FLIGHT PREPARATION.
1) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
A) Plug in your radio system per the
manufacturer's instructions and turn every-
thing on.
B) Check the elevator first. Pull back
on the elevator stick. The elevator halves
should move up. If it they do not, flip the servo
reversing switch on your transmitter to change
the direction.
C) Check the rudder. Looking from
behind the airplane, move the rudder stick to
the right. The rudder should move to the right.
!
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.
!
2) Turn on the radio system, and with
the trim tabs on the transmitter in neutral, cen-
ter the control surfaces by making adjust-
ments to the clevises or adjustable servo con-
nectors. The servo arms should be centered
also.
!
3) When the elevator, rudder and aile-
ron 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
surface!
2) Check Control Surface Throw.
A) The Rudder should move 3/4” left
and 3/4” right from center. If it moves too far,
turn the adjustable control horn out away from
the rudder. Do the opposite if there is not
enough throw.
B) Both elevator halves should move
3/8” up and 3/8” down from center. If they move
too far, turn the adjustable control horns out
away from the elevator halves. Do the oppo-
site if there is not enough throw. Both elevator
halves should also travel the same amount
throughout their total movement.
C) The ailerons should move 3/16” up
and 3/16” down from center. If the ailerons
move too much, turn the adjustable control
horns out away from the wing. Do the oppo-
site if there is not enough throw. It is impor-
tant that both ailerons move the same amount,
both up and down.
D) Once the control throws and move-
ments are set, tubing must be added to the
clevises to ensure they do not release in the
air. Cut a piece of fuel line into five 1/4” long
pieces. Unsnap the clevises and slip one
piece over each clevis. Snap the clevises back
in place and slide the tubing up over them.
should move up and the other aileron should
move down. If it does not, flip the servo re-
versing switch on your transmitter to change
the direction.
E) From behind the airplane, look at
the aileron on the right wing half. Move the
aileron stick to the right. The right aileron
D) Check the throttle. Moving the
throttle stick forward should open the carbu-
retor barrel. If it does not, flip the servo re-
versing switch on your transmitter to change
the direction.
If it does not, flip the servo reversing switch on
your transmitter to change the direction.
