Introduction1975
Developed from Piper J-3

The Wag-Aero CUBy is a replica of the Piper J-3, designed by Dick Wagner and marketed by Wag-Aero of Lyons, Wisconsin as plans or in kit form. [2] [3] [4]

Contents

The aircraft is currently marketed under the name Wag-Aero Sport Trainer. [5]

Design and development

Wag-Aero started with a line of inspection covers, then eventually a comprehensive line of aircraft parts, including a full line of parts for the Piper Cub. After several attempts to purchase the rights to the Piper Cub for new production, Wag-Aero owner Jack Wagner designed a homebuilt kit that would allow homebuilders to construct new aircraft similar to the Cub. [6]

While the CUBy was initially offered with wooden wing ribs and spars like the Piper Cub, aluminum ribs and spars were later added as an option, also like later Cubs. The aircraft does differ from the original Piper design in several ways including having its fuselage fabricated from 4130 steel instead of the Cub's original 1025 carbon steel and utilizing a conventional elevator-mounted trim tab in place of the Cub's jack screw trimming system that adjusts the Cub's elevator angle of incidence. [2] [6]

The CUBy drawings were drafted by Bill Blake. [7]

The prototype first flew on March 12, 1975 fitted with skis. [8]

Operational history

The introductory model was displayed with a contrasting paint scheme, one half painted green with a yellow stripe, and the other half painted yellow with a green stripe. This unusual "court jester" paint scheme was used to differentiate the prototype from the standard yellow scheme used on the Piper Cub, for marketing purposes. [9] Paul Poberezny became the first customer to build a CUBy. [6] Poberezny's aircraft became part of the EAA AirVenture Museum Foundation [10] and was used to demonstrate the use of automotive fuel in aircraft engines for the Experimental Aircraft Association. [11] The designer of the aircraft Dick Wagner flew the unpressurized aircraft as high as 20,000 ft (6,096 m) to demonstrate that auto fuel would not cause vapor lock. [12]

The Piper PA-8 Skycycle was a 1940s American single-seat light aircraft designed and built by Piper Aircraft at their Lock Haven, Pennsylvania plant. Towards the end of 1944 Piper announced a number of aircraft it intended to build after the second world war. One of these was the PWA-8, an aerodynamic test aircraft was built with the name Cub Cycle and it first flew on 27 August 1944 with a small two–cylinder Franklin Engine. The Franklin engine was replaced by a four–cylinder Continental A-40-3 of 37 hp (28 kW); the aircraft first flew with the Continental engine on 12 September 1944. The Skycycle was a fabric-covered mid-wing single-engined single-seat monoplane with a tailwheel landing gear. The fuselage was produced using an auxiliary belly fuel tank as used on the F4U Corsair. The Cub Cycle was scrapped and a similar but new aircraft was built with the name Skycycle, which first flew on 29 January 1945 using the same Continental engine as the Cub Cycle. The aircraft was further modified in 1945 with a four-cylinder 55 hp (41 kW) Lycoming O-145-A2 engine and designated the PA-8 Skycycle. No further examples were built.
