GET READY TO BUILD
1. Unroll the plan sheets. Re-roll them inside out to make
them lie flat. NOTE: You may cut the fuselage plan into two
sections for case of building on the "Bottom View," by
cutting along the "cut line" shown on the plan.
2. Remove all parts from the box. As you do, figure out
the name of each part by comparing it with the plans and the
parts list. Using a felt tip pen, write the part name or size on
each piece to avoid confusion later. Use the die-cut patterns
shown on page 5 to identify the die-cut parts and mark them
before punching out. Save all scraps. If any of the die-cut
parts are difficult to punch out, do not force them! Instead,
first cut around the parts with an Xacto knife. After punching
out the die-cut parts, use your T-Bar or sanding block to
lightly sand the edges to remove any die-cutting irregulari-
ties.
3. As you identify and mark the parts, separate them into
groups, such as fuse (fuselage), wing, fin and stab (stabi-
lizer), and hardware.
"TAIL FEATHERS"
glue the fin front to the fin rear, then glue on the fin tip. Sand
the front of the fin tip to blend with the fin, as shown on the
plan.
4. Using a T-bar or sanding block, sand both sides of
the fin smooth. Then sand the leading edge and top edge to
a rounded shape, as shown on the plan. Draw a centerline
along the trailing edge of the fin to mark the hinge line.
5. Glue the rudder front to the rudder rear. then glue
on the rudder bottom and rudder end.
6. Draw a centerline all around the edges of the rudder.
7. Using a sanding block and coarse (50 or 80-grit)
BUILD THE FIN AND RUDDER
1. Find the following parts: 5/16" balsa fin front, fin
rear, rudder front, rudder rear and rudder bottom. Compare
the parts to the plans to make sure you have the correct parts.
Also find the 5/16" x 5/8" x 5-3/4" balsa stick, and the 1/8" x
3/8" x 11-7/8 "balsa stick.
sandpaper, sand both sides of the rudder to a taper as shown
on the plans. The trailing edge should end up approximately
1/8" wide and have a rounded shape. (Do not sand to a sharp
edge). Sand the bottom edge to a rounded shape. Sand the
leading edge to a "V-shape" as shown on the plan.
8. Hold the fin and rudder together and mark the fin tip
2. Cut the 1/8" x 3/8" x 11 -7/8" balsa stick into 5 pieces
having lengths of: 2-7/8", 2-7/8", 1-5/8", 1-5/8" and 2-3/4".
The 2-3/4" length is the rudder end. The remaining pieces
are the elevator ends.
at the rudder trailing edge. Cut off the fin tip and sand it to
match the rudder as shown on the plan.
9. If you are building a'' taildragger'', check the plans
and mark the location of the tailgear on the rudder. Drill a
