Section 19: Fine Tuning the Control Linkages

The initial set-up of the control linkages may require some
minor adjustments.
Also, if such components as a servo are replaced, it may be
necessary to make adjustments to the control throws. In either
case, the following steps are provided as a guide in making
adjustments to the various controls of your aircraft. It will be
helpful to make sure your servos are electrically centered
(electrical neutral or "0") before you begin making any linkage
adjustments. Refer to Section 14, Steps 12 and 13 for
instructions on how to electrically center the servos.
Ailerons
1. With the radio turned on and the aileron servo plugged into
the aileron channel (or aileron extension if used), move the
aileron stick (the right stick) all the way to the right.
2. The aileron servo horn should rotate in such a direction as to
cause the right aileron to move up approximately 3/8'' and the
left aileron to move down approximately 3/8'', measured at the
trailing edge of the aileron. Note: Aircraft orientation is as if you
are sitting in the cockpit looking forward.
3. If the ailerons do not move in the correct direction, switch the
aileron servo reversing switch on the transmitter.

4. If the ailerons do not move far enough, either move the
pushrods out on the servo horn (farthest hole from center, both
sides), or move the torque rod horns down farther on the aileron
torque rods. Moving the torque rod horns closer to the wings
increases aileron throw.
Elevator
5. With the elevator servo in its electrical zero or centered
position, make sure the servo horn is 90-degrees to the center
line of the aircraft. Adjust the clevis until the elevator is in its
neutral position (no up or down). Make sure to remember to
center the elevator trim on your transmitter.
6. With the radio system turned on, move the elevator stick (the
right stick) upward (away from you, down elevator). The elevator
should move down approximately 1/2'' measured at the trailing
edge of the elevator.
3/8''
7. If the elevator moves up, switch the elevator servo reversing
switch on the transmitter.
