Hwey RTW:

Yea I guess that flying wires would do the job. But it would look like doo-doo. Real plane did not have them. I have thought some about it. Hows about glassing it and painting the whole plane? The glass could be 1 1/2 oz or 2 ounce on the stab. And 1/2 or 3/4 oz on the rest.
I think that you could also very easily build a spar into the tail assembly. Maybe a 3/8 wide piece of balsa from tip to tip should do it.
Just a few more suggestions I thought up lately. Hope this helps
