This picture shows the Cloudster's
horizontal tail (stab and elevator) after the surfaces have been carved and
shaped to form the rounded leading edges and tapered trailing edges. Due
to concerns over the small gluing area of the elevator rib ends to the
trailing edge, 1/16" gussets were added to one side of the ribs for
additional support as shown below. This finishes up the horizontal tail
structure, which is now ready for covering.
A weight check was done on the
removable horizontal tail as shown below. You can see that the hinged
horizontal tail structure weights 16 grams (0.56 oz), without the control
The picture below shows the Cloudster's vertical tail (fin and rudder)
after the surfaces have been carved and shaped to form the rounded leading
edges and tapered trailing edges. A weight check was also done on the
removable vertical tail and the hinged vertical tail structure weights 5
grams (0.18 oz), without the control horn attached. Also notice
that 3/16" gussets were added to one side of three of the rudder ribs for
additional support. This finishes up the vertical tail structure, which is
now ready for covering.
This is a close up of the fin
leading edge fairing that interfaces with the stabs leading edge.
This is a close up of the of the
rudder's cut out for the elevator's continuous spar pass through. Notice
that a radius has been provided around the rudder's cut out opening to
eliminate combination surface deflections such as full right rudder and full
This side view close up of the
tail assembly showing how the elevator's continuous spar passes through the
rudder cut out.
This is another rear view close
up of the tail assembly showing the elevator's continuous spar passes
through the rudder cut out. Notice that the bottom of the rudder has not
been trimmed off even with the bottom of the fuselage yet. This will not
be done until the fuselage's bottom bulkheads and stringers are glued in
As you may recall from Report No.
5, the fuselage primary structure weighed 18 grams (0.63 oz).
After building on the stab
mounting platform on the rear of the fuselage, the fuselage weight has
increased up to 20 grams (0.71 oz) as shown below. Therefore, the stab
mounting platform only resulted in a 2 gram increase.
The completed tail assembly was
mounted to the fuselage with the four 2-56 cap screws and weighed as shown
below. The weight has now increased to 46 grams (1.62 oz). Notice in the
picture that this weight includes the two control horns and four 2-56 cap
screws to secure the control horns to the control surfaces.
This past week I have been
working using a pair of +2.75 reading glasses that I bought at Walgreen's
for under ten bucks at Jim Lollar's recommendation. Since I broke my
prescription glasses, I had to have something to provide close up vision
with my single focus lens implants for distance. They took a little getting
use to, but I am getting by pretty well. Hopefully my prescription glass
repair will be ready Monday....................Tandy
