Overview 2

    The CCW-5 retained the fuselage and empennage of the Brigadier, but replaced the whole centre section with a pair of channels, starting at roots in the lower part of the fuselage. Only beyond the channels did the conventional wings regain their mid-wing configuration. A 225 hp (168 kW) Continental O-470 flat six engine was mounted on slender vertical and horizontal struts at the centre of each the channels, on the mid-wing line. These drove constant speed pusher propellers. The main undercarriage was much shortened by mounting its legs on the outer part of the channel section; the Brigadier nosewheel was retained.

    The first of two CCW-5s flew on 13 July 1953, piloted by Walker Davidson, at Oxnard, California and was reported to have completed its test flying by autumn 1956, when production was scheduled to begin. This did not happen, though a second aircraft flew in June 1964. The delay was partly the result of financial problems, though the CCW-5 performed well below the original estimates, with a maximum achieved speed of 220 mph (354 km/h) compared with an estimated 300 mph (480 km/h). It was claimed that the aircraft could fly under control at 11 mph (18 km/h) and that it could take off with a 1,500 lb (680 kg) load at 70% power in 90 ft (28 m).

    The second CCW-5 was finished in 1964 with 260 hp (194 kW) Continental IO-470P engines; it survives and is under restoration at the Mid-Atlantic Air Museum, Reading, Pennsylvania.
