<DIV>Matt, my reply wasn't intended for you, it was for Ted's benefit. You're
answer stated that to top hinge would be OK if he had the horn located correctly
to produce symmetrical throw top and bottom. For me this left the impression
that it might be *necessary* to find the exact symmetrical location. My "color
commentary" comment was simply bring up the point for Ted that it's not
necessary to find the *exact* point because he can always adjust the end points
using his radio. It wasn't my intention to suggest that either you or Ted didn't
know how to do this. </DIV>
<DIV> </DIV>
<DIV>BTW, I agree that it's better to have a sound mechanical setup. You don't
want to have your servo moving only 50% of it's entire range or 110% in one
direction and only 55% in the other. However, I don't understand the
hang-up some people have about not wanting to use the throw adjustment our
radios provide beyond a "few percent" (by the way, what is a few percent).
What's the big deal? Do you really think you can tell the difference if a 15% up
and down deflection on your ailerons requires the servo to travel 110% up and
only 85% down? You move the stick and the ailerons move the exact point you want
within fractions of a millimeter. With the resolution we have I just don't
understand how this makes any difference, *especially* when it comes to the
elevator. It's common place to have different up/down deflections on the
elevator anyways. As long as it's not a gross error that would noticeably effect
the resolution or torque of the servo, what's the big deal if the adjustments
are done mechanically vs. electronically?</DIV>
<DIV> </DIV>
<DIV>If there are really good reasons I'm definitely open to learning these.

<DIV>NO!!! REALLY???? GEEZ I DIDN'T KNOW THAT (jus' kiddin' Keith, and pokin'
a little fun)</DIV>
<DIV> </DIV>
<DIV>With the kind of geewhiz programmability available nowadays, too many of
us have become a little complacent and use the electronic fixes as cure alls.
I am old school and prefer to make the mechanical set-up as sound as possible
first, then use the radio to trim the mechanical set-up if needed. If it
needs more than a few percent electronic fixing, I usually re-do the
mechanical set-up in my pattern models. I do not subscribe to electronic fixes
for everything! (Sport planes are another matter)</DIV>
<DIV> </DIV>
<DIV>Having to electronically fix knife edge flight for example, just frosts
me, particularly when a kit costs over $1000 in some cases. </DIV>

<DIV>Assuming the use of a computer radio, it's easy to program the throws
in the radio to make sure they're symmetrical.</DIV>

<DIV>Ted, in my experience it makes no difference as long as the horn is
located correctly to produce symmetrical throw top and bottom. More
difficult to do that with a top hinged surface than a center hinged
surface, so be aware of this pitfall. Yet, the top hinged surface is much
easier to seal than a center hinged surface, so there are always
compromises in everything we do. </DIV>
<DIV> </DIV>
<DIV>Personally, I always center hinge my surfaces. </DIV>
