12. Use a 6-32 tap to clear the threads if the screws do not
thread in easily.
13. Attach the top wing center section to the cabane struts
using four 6-32 x 1/2-inch socket head cap screws. Use
thread lock on all the screws. Once the center section
is attached, tighten all the cabane screws inside the
fuselage.
14. Route a 48-inch (1220mm) servo extension through the
opening in the center section and through the cabane
strut cover. Use low-tack tape to hold the extension in
position while routing it into the fuselage.
15. Route the extension on the inside of the cabane strut
and through the slot in the fuselage near the cabane.
The extension will then be routed down into the fuselage
through the openings in the formers to the location for
the receiver.
16. Position the servo lead so the cover can be positioned
against the wing panel. Use clear tape to secure the
extension to the cabane strut. The rear cabane cover can
then be glued into position using canopy glue.

BOTTOM WING INSTALLATION
1. Slide the wing tube into the bottom wing panel. The tube
will slide in easily, so don't force it more than it will slide
easily.
2. Slide the anti-rotation tube into the bottom wing as well.
3. Slide the wing into position on the fuselage. Guide the
aileron servo extension into the opening.
4. Slide the wing tightly against the fuselage. Use two 6-32
x 3/4-inch socket head cap screws and two #6 washers
to attach the wing to the fuselage. Use a 7/64-inch hex
wrench to tighten the screws.
