<DIV><FONT face=Arial size=2>Never have seen it before, but I guess the
main question I have concerns the potential for loss of effective torque
transmitted to the control surface. I see that they claim it's
better due to no losses. That would be true in the sense that you
don't lose that little bit in the linkage friction etc., but if you only
want, say, 25 degrees of surface throw each direction, it would appear
that you would have to limit the servo travel to 25 degrees as well.
If that's true, then you have less mechanical advantage for a given degree
of movement for the surface, since you would normally have a servo
traveling about doub! le that distance. The control surface speed
would be quicker, assuming the load is handled without any blowback or
slowdown of movement due to the effectively lower torque transmitted while
moving. Maybe I'm not seeing it right, but it looks like it might
not be such a good thing to use, unless you were already planning on
having something close to a 1:1 correspondence of degrees of servo arm
movement to degrees of surface travel.</FONT></DIV>
