parts (SKY6S02 and SKY6S03) and the 3/16" x
3/4" x 24" balsa sticks (SKY6S05) Use the
hardest 3/16" x 3/4" stick for the stab trailing edge
Pin the parts in place over the plan as you
assemble them but be careful not to glue the
elevator to the stab D 7 Glue the other side sheeting in place Be
sure the stab is kept flat until the glue cures Trim
and sand the sheeting flush with the leading and
trailing edges of the framework NOTE: It is
essential to get a strong and complete bond
between the stab sheeting and the stab
framework, especially in the center, therefore,
we recommend using 30 minute epoxy when you
apply the last piece of sheeting Spread the epoxy
evenly but sparingly on the structure, to avoid
excess weight
D 3 Cut the stab and elevator "ribs" from the
3/16" x 1/4" x 24" balsa sticks (SKY6S04) Glue
these in place with CA.
D 4 Use a sanding block with medium (150) grit
sandpaper to sand the edges and both sides of
the stab and elevator smooth Carefully draw a
centerline all around the edges of the stab and
elevator This will make it easier to maintain
symmetry when sanding later.
D 8 Carve and sand the leading edge to a nice
rounded shape as shown on the plans, but keep
the trailing edge and the tips square
D 5 Glue two 1/16" x 3" x 24" balsa sheets
(SKY6S06) together (edge to edge) to form one
piece of stab sheeting Sand or trim the edge of
the sheets before gluing to obtain a good joint
between the two, without any gaps After the glue
is cured, sand both sides of the sheeting with a
fine grit sanding block Make sheeting for both
sides of the stab.
D 9 Using a sanding block and coarse (80-grit)
sandpaper, sand both sides of the elevators to a
taper (see cross section on plans) The trailing
edge should end up approximately 3/32" wide
D 6 Thoroughly glue the sheeting to one side of
the stab Keep the stab flat while attaching the
sheeting After the sheeting is installed, trim it flush
with the edges of the stab.
D 10 Cut four 1/16" x 2-5/8" x 24" balsa sheets
(SKY6S08) in half to form eight 12" long pieces
Glue these 12 sheets together to form four 5-1/4"
wide sheets Cut one end of each sheet so it is
perpendicular to the long edges Sand both sides
of these sheets smooth.
