selecting servo arms. A believe there are 3 different spline drives in use. When
selecting aftermarket arms get the ones specifically intended for the servo
brand you are using such as 'JR' or 'Futaba'. Someone did a really nice
write-up on this some months back but I don't remember where I dead it.<o:p></o:p></span></font></span></p>

Control surface/linkage setup</span></font></p>

<p class=MsoNormal style='margin-left:.5in'><font size=3 color=black
face="Times New Roman"><span style='font-size:12.0pt;color:black'>I have a
question for the list about control surface/linkage setup. I
remember a K-factor article which mentioned making the servo arm is
as close to a perfect 90 degrees as possible at neutral. This is what
the little 1-2-3-4 on the stock plastic servo arms are for. You
simply rotate the arm until 90 degrees is achieved. However, with
aftermarket heavy duty plastic or metal arms, is there any other solution other
than sub-trim? I am concerned about the “stock” arms deflection under
load and like to use the aftermarket products, but on some servos on my
airplane, this leads to a lot of sub-trim, which is also
not preferable. Thoughts?</span></font><font size=2
