Parts Needed
• Assembled wing
• Standard size servos with mounting hardware (2)
• Servo extensions (6" or 9") (2)
• Short rods, threaded on one end (2)
• Clevis (2)
• Wire keepers (2)
• Control horn w/backplate (2)
• Control horn mounting screws
• Clevis keepers (2 pieces of fuel tubing 7mm long-not provided)
Tools and Adhesives Needed
• Hobby knife with # 11 blade
• Electrical tape
• Phillips screwdriver
• Drill
• Drill Bit: 1/16"
• Felt-tipped pen
Step 1. Locate the two short rods threaded on one end, two sets
of clevis, and wire keepers. You will also need two control horns,
two control horn backplates, and four mounting screws to mount
the control horns to the aileron control surfaces. 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.
Important: The aileron servo arms should be positioned
outboard toward the wing tips.
Step 3. Thread a 2-56 clevis on the end of one of the threaded
rods. Screw the clevis on 7-10 turns. Install the clevis with wire on
the control horn into the third hole from the mounting base. Be
sure to install the clevis keeper (piece of fuel tubing) over the clevis.
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.
