Can you describe the physical configuration of
the vertical fin vis-a-vis the empennage? Is
the vertical fin detachable?

Hi Bob,
Thank you for responding.
The vertical fin is integral with the fuselage, which comes as two halves bonded together along the vertical plane of symmetry, like a plastic model.
The whole airframe is carbon, except the vertical fin which is made of glass.
Hope the included picture taken some days ago is getting through.

The antenna istself will be enclosed in the vertical fin.
We'll have some access by crawling in the fuselage up to "some distance" from the fin base.
Also there will be a removable aft tail-cone to give some access to the control linkage in the tail and -hopefully- to the antenna connection.
Depending on the details, we might be able to make the antenna removable by sliding it into a plastic tube installed in the tail ?
Thanks for your advice,

If there is access to the inside of the tail cone, then put the ground plane inside. It can either be a large sheet of thin metal, or else radials made from wire or metallic tape. The fore and aft radials can be horizontal. The left and right radials can follow the curved tail skin.

I noticed that the inside of the fuselage is black. Is it carbon fiber or is that just a layer of black poly?
