SPARROW HAWK
Instruction Manual

2)
Turn on the radio system, and with the
trim tabs on the transmitter in neutral, center
the control surfaces by making adjustments
to the clevises or adjustable servo connectors.
The servo arms should be centered also.
1)
We highly recommend setting up the
SPARROW HAWK
using the control throws
listed at right. We have listed control throws
for Low Rate (initial test flying/sport flying).
CONTROL THROWS.
3) When the elevator, rudder and aileron
control surfaces are centered, use a ruler and
check the amount of the control throw in each
surface.
The control throws should be
measured at the widest point of each sur-
face!
FLIGHT PREPARATION.
4) By moving the position of the adjust-
able control horn out from the control surface,
you will decrease the amount of throw of that
control surface. Moving the adjustable con-
trol horn toward the control surface will in-
crease the amount of throw.

When balanced correctly, the airplane should
sit level or slightly nose down when you lift it
up with your fingers.
Bolt the wing to fuselage.
ATTACHMENT WING - FUSELAGE.
To correct this, move the battery and receiver
forward or if this is not possible, stick weight
onto the firewall or use a brass heavy hub spin-
ner hub.
BALANCING.
1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash. The cen-
ter of gravity is located
10 cm
back from the
leading edge of the wing, measured at the
wing tip.
Wing bolt.
Silicon glue.
Machine screw 2 x 8 mm.
2) If the nose of the plane falls, the plane
is nose heavy. To correct this first move the
battery pack further back in the fuselage. If
this is not possible or does not correct it, stick
small amounts of lead weight on the fuselage
sides under the horizontal stabilizer. If the tail
of the plane falls, the plane is tail heavy.
Silicon glue.

A) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
