The Custer CCW-5 was a twin-engined, 5-seat aircraft of pusher configuration, which used a channel wing claimed to enable low speed flight and short take-offs.

In most situations an aircraft's lift comes chiefly from the low pressure generated on the upper surface by the locally enhanced higher air velocity.

A 225 hp (168 kW) Continental O-470 flat six engine was mounted on slender vertical and horizontal struts at the center of each the channels, on the mid-wing line.

The main undercarriage was much shortened by mounting its legs on the outer part of the channel section; the Brigadier nosewheel was retained.

[2] The second CCW-5 was finished in 1964 with 260 hp (194 kW) Continental IO-470P engines;[4] it survives and is under restoration at the Mid-Atlantic Air Museum, Reading, Pennsylvania.
