Reported in 1964, the Frazer-Walker Gyrojet four-place VTOL amphibian to be built by Handley Page Ltd, London, sold in the US by Frazer-Walker Aircraft Corp, New York, has a 250hp Lycoming engine mounted aft driving a two-bladed pusher propeller. Lift is from a three-blade rotor fitted with mechanical “spin-up” device for short takeoff and a tip-jet powered system for use when a vertical takeoff is desired. The fuselage is of fibreglass. Royor blades are uncoupled from the engine in flight and rotate under aerodynamic forces.
Engine: 250hp Lycoming Useful load: 1070 lb Gross weight: 3000 lb Top speed: 145 mph Range: 750 mi
Designed by Colonello Romeo Frassinetti, who founded the now little-known FIAM – Fabbrica Italiana Aeroplani Milano, which probably built this monoplane.
Built in 2003, the Franklin Woodsy 1 N1219J S/N: 1 is an experimental, one of a kind, all wooden, home-built aircraft. A two-seater powered by a Subaru auto engine, the Woodys is very aero-dynamically balanced and has a slow stall speed. The all wood structure has tapered steel rod landing gear and Freise ailerons. Wingspan is 28 ft and cruise 100 mph. It is equipped with two 12 USgallon wing tanks and 3-blade, ground adjustable prop.
In 2020 the Woodsy 1 was for sale with 317 Hours Total Time, engine and airframe. It was located at Wagoner, Oklahoma, USA, and priced at USD$20,000.
The Franklin 12 series of 12-cylinder air-cooled horizontally opposed aircraft engines produced in the 1940s and 50s, (US military designation O-805 was applied to the 12AC-806, 12ACG-806 and 12ACGSA-806).
The Franklin O-805 was to be used in radio-controlled pilotless drones that were to be guided from an accompanying control plane. Due to project requirement changes and cancellations the engine was not produced.
Apparently the engine had no civil application and only a limited military use, as the O-805 in Interstate XBQ-5/XTD2R.
The Franklin O-335 (Company designations variations on 6A4) was a series of air-cooled aircraft engines of flat-six configuration.
These engines were commonly vertically mounted and used to power many early helicopters in the United States. They were closely related to the 2A4 and 4A4 2- and 4-cylinder engines. In various subtypes, the 6A4 remained in continuous production from 1945 to the time Franklin’s United States operations ceased in 1975, with versions continuing in Polish production into the 1990s. 6AC ATC 222, 225
In 1947 this engine was modified into a water-cooled version by the Tucker Car Corporation for use in the 1948 Tucker Sedan. Tucker liked the engine so much that he purchased the Aircooled Motors/Franklin Engine Company and it remained under the ownership of the Tucker family until 1961.
