Required Parts
• Wing assembly • Control horn (2)
• Mounting screws (6) • Metal clevis (4)
• Clevis keeper (4) • 4-40 x 2" threaded rod (2)
• 4-40 nuts (4) • #2 x 3/8" screws (6)
Required Tools and Adhesives
• Thin CA • Phillips screwdriver
• Drill Bit: 1/16", 5/64" • Drill
• Felt-tipped pen
Step 1
Prepare the 4-40 aileron linkage by placing the clevis
keepers onto the metal clevises. Thread a 2-56 nut onto
each end of the 4-40 x 2" threaded rod. Thread a clevis
onto each end of the threaded rod. The threaded rod
should just be visible between the forks of the clevis.
Step 2
Attach the assembled control linkage to the
aileron servo arm.
Step 3
Remove the back plate from the control horn using side
cutters or a sharp hobby knife. Use a 5/64" drill bit to drill
out the mounting holes in the control horn.
Step 4
Position the control on the aileron by aligning the holes
of the control horn with the hinge line of the aileron and
center on the horn mounting plate (as marked back in
Section 1). Use a felt-tipped pen to transfer the mounting
holes from the control horn onto the aileron.
