D 2. Cover the fuselage side plan with wax paper. Pin the
die-cut 1/8" ply fuselage side doublers #1 through #7 in
position over the fuselage side plan and use thin CA to glue
the doublers together. Use medium CA to fill in any gaps in
the joints. Build two fuselage side doublers.
D 5. Use medium CA to glue a long sheet and a short
sheet together at the diagonal cut. Make four sheets 1/4" x
3" x 52-112". After the CA cures, edge glue two of the
sheets together to make two 1/4" x 6" x 52-1/2" fuselage
sides. Note: For better strength, place the diagonal joints
at opposite ends of the fuselage sheet. At one end place a
mark 2" from the edge. Then, place a mark 22" from the 2"
mark. At this mark measure in 1" from the edge of the sheet
and place a mark. Cut the fuselage side from the 2" mark to
the 1" mark and then to the edge. Use medium CA to edge
glue this piece at the other end of the fuselage side as
shown in the drawing above.
D 3. Use a sanding bar to sand the fuselage side doublers
smooth. Position the fuselage side doublers next to each
other as shown. At this point you need to determine on
which side the throttle pushrod will be installed in the
fuselage. With the engine held upside-down and viewed
from the rear, note on which side the throttle arm is located.
This will be the same side the rudder pushrod exits the
fuselage. Label the doubler with the rudder slot punched
out the same as the side the throttle arm is on. If the throttle
arm is on the right side, mark the doubler right side. It is
important that you position the fuselage side doublers as
shown above to ensure that you build a right and left side.
Use medium CA to glue a die-cut 1/8" ply wing saddle
doubler #8 to each fuselage side doubler. Make sure the
wing saddle doubler is aligned with the fuselage side
doubler at the wing saddle.
D 4. On four of the 1/4" x 3" x 36" balsa sheets make a
mark 3" from one end. Make a diagonal cut from the mark
to the corner. On the remaining two 1/4" x 3" x 36" balsa
sheets place a mark on one edge 16-1/2" from the end and
on the other edge 19-1/2" from the end. Make a diagonal
cut from the 16-1/2" mark to the 19-1/2" mark.
D 6. Position the fuselage side doubler on the 1/4" balsa
fuselage side with the top edge of the doubler flush with the
edge of the fuselage side. Allow the fuselage side to
overhang the ends. Position the doubler so that the
fuselage side extends past the doubler by 3/8" in front of
the wing saddle and past the aft end of the doubler by
1-1/2". While working on a flat building board, use medium
CA to glue the doublers to the fuselage sides
