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, United States, but relocated to Vaughan, Ontario, Canada. [2] [3] [5] [6] [7]
The Avenger was designed to meet the requirements of the United States FAR 103 Ultralight Vehicles regulations, including the maximum 254 lb (115 kg) empty weight. Design goals included low cost, an attractive appearance, and accommodation for a 76 in (193 cm) tall, 240 lb (109 kg) pilot. [3]
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 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, [5] which was criticized as leaving the aircraft dangerously underpowered. [3]
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]
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 has a removable canopy. [5]
The Avenger has an estimated construction time of 400 hours from the kit. [3] [8]
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. [6] [7] [9]
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] [7]
In December 2004, the company reported that 50 Avengers were flying, the majority as US unregistered ultralights. [4]
