OoooKay!!
Have you used adhesive tape for the elevons.
I did on my one attempt with these little rockets and I had a very similar problem - mine would spin out everytime on a right turn, not left turn just right. And it was totally irrecoverable straight down!!
The only possible cause that we could find was the tape had lifted slightly on the right elevon. This meant that when the right turn was signalled, the servo was pulling the front edge of the elevon above its proper position as full up was applied.
Reading your last sentence as quoted I get the impression that either -
The only other possibility that I can think of is fairly unlikely. Is it possible that one side is twisting under full elevon? Errrmm if you give it full up the te of the wing goes down? I can see it happening but not with EPP and fg reinforced tape. Just a thought forya.
Oooohhh!! One other thing...
Are the elevons deeper (chordwise) at tip or centre? They seem to behave better with the taper from tip to centre rather than outward. It seems counterintuitive but it works.
And hey!!! What is wth that gap thingy at the back - is one elevon different to the other? Look at the photo - see how the te's don't seem to match? What is that? An optical illusion?
