style='font-size:10.0pt;font-family:Arial'>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.</span></font><o:p></o:p></p>

style='font-size:12.0pt'>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<o:p></o:p></span></font></p>
