8. Cut a 1/8" groove in the leading edge of both elevators
to accommodate the wire. Hint: Use a Great Planes Groove
Tube
™
Cutting Tool (GPMR8140) or a 1/8" brass tube sharpened
on one end to cut the grooves.
❏
9. Insert the joiner wire into both elevators. Make sure the
elevators lie flat on your workbench. If both elevators do not
lie flat, "tweak" the joiner wire as necessary.
❏
10. Use a bar sander with 80-grit sandpaper to round the
outer edges of all the tail surfaces. Use a razor plane or a
bar sander to bevel the leading edge of the elevators and
rudder to allow for control throw movement. Hint: Do not
make the bevel too sharp. Refer to the cross-section on the
plan to get the correct angle of the bevel.
❏
11. Drill 1/16" or 3/32" holes through both tips of the stab,
and the tip of the fin, rudder and elevators, to vent air that
would otherwise be trapped and expand while shrinking the
covering.

1. Cut four 8-3/4" long sheets from a 3/32" x 4" x 36"
balsa sheet. Follow the Expert Tip below to glue the sheets
together, making a 8-3/4" x 16" skin for the bottom center-
section sheeting.
How to glue together sheeting
A. Use a straightedge to true the joining edges of each
sheet.
B. Tightly tape the sheets together with masking tape.
C. Flip the sheets over and apply aliphatic resin such as
Great Planes Pro Wood Glue between the seams.
D. Place the sheets on your workbench covered with Plan
Protector to keep the glue from sticking to the bench. Use
a squeegee such as an expired credit card or something
similar to wipe off excess glue. Use weights to hold the
sheets down until the glue dries.
❏
2. Make a second 8-3/4" x 16" skin the same way for the
top center-section sheeting. After the glue has dried, remove
the masking tape and sand both skins flat and smooth.
❏
3. Trim one of the center-section skins to a length of 13-3/4".
Place the skin over the center-section of the plan. Align the
