1. Unroll the plan sheets, then re-roll the plans inside-out to
make them lie flat.
2. Sort through the sticks and sheets, grouping them by
size. Masking tape can be used to bundle matching sheets
and sticks. Using a felt tip or ballpoint pen, lightly write the
part name or size on each piece or bundle. Refer to the
parts list and plans for sizes and quantities. Use the die-cut
patterns shown on page 6 to identify the die-cut parts and
mark them before removing them from the die sheet. Save
all leftovers. If any of the die-cut parts are difficult to remove,
do not force them! Instead, cut around the parts with a
hobby knife or lightly sand the back of the sheet. After
removing the die-cut parts, use your sanding block to lightly
sand the edges to remove any die-cutting irregularities.
3. As you identify and mark the parts, separate them into
groups, such as fuse (fuselage), wing, fin, stab (stabilizer)
and hardware.
Zipper-top food storage bags are handy to store the small
parts as you sort, identify and separate them into
sub-assemblies.
4. Work on a flat surface. Cover the plans with waxed paper
or Great Planes Plan Protector to prevent glue from sticking
to the plan.
5. When instructed to test fit parts, this means DO NOT USE
GLUE until you are satisfied that everything fits properly --
THEN glue the parts together if instructed to do so.
6. Whenever the instructions tell you to glue pieces
together, use CA. When a specific type of glue is required,
the instructions will state the type of glue that is highly
recommended. When 30-minute epoxy is specified, it is
highly recommended that you use only 30-minute (or
slower) epoxy because you will need either the working
time and/or the additional strength.
7. The easiest way to cut balsa sticks is with a single-edge
razor blade or razor saw. Position the stick over the plan,
mark its size, then cut the part on a cutting mat. A modeling
miter box works well for cutting square corners and 45-
degree gussets.
