<DIV><FONT face=Arial size=2>For fear of impinging on Troy's notes....in
"laymen's terms" (that's ALL of us, BTW, Tim)....as much as possible, in all
cases, ALL the time, have control systems "square, straight,
perpendicular"....at neutral, a line drawn across the servo from the clevis to
the center of the shaft should be parallel to the hinge line of the control
surface. A line from the control surface takeoff point TO the servo
arm/clevis should be 90* to the hinge line, and straight to the servo arm.
The attachment points should always be "short on the servo end, longer on the
control side" to avoid flutter, and keep mechanical leverage on the side of the
servo. And the last item...the "holes" for clevises should be set so that
you get recommended maximum throws with the tx set to 100% or more travel, the
servo takeoff point as close to the shaft as it can be, with the control takeoff
point as far OUT from the hinge line as IT can be.</FONT></DIV>

<DIV><FONT face=Arial size=2>It can be explained a LOT more complicated than
this, and probably easier. This is just the way I think of
it.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> ail control setup</DIV>
<DIV><BR></DIV>I just received my Jan K-factor yesterday, great timing since I
am re-doing<BR>my ail control setup. I was one of the ones that have my
dual rates at 40%<BR>low and 50% high so I certainly found Troy's article
interesting. This will<BR>be my second year flying intermediate and I
sure have a lot to learn,<BR>especially when it comes to airplane setup not to
mention flying... but<BR>that's all part of the fun.<BR> <BR>Now to the
question, which way should I mount the servos, should the control<BR>arm face
the leading edge or the trailing edge? I had it set up with
the<BR>servos facing the trailing edge to make the linkage the shortest
possible<BR>but I am going to go from 2-56 music wire to c.f. rods and don't
know if the<BR>distance to small. I could flip the servos and have more
room but should I<BR>keep the linkages as short as possible or is it not as
important due to the<BR>stiffness of the c.f.<BR> <BR>I am also having a
hard time picturing what Troy was saying about the<BR>tangent line when it
comes to attaching to the servo, could someone explain<BR>it in lay mans
terms?<BR> <BR>Thanks,<BR>Tim Wortkoetter<BR></BLOCKQUOTE></BODY></HTML>
