A tractor monoplane built by C. G. Spencer and Sons and displayed at the 1910 Aero Show at Olympia. It was designed by Herbert Spencer and W. Stirling, powered by a four-cylinder 40 hp British Aeroplane Syndicate R.H. engine, which drove by chains two propellers of 6 ft. 6 ins. diameter mounted on the leading-edges of the wings. A reverse gear was incorporated in one propeller bracket for opposite rotation. The fuselage was of the “A”-frame type. The machine was tested at Brooklands, but it was not successful and it was soon abandoned.
Bill Spencer designed and built a low cost glider aimed at the “lazy day soaring” crowd. It was interesting enough to be reviewed twice in Kitplanes, a magazine
The fuselage weighs only 29 pounds total. It is built of pop-riveted aluminum tubes and a plywood seat.
The Compact 110 is designed for foot launching from a gentle slope into a steady wind. Essentially, the pilot stands in the cockpit, picks it up, and runs down the slope into the wind until the seat picks the pilot up.
USA Produced SA-550 Spectrum-One as modified Cessna Skymaster, with changes including lengthened fuselage and rear-mounted turboprop engine (first flown 1983).
A rugged, deluxe 2-place trainer and cross country Beaver RX550 has a 10.7 m wingspan, Rotax 503 47 hp engine and weighs 150 kgs. Both aircraft feature fibre¬glass pilot fairing and windscreen as standard equipment. In 1993, ASAP began providing parts and service for the existing Beaver RX550, RX28 and RX35 all aircraft manufactured by a company no longer operating. The demand to continue offering the Beaver aircraft as a kit was high and so in 1996 ASAP introduced the new Beaver RX 550 Plus with new wings, new tail, stronger shock system, better performance but still keeping with its famous docile easy flight of the original Beaver. The prototype of the Beaver Plus first flew in 1995.
