1. Using 400 grit sandpaper, fine sand the
balsa sheets before removing the fins. Care-
fully remove all the pieces from the balsa
sheet by freeing the edges with a sharp hobby
knife. Save the scrap wood for step 4.
2. Group the like fins together, and gently
sand the edges as shown in the illustration.
3. Glue the leading edge of the wing onto
the main wing using wood glue.
4. Glue the horizontal tail fins together. The
ends are propped up 1/8 inch to give the cor-
rect amount of dihedral. A piece of scrap balsa
wood under each tip can be used as a spacer.
5. When the glue is dry on the fins, you can
apply sanding sealer to the surfaces of all the
balsa pieces to smooth out the wood. Coat
both sides at the same time to minimize the
chances of the fins warping. Do not allow the
sanding sealer to get on the root edges of the
fins. This could prevent the fins from bonding
well to the body tube when they are glued on
later. Set them aside to dry completely. When
they are dry, sand the sealer smooth until you
get a desirable surface finish. You may need
to repeat this step several times depending on
the level of quality you wish to achieve.
6. Using a razor saw, carefully cut off the
tip on one of the nose cones. The location of
the cut is on the forward side of the raised
bead nearest the tip of the nose cone. You can
discard the tip of the nose. Clean up the end
with sandpaper to make the edge smooth and
free of rough plastic.
7. Using a hobby knife, make a deep
score in the plastic along the groove line on
the shoulder of the piece trimmed in step 6.
After going all the way around the perimeter
with the knife, gently press on the score line
you made. This will cause the plastic to crack
and separate the back half. Discard the rear
portion.
Prop up the tips with scap balsa
wood to give the correct dihedral.
Keep blade on forward
side of the cut line.
