To mount the stabilizer I had to remove the upper keel.
To prevent the fuselage from distorting I added two
diagonal stringers inside the fuse, at the bottom-rear.
This guarantees that the incidence of the stabilizer
and the downthrust will not change in time.

I made the prop blades for the "flying prop" as
shown on the plan. It is paddle style, using sheet balsa on
tooth pick spars. The tooth picks fit into a plastic tube
so the pitch can be adjusted, and pitch is oriented so that
I can use my winder without having to wind backwards.

I think the flying prop was not meant to be used with
a spinner, which is only shown on the static display prop.
But I think it deserves a spinner in flight because it
is an important characteristic part of this plane. Blue
foam was used here to save weight. Inside the spinner
I made a ramp style freewheel mechanism, as shown on the
left. In Dutch, “ramp” means disaster... I
hope this is not an omen!

The prop and tail block weigh about 1 gram.
I made a solid balsa nose cone for vacuum forming a the
glazed nose section. Luckily I was able to use the cockpit
plug from my pistachio Baxter Mustang to make the twin
cockpits. Wheels were made from black depron, on which
I glued printed wheel rims.

I covered the wings and front of the fuse with black esaki.
The rear of the fuse and tail surfaces were covered with condensor
paper to minimize weight.

|
I sprayed the covered parts using a can of silver acrylic car
rim spray. After spraying I put on all panel lines as indicated
in a 3-view. |
