1 . Thread a nylon clevis 20 complete turns onto
a 4" [152mm] pushrod . Slide a silicone clevis retainer
onto the clevis and connect the clevis to the outer
hole of a nylon control horn .
o o
2 . Position the control horn over the plywood
plate in the aileron (if you cannot see it, hold the aileron
at a shallow angle in good lighting or use a small pin
to puncture the covering) using the position of the
servo arm as a guide . Align the holes in the control
horn directly over the aileron hinge line and mark the
location of the control horn mounting holes .
o o
3 . Drill 1/16" [1 .6mm] holes at the marks you
made through the plywood plate . Do not drill all
the way through the aileron! Thread a #2 x 3/8"
[9 .5mm] self-tapping screw through each hole and
back it out . Apply a couple drops of thin CA glue to
each hole to harden the wood . When the glue has
dried, install the control horns onto the aileron using
two #2 x 3/8" [9 .5mm] self-tapping screws .
o o
4 . Use tape or a small clamp to hold the aileron
in the neutral position . Make a mark on the pushrod
where it crosses the outer hole in the servo arm .
Make a 90 degree bend at the mark on the pushrod
