sure the strobe will be straight when mounted. Transfer drill #40 through the aft
set of nut plate rivet holes. Cleco in place. Transfer drill #11 though the center
hole for the nut plate. Rivet a nut plate to the Mount inside the Wing Tip.

Use a Dremel tool to remove Wing Tip material inside the Mount for the wires
and strobe retaining pin.

AILERON AND FLAP ATTACHMENT
1.
Make sure all the bronze flange bushings are in place on the hinges as well as
the hinge arms. This is best after surfaces are painted. Refer to the Parts Manual
Drawing for orientation of the bushings, bolts, and washers.
2.
Place the control surface on the wing in the correct orientation and slide the
hinges over the hinge arms. Make sure the bronze flange bushings stay in place.
3.
Place the bolts through the hinges. Lightly tighten the bolts. Leave the bolts just
loose enough that the control surfaces move freely.
4.
Check for clearance between the aileron and wing. No contact is allowed, trim if
required to have at least 1/16" gap.
5.
To protect the paint finish place a piece of foam pipe insulation on the aileron
hinge arms.
