4) 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. To
correct this, move the battery and receiver
forward orif this is not possible, stick weight
onto the firewall. When balanced correctly, the
airplane should sit level or slightly nose down
when you lift it up with your fingers.
PREFLIGHT CHECK.
1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
2) Check every bolt and every glue joint
in the
PC-9
to ensure that everything is tight
and well bonded.
We wish you many safe and enjoyable
flights with your PC-9.
8) Properly balance the propeller. An out
of balance propeller will cause excessive vi-
bration which could lead to engine and/or air-
frame failure.
3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
4) Check the control surfaces. All should
move in the correct direction and not bind in
any way.
5) If your radio transmitter is equipped
with dual rate switches double check that they
are on the low rate setting for your first few
flights.
6) Check to ensure the control surfaces
are moving the proper amount for both low
and high rate settings.
7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.
CONTROL THROWS.
1) We highly recommend setting up the
PC-9
using the control throws listed below. We
have listed control throws for both initial test
flying/sport flying and aerobatic flying.
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.
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!
INITIAL FLYING/SPORT FLYING
Ailerons:
3/16” up
3/16” down
Elevator:
5/16” up
5/16” down
Rudder:
3/4” right
3/4” left
AEROBATIC FLYING
Ailerons:
3/8” up
3/8” down
Elevator:
5/8” up
5/8” down
Rudder:
1-1/4” right
1-1/4” lef
t
Do not use the aerobatic settings for
initial test flying or sport flying.
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.
8-9.5cm.
