Hawk
Arrow
two place
The Hawk Arrow series was originally designed as an updated version
of the Hawk Classic, incorporating features requested over a period
of years. The nose section is longer, more pointed, and angles
downward (steeper) than what you find in the Hawk Classic. This
allows for better forward visibility at low sun angles. The nose
also has a flatter floor section. Since the nose was made longer,
the area of the rudder and vertical stabilizer were increased in
order to enjoy the same excellent yaw stability of the Hawk Classic.
The tail boom was also reinforced to handle the loads of this larger
tail assembly.
The Hawk Arrow Two Seat wing has the same semi symmetrical airfoil
as the Hawk Sport, and streamlined extruded aluminum wing struts.
Standard features of the Hawk Arrow also include curved overhead and
curved windshield. This model is for those who like the more modern
jet plane look, yet still want the excellent flying characteristics
of the Hawk Classic. Primarily it’s a personal preference, some
folks seem to like the smoother rounder lines of the Classic while
others like the more modern jet plane look of the Arrow. Either way
they all have the same excellent flying characteristics.
The Hawk Arrow Two Seat incorporates tandem seating rather than side
by side. This allows a student to feel as if he is flying in a
single place during his all important instructional phase because
the instructor is out of sight and behind him. When it is time to
solo, the student pilot experiences more confidence and less stress
with this seating arrangement. He is not suddenly dealing with an
empty seat next to him. With tandem seating, turns to the left or
right are equally comfortable because you don't have to look across
a seat to check behind you. In addition, since most ultralight
aircraft are pushers, the tandem configuration allows for better
inflow to the propeller, and much less drag. Center of gravity
changes are also much less pronounced when flying solo vs. with a
passenger. In a tandem set up, the front pilot balances the engine,
and the passenger sits on the center of gravity, so it makes no
difference if you have a passenger or not. The center of gravity
changes very little. In a side by side arrangement, however, when
the passenger exits the plane, the center of gravity makes a drastic
shift to the rear, and must be compensated for in some way.
On the Hawk Arrow Two Seat the rear seat is designed to sit slightly
higher than the front seat so the field of vision of the passenger
or instructor in the rear seat is not obstructed. 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.
