BUILDING INSTRUCTIONS

Preparations

1. If you have not done so already, remove the major
parts of the kit from the box (wings, fuselage, cowl, tail
parts, etc.) and inspect them for damage. If any parts are
damaged or missing, contact Product Support at the
address or telephone number listed in the front cover.
2. Remove the masking tape and separate the ailerons
from the wing and the elevators from the stab. Use a
covering iron with a covering sock on high heat to tighten
the model's covering if necessary. Apply pressure with a Hot
Glove over sheeted areas to thoroughly bond the covering
to the wood.

ASSEMBLE THE WING

Hook Up the Ailerons

1. The first steps in the construction of this wing will be
the installation of the ailerons and the aileron servos. The
process described here will explain how to install the right
aileron and the right aileron servo. The process has to be
repeated again to install the left aileron and the left aileron
servo, or you can work on both at the same time.
DRILL A 3/32" HOLE
1/2" DEEP, IN CENTER
OF HINGE SLOT
2. Locate the pre-cut hinge slots on the wing's trailing
edge and the leading edge of the aileron. Drill a 3/32"
[2.4mm] hole, 1/2" [12mm] deep in the center of each hinge
slot to allow the CA to "wick" in. Follow-up with a #11 blade
to clean out the slots. Hint: If you have one, use a high-
speed rotary tool to drill the holes.
3. Use a sharp #11 blade to cut a strip of covering
from the hinge slots in the wing and aileron.
4. Cut five 3/4" x 1" [19mm x 25mm] hinges from the
CA hinge strip. Snip off the corners so they go in easier.
5. Test fit the ailerons to the wing with the hinges. If
the hinges do not remain centered, stick a pin through the
middle of the hinge to hold it in position.
6. Remove any pins you may have inserted into the
hinges. Adjust the aileron so that there is a small gap
between the LE of the aileron and the wing. The gap should
be small–just enough to see light through or to slip a piece
of paper through.
7. Apply six drops of thin CA to the top and bottom of
each hinge. Do not use CA accelerator. After the CA has
fully hardened, test the hinges by pulling on the aileron.
