Dave, I ran 2024. Rex Taylor wanted to check the system out. We went
flying and at 140 mph indicated Rex told me to look back and see if I could
see the aileron come up when he bumped the stick. Wellllll, he more than
bumped the stick, he slamed it to full deflection and back in an instant. I
told him I didn't see the aileron. He said that he was afraid of that. The
aluminum had touque wind up. I installed 3/4" .035 wall 4130. We did the
same test and this time I did see the aileron come to the top. Needless to
say I have got a new perspective on the DF control system and some of the
things that you will never think of when making changes.
Install what ever you like, my choice if I were to do it again would be
4130.
