1939: National Aircraft Corp (fdr: Willard R Custer), Hagerstown MD. 1951: Construction by Baumann Aircraft Corp, Santa Barbara CA.
CCW-1 1942 = 1pCmwM; two 75hp Lycoming O-145. Willard Custer; US patent #1,708,720 in 1929. Experiment in a half-barrel STOL wingform based on, in Custer's words, aerophysics as opposed to aerodynamics: "The CCW is an aircraft, not an airplane. It does not plane the air to fly... rather it brings the air to the lift surfaces, and reduces pressure in order to fly at 8 to 11mph." POP: 1; ff: 11/12/42 (p: Willard Custer), in a solo flight that was quite unintentional. Custer, a non-pilot, taxied the plane in a demonstration for financial backers, and suddenly became airborne. A hard landing that followed, collapsing one gear, did not dampen his backers' enthusiasm.
CCW-2 1948 = Evolution of CCW-1 as a test bed used an uncovered Taylorcraft BC-12 fuselage. POP: 1 [N1375V]; ff: 7/3/48 (p: Harold Custer). Flown for about 100 hours of testing, with take-offs and landings made in 45' to 65'. Despite the claim of flying "better than conventional aircraft," it was calculated that a stock Piper Cub was more efficient, lifting 18lbs/hp versus the Channel Wing's 11lbs/hp.
Custer CCW-2 / CCW-5 [N1375V] / [N6257C] (Eaton Chronicles / Bob O'Hara coll)
CCW-5 (Baumann Corp) 1951 = 5pCmwM rg; two 225hp Continental O-470 pusher; span: 41'2" length: 28'9" load: 2400# v: 220/180/15 (>original est: 300/260/x) range: 1680 ceiling: 20,000'. The final version of Custer's STOL theory used a Baumann Brigadier fuselage and tail group; ff: 7/13/53 (p: Walker J Davidson). POP: 2, [N6257C, N5855V], the second of which was built in 1964. Although several firms expressed interest in producing the plane, all failed to provide funds because of various financing difficulties.

Did Escher design the tail on the single engine UAV?
