FLIGHT PREPARATION.

A) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
B) Plug in your radio system per the
manufacturer's instructions and turn every-
thing on.
C) Check the elevator first. Pull back on
the elevator stick. The elevator halves should
move up. If it they do not, flip the servo re-
versing switch on your transmitter to change
the direction.
D) Check the rudder. Looking from be-
hind the airplane, move the rudder stick to the
right. The rudder should move to the right. If it
does not, flip the servo reversing switch on
your transmitter to change the direction.
E) Check the throttle. Moving the throttle
stick forward should open the carburetor bar-
rel. If it does not, flip the servo reversing switch
on your transmitter to change the direction.
F) From behind the airplane, look at the
aileron on the right wing half. Move the aileron
stick to the right. The right aileron should move
up and the other aileron should move down. If
it does not, flip the servo reversing switch on
your transmitter to change the direction.
We wish you many safe and enjoyable
flights with your YAK 55.

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 YAK 55 to ensure that everything is tight
and well bonded.
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.
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.
