style="FONT-SIZE: 10pt; 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></DIV>

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
