edgeley, North Dakota, USA but the company is now located in Vaughan, Ontario, Canada.[2][3][5][6]

Development

The Avenger was designed to meet the requirements of the United States FAR 103 Ultralight Vehicles, including the maximum 254 lb (115 kg) empty weight. Design goals included low-cost, an aesthetically attractive look and accommodation for a 76 in (193 cm) tall, 240 lb (109 kg) pilot.[3]

Although originally designed to accept the 1/2 VW powerplant the aircraft can achieve an empty weight as low as 250 lb (113 kg) with the use of a lighter weight engine, such as the 28 hp (21 kW) Rotax 277 or the 35 hp (26 kW) 2SI 460-35. The Avenger was initially marketed with the now-discontinued Rotax 277 engine, but the use of this engine has been criticized as leaving the aircraft underpowered.[3][5]

Reviewer Andre Cliche says:

“ The Avenger is an experimental-class design that has been re-engined to fall under the ultralight regulations. For this purpose, a 28 hp Rotax 277 has been installed, thus allowing the weight to get lower than the 254 lbs. upper limit imposed on ultralights. This is technically feasible but the switch from a VW engine to a single cylinder Rotax also reduces the performance below a safe level. The rated 400 fpm rate of climb is barely adequate for safe operations. Put this machine in the wrong situation and it can bite you.[3] ”

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.[2][3]

The cockpit features an optional removable canopy.[5]

The Avenger has an estimated construction time of 400 hours from the kit.[3][7]

In 2011 the kit price (without paint, varnish, pilot/passenger restraints, instruments, upholstery, engine, engine mount or propeller) was US$5999, with the plans selling for US$300.[6][8]

Recommended engines include the 50 hp (37 kW) Rotax 503, 40 hp (30 kW) Rotax 447, 35 hp (26 kW) 2SI 460-35 or 38 hp (28 kW) 1/2 VW.[5]

Operational history

In December 2004 the company reported that 50 Avengers were flying, the majority as US unregistered ultralights.[4]
