Competition Aircraft Firebird Flyer

Single seat single engined high wing monoplane with hybrid control. Wing has unswept leading and trailing edges, and constant chord; inverted V tail. Pitch/yaw control by elevon; roll control by full span ailerons; control inputs through stick for pitch/yaw/ roll. Wing braced from below by struts; wing profile; double surface. Undercarriage has three wheels in tricycle formation; suspension on all wheels. Nosewheel steering independent from yaw control. No brakes. Aluminium tube framework, without pod. Engine mounted below wing driving pusher propeller.
In 1983 this machine was still in its prototype stage and therefore its characteristics and performances are not fully known. However, R J Davies has two original ideas in this new design. Firstly, the full span ailerons can be operated together to serve as flaps. Secondly, the motor on the Firebird Flyer (a Spitfire 250FA of 28hp or possibly later a water-cooled 220LC of 35 hp) drives a two bladed pusher propeller, which rotates about the axis of the tubular metal boom which carries the tail.

Comper CLA.7 Swift

The company’s first product was the C.L.A. 7 Swift, a single-seat high-wing sporting aircraft, which was first flown in spring 1930 and built between 1930 and 1934 (one was owned by the Prince of Wales, later Edward VIII).

Teething problems necessitated fitting early production Swifts with the Salmson A.D.9 radial, the prototype having flown with a 40 hp ABC Scorpion.

Production commenced in 1930, thirty-seven Swifts being built. The majority powered by the 75 hp Pobjoy R, but three were fitted with 120 hp DH Gipsy III.
