7.Trim the covering just inside your lines. Wipe away the lines
with alcohol and glue the wing bolt plate to the wing. Continue
the wing bolt holes through the wing bolt plate with a 5/32"

clean-edged holes in the backplate.

1. Locate and remove the covering away from the
fuselage for the horizontal stabilizer and vertical fin.

2. In order to properly align the stab in the fuse, the wing will need
to be temporarily installed. Attach the wing using two 3mm x 25mm
Phillips machine screws and two 3mm flat washers.
❏
3. Insert the stab into the fuse. Position the stab so it is
centered left and right in the fuse and the tips of the stab are
an equal distance from the wing tips. Trace around the stab
where it meets the fuse with a felt-tip pen.

Elevator & Vertical Fin
BUILD THE FUSELAGE
Use a straightedge to guide the soldering iron at a rate that will
just melt the covering and not burn into the wood. The hotter
the soldering iron, the faster it must travel to melt a fine cut.
Peel off the covering.
HOW TO CUT COVERING FROM BALSA
Use a soldering iron to cut the covering from wing. The tip of
the soldering iron doesn’t have to be sharp, but a fine-tip does
work best. Allow the iron to heat fully.
