gear and trim the covering away.

5/8" [16 mm] SHCS and six #6 lock washers Apply thread-

not to push the pre-installed blind nuts out of the landing gear
mounting rails when threading in the socket head cap screws.

1. Just as you did with the ailerons and rudder, prepare
the hinge point holes in the stabilizer and elevators by test
fitting the hinges and enlarging the holes as necessary.
❏
2. Locate the stabilizer slots near the aft end of the
fuselage and trim away the covering. Seal the edges of the
slots with a trim iron.

3. You will need to temporarily install the wing panels in
order to align the stabilizer in the fuselage. Slide the black
aluminum wing tube into the fiberglass joiner tube inside
the fuselage and center its position.
❏
4. Fit the wing panels onto the wing tube, pushing them
into the fuselage until the root ribs are pressed against the
inner fuselage formers. The anti-rotation pins will fit into
receiving holes in the fuselage. Use the included nylon wing
bolts to draw the wing panels in tight.
