10. Using a pushrod as a guide, place a large control
horn onto the aileron offset 1/8" [3 mm] towards the wing tip
and make a mark at each control horn mounting hole. Drill
1/16" [1.6 mm] holes at the mark.
❏ ❏
11. Thread a #2 x 1/2" [13 mm] SMS screw into each
hole and back it out. Add a couple drops of thin CA to the
holes to harden the wood. Secure the control horn with two
#2 x 1/2" [13 mm] SMS screws.

12. Install a silicone clevis retainer and a nylon clevis
onto a 12" [305 mm] pushrod. Thread the clevis 14 complete
turns onto the pushrod.
❏ ❏
13. Connect the clevis to the third hole of the aileron
control horn. Line the pushrod up with the servo horn while
holding the aileron in the neutral position. Make a mark on the
pushrod where it intersects the outer hole of the servo horn.
❏ ❏
14. Make a 90° bend at the mark and cut off the excess
pushrod 1/4" [6 mm] beyond the bend. Hook the bend in the
wire to the outer hole of the servo horn and secure it with a
nylon FasLink. Slide the silicone clevis retainer over the
clevis up to the control horn.
