Dynaflite DYFA2016 - Manual (Page 12)

U 15. Make sure the front of the fuselage sides, top
and bottom are flush with the front bulkhead D.
Securely glue the balsa nose block in position with
medium or thick CA.
U 16. Shape the nose block with a razor plane or a
hobby knife, followed by progressively finer grits of
sandpaper, to match the contour of the fuselage
shown on the plan.
U 17. If you have drilled holes in bulkheads A and B
for the antenna guide tube, install the guide tube. Cut
a hole in the bottom of the fuselage near the aft end
so the guide tube can exit. Glue the tube in position.
Fill the gaps around the tube at the exit and sand it
flush with the bottom sheeting after the filler dries.
Q 1. Position the rudder portion of the plan over
your building board. Cover it with wax paper.
Q 2. Use the remainder of the 3/16" x 1/4" x 24"
balsa s t i c k you used to build the f i n and an
additional 3/16" x 1/4" x 24" balsa stick, to build
the rudder framework. Cut the pieces to the correct
length. Pin them in their location over the plan and
glue them together with medium CA.
IJ 3. Use the remainder of the 3/16" x 1-3/8" x
24" balsa sheet you also used for the tip of the fin to
make the base of the rudder. Glue the base in
position with medium CA.
Q 4. Cut the rudder ribs from the remainder of the
1/16" x 3/16" x 24" balsa stick you originally used
for the fin ribs. Glue them in position with medium CA.
U 5. Remove the T-pins. Lift the rudder from the
plan and peel off the wax paper. Lightly sand the
rudder to remove any glue bumps and high spots. If
you use a sanding block, be careful not to snag the
1/16" ribs with the edges of the sandpaper.
Q 6. Round the bottom of the rudder as shown on
the plan. Taper the rudder toward the trailing edge
to a thickness of approximately 3/32" or round the
trailing edge the same as the leading edge of the fin.
Perform steps 7, 8 and 9 only if you are going to
build a functional rudder.
U 7. Cut the hinge slots in the rudder in the location
shown on the plan. Shape the leading edge of the
rudder to a "V" as shown on the plan.
