TerryLeave a comment

An 80% scaled replica version of the Waco ATO. Construction began in May 1983.
The four wing panels are identical but required 48 ribs built during 1983. Each panel contains 12 truss type spruce ribs, and the 6 foot centre section has nine constant chord ribs. The wings retain the original M-6 profile. The chord of the centre section ribs is 4 ft 1.5 in, and outboard ribs 2 ft 10.5 in. The spars are solid planks, the forward being 5 x 11/8 in and the rear spar 4 x 1 inch. The four ailerons each have six ribs and are equal span and chord. The wings are braced with dual straight 4130 steel outboard struts and N centre section struts, and streamlined stainless steel wires. The fuselage and tail components are welded 4130 with wood formers and stringers in the fuselage and wood fairings at the fin and stabiliser roots.
The tail spans 8 ft 10 in and rudder stands 3 ft 3 in. Rudder and aileron are cable controlled and the elevator through torque tubes. The main undercarriage is a welded outrigger type with Cleveland brakes, and a 5 ft 2 in tread. A Scott 3200 tailwheel holds an 8 inch tyre.
The first flight was in August 1987. Total cost: approx US$15,000.

During 1911-1914, several single and two place open cockpit biplanes were built apparently following the Curtiss design as exhibition ships. Later models with fabric-covered fuselage and rounded wingtips made them quite modern for their day.

The 1911 original had a 60hp Hall-Scott motor and later versions 80hp Curtiss power.

Williams soloed his own creation at Hyde Park Aviation Field (Pasadena CA) on 26 August 1911 at age 19 as the world’s youngest licensed pilot, according to Aero Club of America officials.

Williams Aircraft Design W-17 Stinger

The Williams W-17 Stinger is an American homebuilt racing aircraft that was designed for Formula One Air Racing by Art Williams and produced by his company, Williams Aircraft Design of Northridge, California, introduced in 1971. The aircraft was at one time available in the form of plans for amateur construction, but only one was ever constructed.

The W-17 Stinger features a cantilever mid-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration.

The aircraft fuselage is made from sheet aluminum in a monocoque structure. The wings are all-wood, with laminated spruce spars. Its 19.0 ft (5.8 m) span wing employs a NACA 64008 airfoil at the wing root, transitioning to a NACA 64010 at the wing tip. As the Formula One rules require, the engine is a 100 hp (75 kW) Continental O-200A powerplant.

The W-17 has an empty weight of 585 lb (265 kg) and a gross weight of 835 lb (379 kg), giving a useful load of 250 lb (110 kg). With full fuel of 8 U.S. gallons (30 L; 6.7 imp gal) the payload is 202 lb (92 kg).

Only one example of the W-17 Stinger was registered in the United States with the Federal Aviation Administration in 1971 (N21X). The sole example was raced at the Reno Air Races by pilot John P. Jones in 1973 and captured second place. It went on display at the Planes of Fame Air Museum.
