Hawk Classic Single
Place CGS
When the CGS Hawk Classic was introduced to the world at the
Sun-n-Fun Air Show, Lakeland, Fl. in the spring of 1982, it was the
first fully enclosed ultralight. The features of this time honoured
classic were the direct result of a year long market study conducted
by CGS to see what pilot's really wanted in an ultralight. This
survey showed the most desired features were: fully enclosed cockpit
with removable doors (for summer flying enjoyment), full 3 axis
control, true aircraft flaps (not flaperons), strut braced wing and
tail, choice of tricycle gear (with steerable nose wheel) or
taildragger (with steerable tail wheel), and a pusher engine. All of
these are standard features on all CGS Hawk models to this day.
The basic model includes wing struts that are round tubing, and
incorporate jury struts. The wing design has a double surface flat
bottomed airfoil for stable flight characteristics. The nose is
rounded on the bottom and the windshield has a flatter angle than
the CGS Hawk Arrow models. Flaps (not flaperons) are standard
equipment on all Hawks and are very effective in increasing climb
rate and decreasing landing distance. At the heart of the Hawk's
unique design is its curved boom tube (which has never been
successfully copied by any other ultralight manufacturer). The
curved boom allows the horizontal stabilizer to be placed up and
above the down wash of the wing, especially when flaps are deployed.
Another benefit of the curve is shorter landing gear legs making it
easier to get in and out of your plane. The curved boom also is
stronger in torsion than a straight boom, and allows the airplane to
rotate for take offs and landings in a normal fashion without
banging the boom on the ground. It is also aesthetically pleasing to
look at.
