WINGS:

The wings have designed and made to be a 2-piece system, joined
by the main aluminum blade joiner at the spar box location and a
steel locating pin at the rear. This system has proven to be very
tough and easy to use. An obvious benefit is the fact that the wing
panels can be easily transported or stored, requiring a minimum of
space. Also, you might want to consider using 5-minute epoxy to
permanently install the aluminum blade wing joiner and the rear
steel locating pin into one of the wing panels. Doing this prevents
accidentally losing these parts - your call. Note that the ailerons
have been factory-hinged. Flex them up and down a few times to
loosen them up and they are ready to use.

Last, to avoid

unnecessary dents, dings, or scuffing of the various covered parts,
we suggest that you cover your workbench with a protective
blanket or foam sheet.

For the following steps you will need two standard aileron servos,
two 24” servo extensions and a Dual Servo “Y” Harness for your
particular radio system.

1) The aileron servo bay for each wing panel is located on the

bottom surface, just in front of the aileron. These bays have been
covered over and now need to be opened to allow access. Use a
hobby knife to make four diagonal cuts from each corner of the
servo bay, meeting in the middle.

Use a covering iron to seal the four loose edges of each side of the
servo bay opening and trim the excess covering material with a
hobby knife. Inside the servo bay opening you will find a short
length of wood with a string tied to it. This string is used to pull the
aileron servo lead through the wing and out of the opening in the
bottom of each wing panel - leave it in place for now.

Also, on the bottom of each wing panel, at the center front location,
you will see an oblong opening.

This is the servo lead exit

opening. Inside this opening you will see a piece of wood with a
string tied to it - this is the other end of the string in the aileron
servo bay. Leave the string in place for now.
