Just out of curiosity, I notice that all of the Pitts aircraft have
flying and landing wires attached on only the main spars, and the Acro
Sport aircraft have them attached on both the main and rear spars.
From what I have seen, the wings on both aircraft aren't made much
differently, and I can't imagine the stresses ( wing twist ) being any
greater on the Acro Sport than the Pitts. Anyone know offhand why the
extra wires on the Acro Sport? thanks
