4. The pushrods should also be installed correctly into the
control horn. Remember that in step 5, page 10, the rudder
and elevator control rods were installed on the rudder and
elevator control horns using the second hole from the servo
arm center. After connecting the pushrods to the horns,
remove the labels.
5. View the elevator and stab from the end. The elevator
should be centered as shown in the photo above. If the
elevator is not centered with the stab, disconnect the clevis
from the elevator control horn. Holding the end of the
pushrod with pliers, screw or unscrew the clevis as
necessary until the elevator is centered when reconnected
to the pushrod.
6. Center the rudder and ailerons by adjusting the
clevises on the pushrods as necessary.
7. Once the rudder is centered, if necessary, center the
nose wheel by loosening the screw in the screw-lock
pushrod connector on the rudder servo arm. Move the
pushrod forward or back to center the wheel. Securely
tighten the screw and then push the airplane forward on a
flat surface to verify that the airplane rolls straight.
