Update Time!!
I did some tests for the full flying stab, with a BBQ skewer. There are a couple things that show a red flag, (1) If you hold hot glue sticks you can see that it's "rubbery" and when I glued down the BBQ skewer there was some flex originating from the glue joint (2) After I found out that hot glue wasn't going to work I tried it with some white gorilla glue to see if there would still be flex from the glue joint, so I used a short ~2 inch long piece of BBQ and adding a bit of torsional force to it, the skewer itself frayed!!
So I'm not going to do a full flying stab, because I want to keep this a relatively simple build, and using a simple setup for the full flying stab could lead to reliability issues, on a very important part of the plane. So I'm going to do a regular elevator instead.
On the bright side of things I got a new way for making a FB turtledeck that looks really nice, and the design is coming along very nicely. Any updates from you Damo?
