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.
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.
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.
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.||”|
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 features an optional removable canopy.
In December 2004 the company reported that 50 Avengers were flying, the majority as US unregistered ultralights.
