Carpenter Special

The Carpenter Special was a custom homebuilt design from Wilbur Staib, built for M. Carpenter in Joplin, Missouri in 1933.

The Carpenter Special is an open cockpit biplane with conventional landing gear. The fuselage is made of welded steel tube and the wings use wooden spars and wing ribs, all with fabric covering. The aircraft was built with a Continental A-50 powerplant, but was re-engined in 1949 with a 125 hp (93 kW) Warner Scarab, then with a Continental C-85 engine of 85 hp (63 kW).^[1]
