7. When you are satisfied with the responses,
replace the center screw back into the throttle servo.
RUDDER SERVO
The same Tx stick that regulates the throttle, when the
stick is moved up and down, also moves the rudder and
the nosegear steering, when the stick is moved to the right
or to the left. The stick will spring back to the center posi-
tion when it is released. Also, note that under the
rudder/throttle stick is another trim tab. This trim tab
moves from right to left and will help center the rudder and
keep it in place.
1. Move the rudder trim tab into the center of
its movement range.
2. Remount the servo wheel onto the servo,
making sure the wheel placement allows the pushrods to
be centered on the servo, just as they were earlier, when
the pushrods were mounted.
3. Hold the rudder stick to the left and see if
the rudder trailing edge, when viewed from behind the
plane, has moved to the left. If it has moved to the right,
then push the servo-reversing switch to correct the move-
ment.
4. Once the rudder is correctly responding to
the stick movements, look down from the top of the rud-
der/fin and make sure they are in a straight line with each
other. If not, adjust the snap link in or out on the pushrod
that is hooked to the rudder control horn.
The rudder should move approximately ½"
to each side of center when the transmitter stick is moved.
If your rudder needs more movement, move the snap link
on the control horn toward the inside holes.
When all adjustments have been made,
replace the center screw into the servo wheel.
5. The nosegear must also be centered. If
adjustments are necessary, loosen the setscrew in the
steering arm and twist the nosegear until it is straight.
When satisfied, retighten the setscrew.
ELEVATOR SERVO
The right stick on the transmitter controls the elevator
servo. Pulling down on this stick will make the plane climb
and pushing up on the stick will put the model into a dive.
1. Move the trim tab to the right of the stick,
so that it is centered
2. Remount the servo wheel onto the servo,
making sure the wheel placement allows the pushrod to be
centered on the servo, just as it was earlier, when the
pushrod was mounted.
3. Pulling down on the stick should cause the
elevator to point up. If it goes down, use your reversing
switch to correct the problem.
4. View the edge of the stab and the elevator
to see that they are in a straight line with each other. Twist
the snap link on the elevator control horn in or out, to
adjust the elevator level with the stab.
5. The full range of elevator movement is
approximately 3/8" up and 3/8" down. If more movement
is needed, move the snap link on the control horn toward
the inside holes.
6. When all necessary adjustments have
been made, replace the center screw into the servo wheel.
AILERON SERVO
The same stick that moves the elevator also controls the
ailerons. Moving this stick to the right or left will turn the
aircraft to the right or left. The aileron trim tab, located
beneath the aileron stick, helps the model maintain
straight, level flight.
1. Move the aileron trim tab to the center
position.
2. Remove the center screw and the servo
arm.
3. With the wing resting up against the fuse-
lage, plug the aileron servo into the extension wire coming
out of the receiver.
4. Remount the servo arm onto the aileron
servo, making sure the arm placement allows the pushrods
to be centered on the servo, just as they were earlier,
when they were mounted.
5. Set the wing on the fuselage, by do not
secure it with rubber bands.
6. Holding the aileron stick to the left, check
to see that the left aileron trailing edge is pointing up and
the right aileron trailing edge is pointing down. If your
ailerons are reversed, use your servo-reversing switch to
make the correction.
7.
The correct range of motion for the
ailerons is approximately ¼" up or down. If more move-
ment is needed, screw the adjustable horn brackets (into
which the snap links are hooked) down on the wires,
toward the wing.
8.
When all adjustments have been made,
replace the center screw into the servo arm.
