In the 1930s, Fleet Aircraft manufactured a series of single-engined, two-seat training aircraft, based on US designs. The Fleet Model 7B and Model 7C, known respectively as Fawn I and Fawn II were purchased by the RCAF as primary trainers. After years of reliable service, many were available for use in the British Commonwealth Air Training Plan during the Second World War while others remained as station "hacks."

[edit] Design and development
As a subsidiary of Consolidated Aircraft set up in 1928, Fleet Aircraft had factories at Buffalo, NY, and across the border at Fort Erie, Ontario. The Canadian company produced a series of single-engined, two-seat training aircraft, based on US designs but including variants adapted specifically to Royal Canadian Air Force (RCAF) needs.
The Fleet Model 7 began as an American design, the Model 2, originally designed by Consolidated. Besides two prototypes imported from the US, a total of seven Fleet Model 2 trainers were built in Canada for civilian operators.
Derived from earlier Fleet Model 2, the Model 7 featured an aircraft structure consisting of a fabric-covered, welded-steel fuselage with metal panels forward of the wooden cockpits. It had steel-tube faring formers and wooden stringers. The wings were single bay of equal spans and wire braced. The upper wing was made in one piece and constructed with two solid Spruce spars. Ailerons were found only on the bottom wings. Stamped aluminium alloy ribs were used to construct the wings and steel-tube compression struts were at the interplane and centre section of the wings. Interlaced between the wings were streamlined landing and flying wires. Except for an enlarged tail-fin introduced after the first production series, the Model 7 was superficially identical to its earlier predecessor.
A variety of equipment could be fitted to the Canadian variant including optional wheel brakes, a tail skid or tail wheel arrangement, a fuselage belly tank and a fixed cockpit enclosure or "coupe top" with hinged sides. During the late 1930s, a sliding cockpit enclosure became standard equipment of all RCAF Fawns. The aircraft could also be configured to use skis, floats or wheels. The main landing gear's "radius rods" (the members that joined the inner ends of the wheel axles to the fuselage) on the Models 2 and 7 were notable for having the one coming from the left wheel "looped", with an open oval piece near its middle, so that the one from the right mainwheel could pass right through it.
Engine choices further dictated the different variants of the Fawn design: the Mk I (Fleet Model 7B) with a 125 hp Kinner B-5 engine was superseded by the Mk II (Fleet Model 7C) powered by a 140 hp Armstrong Siddeley Civet seven-cylinder radial engine. Although the RCAF ordered the bulk of the production runs, 12 civil-registered Model 7Bs were completed for the Department of National Defence to be issued to flying clubs.
[edit] Operational service
The Fleet Model7 first saw service with the Royal Canadian Air Force in 1931 when 20 Mk Is were delivered. As a two-seater primary trainer they were felt to have excellent flying characteristics together with a rugged strength which inspired confidence in novice pilots. The RCAF was very impressed with the Fleet Fawn and claimed that the aircraft was one of the factors which improved its flying standards during the 1930s.
A total of 31 Model 7Cs were built between 1931 and 1938 at the Fleet Aircraft of Canada's plant at Fort Erie, Ontario, with the first deliveries made in 1936. Due to the smoother, quieter and more powerful engine, the Model 7C was considered the definitive variant.
Forty three Fleet Model 7B and C trainers were operational with the Royal Canadian Air Force when war was declared in 1939. In service during the Second World War, the RCAF adopted the name "Fawn" for both variants. Along with the more modern follow-up design, the Fleet Finch, Fleet Fawns helped train thousands of pilots under the British Commonwealth Air Training Plan during the war. The Fawn remained in service with the RCAF until 1947.
[edit] Variants
- Model 7A: One example completed with a 100 hp Kinner K-5 radial engine
- Fleet Model 7B (Fawn Mk I): 32 examples with a 125 hp Kinner B-5 engine five-cylinder, radial engine (earliest series also had a 80 hp five cylinder Armstrong Siddeley Genet radial engine and a "left-hand" prop)
- Fleet Model 7C (Fawn Mk II): 31 examples with a 140 hp Armstrong Siddeley Civet seven-cylinder, radial engine
- Model 7G: A "one-off" conversion of a Model B with a 120 hp de Havilland Gipsy III, four-cylinder, inline engine (converted back to Model 7B standard)
