FINAL CONSTRUCTION

Build the Static Wing Struts

❏ ❏
1. Make a static wing strut by gluing two 3/16" x 3/16"
x 20" balsa sticks to one 3/16" x 3/8" x 20" basswood stick.
Cut the static wing strut to a length of 19-3/16".
❏ ❏
2. Use the detailed drawing of the static wing strut on
the wing plan as a template to cut the angles on the ends of
the strut.
❏ ❏
3. Use a #11 blade to bevel the opening in the 1/8" ply
wing strut support in the right wing half.
❏ ❏
4. Fit the top of the static strut into the wing strut support
in the right wing, then fit the bottom of the static strut into the
fuse as you bolt the wing into position. See if the static struts
are at correct length (they will most likely be slightly too long,
as this allows for trimming to the correct length). If necessary,
remove the wing and the strut. Trim the strut to the correct
length so it does not put any stress on the bottom fuse
sheeting or the wing. The strut is not functional and should
be slightly loose so it can "float" between the wing and fuse.
❏ ❏
5. Round the edges of the strut for a finished appearance.
❏
6. Once you have determined the correct length of the
static strut, build the other the same way. Note: The static
struts are not structural, but are intended to be in position
during flight for appearance.

Prepare the Model for Covering

❏
1. Disassemble the model and remove all components
that will interfere with final sanding and covering, such as
the engine, landing gear, pushrods, hinges, etc.
❏
2. Apply lightweight balsa filler to scratches, dents and
uneven glue joints that require filler. Before applying filler to
small dents and scratches, moisten the area with water,
causing the wood to swell.
❏
3. After the filler has dried, final-sand all parts of the
model with progressively finer grits of sandpaper, finishing
with 400-grit.
❏
4. Use compressed air, a dust brush, or a tack-cloth to
remove balsa dust from the model so the covering will
adhere well.
❏
5. If you haven't done so already, paint the cockpit
interiors with fuelproof paint. It is best to do this before
covering the model, as it is possible for paint to "bleed"
through the balsa sheeting and contact the back of the
covering. If this happens, some paints can cause blemishes
in the covering.
