Parts Needed Tools and Adhesives Needed
Step 1. Locate the short rods threaded on one end, clevis and
wire keepers. You will also need a control horn, a control horn
backplate, and mounting screws to mount the control horn to the
control surface. Instructions will refer to construction of just one
linkage and control horn. Assembly and installation for both
ailerons and/or all four will follow this same sequence.
Step 2. Before assembly and mounting the linkages/control
horns, it’s a good idea to center the wing servos. Connect them
to the receiver, turn on your transmitter, then the receiver. Once
the servos have moved to their electrical center, you can
position the servo control arm so that it will be approximately
90 degrees to the linkage when it’s attached. Fine-tuning of the
servo arm position can be done by adjusting the linkages in or
out. It’s important that the mechanical adjustments are made as
closely as possible before attempting to make any electrical
adjustments through the transmitter programs.
Important: The aileron/flaps servo arms should be posi-
tioned outboard toward the wing tips as shown below.
Failure to do this can cause radio programming diffi-
culties that will result in the flaps or ailerons moving
in the wrong direction.
Note: If you are using a Y-harness to connect servos to
receiver and if you are setting up a quad/flap
configuration, refer to the radio set-up section
of this manual for further instruction on position of
the servo control arms.
