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.

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)
(aerobatic 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!
When balanced correctly, the airplane should
sit level or slightly nose down when you lift it
up with your fingers.
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.
2) If the nose of the plane falls, the plane is
nose heavy. To correct this first move the bat-
tery 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.
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 locate
