8. Center a control horn on the line that you made. Now
slide the horn forward or back until the pushrod holes are
aligned directly above the hinge line.
❏ ❏
9. Use the holes in the base of the
control horn
as a
drilling template. Use a 3/32" [2.4mm] drill bit and drill three
holes in the aileron. Use thin CA to harden the holes that you
drilled.
Note:
Do not use the backing plate as a template. Its
holes must not be drilled.
❏ ❏
10. Install the control horn and its plastic backplate with
three 2-56 x 1" [25mm] machine screws. Cut off the excess
portion of the screw when you’re done.
❏
11. Repeat steps 7 through 10 for each aileron.
❏ ❏
12. Locate the four (4) 3-1/4" [83mm] long aileron
pushrods and four (4) plastic clevises. Thread the clevises
onto the pushrods so that 1/16" [1.6mm] of thread is exposed
on the inside of the threaded barrel of the clevis. Slide a
silicone clevis retainer onto the pushrod.
❏ ❏
13. Attach the clevis to the outermost hole of the
control horn.
❏ ❏
14. Holding the aileron in the neutral position, extend the
pushrod to the third hole out from the center of the servo arm.
Mark the pushrod at the hole. Make a 90° bend at the mark.
❏ ❏
15. Install the pushrod in the third hole out from the
center of the servo arm. Attach a plastic keeper to the
pushrod and cut off the excess portion of the pushrod when
you’re done.
❏
16. Repeat steps 12 though 15 for the remaining ailerons.
