<DIV>Let's not forget the flying stabs on a lot of jets. I believe Bob had
designed some for his kits and those airplanes have a higher flight velocity

<DIV>It has been tried before, way back in the 70s as I recall. I think Bob
Violet might have sold some hardware to do it. I know he designed a
pattern plane that was featured in one of the magazines back then that had a
flying stab. I know the glider guys use full flying stabs a lot, but for drag
reduction mainly. Not sure why it would not work, but I suspect you would not
get the same "feel" as you would with a conventional stab/elevator.</DIV>
<DIV> </DIV>
<DIV>With a conventional setup, you are able to play with the camber of the
horizontal surfaces, which can be used to trim the downlines for hands
off.</DIV>
<DIV> </DIV>
<DIV>Someone correct me if I am wrong, but when wing tubes became prevalent, I
believe someone (I think Chip Hyde) experiemented with wings that rotated on
the tubes instead of using ailerons. That did not work well, from what I
understand.</DIV>

<DIV>Now that a lot of 2M planes are going to removeable stabs, it seems a
short step to full flying stabs. Is there any advantage to this type of
stab? Seems like it almost would be easier set up, you wouldn't need to
worry about wing to stab incidence.</DIV></BLOCKQUOTE></DIV>
