PREPARATIONS

❏
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 4.

2. Check the covering on the wing, stabilizer and rudder.
Use a covering iron with a covering sock on medium heat to
tighten the covering if necessary. Apply pressure over sheeted
areas to thoroughly bond the covering to the wood.
ASSEMBLE THE WING

Join the Wing Halves

❏
1. Test fi t the hardwood wing joiner in the two wing halves.
Note that one edge of the wing joiner is fl at and the other edge
is tapered. The fl at edge is positioned towards the top of the
wing. With the wing joiner properly installed both wing tips
should be off of the table. Check that there is no gap between
the two wing halves at the wing root.
❏
2. Insert the 3 × 15mm alignment pin half way into the root
rib of one wing half. Use thin CA to glue it in position.
❏
3. Mix together ½ oz. [15cc] of 30-minute epoxy. Coat the
inside of wing joiner cavity in both of the wing halves. Apply
epoxy to half of the wing joiner and insert it into one of the
wing halves. Apply epoxy to the other half of the wing joiner
and the root rib of both wing halves. Join the second wing
half to the fi rst. Wipe off any excess epoxy with a paper towel
dampened with denatured alcohol. Hold the two wing halves
together with masking tape until the epoxy has cured.
❏
4. Insert the two ¼" × 1" [6 × 25 mm] wood wing dowels
in the leading edge of the wing. Glue the wing dowels to the
wing with thin CA glue.
❏
5. Remove the covering from the two wing bolt holes in
the wing and the wing bolt plate. Position the wing bolt plate
on the bottom of the wing and insert the two 3 × 18mm wing
bolts to hold it in position.
❏
6. Use a fi ne line marker to mark the outline of the wing bolt
plate on the bottom of the wing. Remove the wing bolt plate.
Using a sharp hobby knife cut and remove the covering from
the wing, inside the outline of the wing bolt plate. Do not cut
the balsa wing sheeting.
❏
7. Glue the wing bolt plate to the bottom of the wing using
the wing bolts to align the wing bolt plate with the wing.
