1. If you have not done so already, remove the major
parts of the kit from the box and inspect for damage. If any
parts are damaged or missing, contact Product Support at
the address or telephone number listed in the
“Kit
Inspection” section on page 6.
❏
2. Remove the tape and separate the ailerons and flaps
from the wing and the elevators from the stab. Use a
covering iron with a covering sock on high heat to tighten the
covering if necessary. Apply pressure over sheeted areas to
thoroughly bond the covering to the wood.
Do the right wing panel first so your work matches the
photos the first time through.
❏ ❏
1. Drill a 3/32" hole, 1/2" [13mm] 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.
❏ ❏
2. Use a sharp #11 blade to cut a strip of covering from
the hinge slots in the wing and aileron.
❏ ❏
3. Cut twelve (12) 1" x 1" [25 x 25mm] hinges from the
CA hinge strip. Snip off the corners so they go in easier.
❏ ❏
4. Test fit the right aileron to the wing with four hinges.
If the hinges don’t remain centered, stick a pin through the
middle of the hinge to hold it in position.
❏ ❏
5. Remove any pins you may have inserted into the
hinges. Adjust the aileron so 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.
❏ ❏
6. 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.
