CGS Hawk
The CGS Hawk is a family of high wing, strut-braced, pusher configuration, single and two-seats-in-tandem ultralight aircraft, designed by Chuck Slusarczyk and manufactured by CGS Aviation.
Development
Designer Chuck Slusarczyk established himself as a hang glider designer in the early 1970s, including producing engine power units for hang gliders. In October 1979, his company, Chuck's Glider Supplies was renamed CGS Aviation. In 1980 Slusarczyk surveyed pilots at Sun 'n Fun and AirVenture to find out what they wanted in a new ultralight aircraft design. The survey revealed pilots were looking for:- an enclosed cockpit with removable doors
- three axis controls
- flaps and not flaperons
- struts in place of cable-bracing
- the choice of tricycle gear, with a steerable nose wheel or conventional landing gear, with a steerable tail wheel
- pusher configuration
The Hawk wing is strut-braced, constructed from aluminum tubing and covered with either pre-sewn Dacron envelopes or doped aircraft fabric. The flat-bottomed wing also features flaps. The fuselage is of similar construction and uses a curved boom tube for its main structural member. The curved tube allows the tail to be located higher, out of the wing's downwash, especially when the flaps are extended. Landing gear for all models is optionally tricycle or conventional.
The Hawks are available as aircraft kits, quick-build kits, or completed aircraft.
