I know that the Spitfire wings have wash out I was told by an owner of a Spitfire at my Club, but in fact himself did not know a clear idea of the washout, I will build a P-47 and want to know if the wings have washout, by now I have understood that this washout is a twist of the wings, and is good to maintain the plane flying at different speeds, because the wing keep flying on some part when other part of the wing has stalled (am I right?). I also have understood that is measurable (Thanks Darock). I was told by a friend on my club that he lost his first spitfire by a wrong design from Top Flite, because (He says) that "the horizontal stabilizer has a wrong incidence because the main wings have washout" then the plane rolled. That is why I wanted to know if the washout had any thing to do with the tail section. Wel I think that this a good issue for many modelists.
