Section 4: Installing the Aileron Linkages

Parts Needed
• Wing/fuselage assembly
• Short rods, threaded on one end (2)
• Clevis (2)
• Control horn (2)
• Control horn mounting screws
• Clevis keepers (2 pcs of fuel tubing 7mm long)(not provided)
Tools and Adhesives Needed
• Medium Phillips screwdriver
• Drill
• Drill Bit: 1/16"
• Felt-tipped pen
• Z-bend pliers
Step 1. Locate the short rods threaded on one end, clevis, and
keepers. You will also need a control horn, control horn back-
plate, and mounting screws to mount the control horn to the
control surface. The instructions will refer to construction of just
one linkage and control horn. Assembly and installation for the
other aileron will follow this same sequence.

Step 2. Before assembly and mounting the linkages/control
horns, it's a good idea to center the aileron 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. It's important that
the mechanical adjustments are made as closely as possible
before attempting to make any electrical adjustments through
the transmitter programs.

Step 3. The control horn should be positioned so the holes
that the clevis connects onto are over the centerline of the hinge
line of the control surface. Once satisfied with the horn location
(it should be a straight line from the servo arm to the horn),
mark the location with a felt-tipped pen.
Step 4. Using a 1/16" drill bit, drill the screw holes for
mounting the control horn.
Step 5. Attach the control horn to the aileron using the screws
and the control horn backplate. Be careful not to accidentally
puncture the covering with the screwdriver.
