Well, I would rather NOT think of us as a government think tank! I have a 
better opinion of the KRNet than that! ;-)

I just want to say that I've been following the comments that have been
made on this site for only a couple of weeks. This site reminds me so
much of a government think-tank. You good folks come up with some VERY,
VERY interesting questions and comments, like the one below made by
Ameet. If you think about it, this is where "cutting-edge technology"
starts - by interested, dedicated people, like yourselves asking
questions, making comments, trying new things, and coming up with new
solutions. I belong to quite a few aviation discussion groups, but this
one runs circles around the rest. I'm hyped! Keep up the fantastic work!

Load is not just a function of airspeed it also
depends on size of the control surface (among other
things) 200 mph of an small R/C plane is not the same
load on the control surface as 200mph for a full scale
airplane.

As I mentioned earlier, R/C gliders use "KEVLAR" for
this purpose. I don't know the theory behind it nor
the numbers to justify the fatigue life. But there
must be some logic to it and might be a good start for
someone to investigate such a hinge method.
