Pobjoy Airmotors Ltd

UK
Founded 1930 as Pobjoy Airmotors Ltd., engine manufacturer. In 1935 became public company and enlarged scope to include aircraft manufacture. Chairman Oswald Short, managing director Arthur Gouge. Built Pirate high-wing monoplane 1935, but performance disappointing. Acquired license to build Short Scion and Scion Senior light transports. Short Bros took over all Pobjoy’s issued shares in 1938. Company was subcontractor for aircraft parts in Second World War.

Poberezny Little Audrey

Little Audrey, built by Paul Poberezny, was derived from Benny Howard’s Pete racer, after rebuild as the Baker Pete / Special.

It was bought by EAA in 1953, and redesigned as Pober Little Audrey with a replica fuselage and Luscombe shoulder-wings. The original fuselage and tail, plus some miscellaneous parts, went into a rebuild of the 1930 configuration by Repeat Aircraft, Riverside CA.

Pober P-9 Pixie / Acro Sport Inc Pober Pixie

The single-seat Pober Pixie is another homebuilt designed by Paul Poberezny. It originally started as an effort to help pilots beat high operational costs and was designated Project Econoplane in 1974. Inspired by a Heath Parasol LN, the Pixie is a parasol monoplane powered by a Limbach VW engine rated at 50 to 75 hp. Full-span ailerons give excellent roll with little yaw on entry and recovery. This is a beginner’s project for construction, with highly detailed plans, and the cost level is low. Can be powered with a VW conversion or Continental A-65.

The fuselage is 4130 steel tube, wings are Sitka spruce, covering is with Stits Poly-fiber.

P.M. & T. Honeybird

Single seat single engined high wing monoplane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; conventional tail. Pitch control by elevator on tail; yaw control by fin mounted rudder; roll control by quarter-span spoilerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile NACA 23015; 100% double surface. Undercarriage has three wheels in tail dragger formation; suspension on tailwheel and axle flex/ rubber suspension on main wheels. Push right go right tailwheel steering connected to yaw control. Aluminium tube framework, with pod. Engine mounted below wing driving pusher propeller.

Pod made from Keviar/Carbon fibre. Composite construction wing uses aluminium tubing to British HT30TF specification, Styrofoam, and wood veneer covering.

The Honeybird is a sophisticated pod: it is non structural and is attached to an aluminium framework.

Although the Honeybird is a microlight by definition, it is being built under the aegis of the British homebuilders association, the PFA, whose engineering requirements insist on gravity rather than pumped fuel feed. The main fuel tank is therefore in the wing, with a reserve situated aft of the pilot.

The Honeybird is basically a homebuilt, which in 1982 had yet to make its first flight.
