Design and development

The GW-1 was built in concert with the Tweed GT-1 as both builders shared ideas and tools. The two aircraft share some common design features, although their wings are completely different. The GW-1 first flew in 1959 and at that time had a 40 ft (12 m) wingspan.[1][2]

The GW-1's wings were extended in 1961 with new tips to 44.5 ft (14 m). The constant-chord wing features a NACA 23018 airfoil and flaps of 25% chord and 22 ft (7 m) span. The aircraft's construction is all-metal, except for the fiberglass nose.[1][2][4]

Only one GW-1 was built and it was registered in the Experimental Amateur-built category.[1][2][3]

Operational history

The GW-1 was used to complete a diamond badge goal flight in 1961.[2]

In July 2011, some 52 years after its completion, the aircraft was still on the Federal Aviation Administration registry and owned by John Coughlin of Del Rio, Texas.[3]
