<FONT size=3 face="Times New Roman">I have a question for the list about control surface/linkage setup.<SPAN> </SPAN>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.<SPAN> </SPAN>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?<SPAN> </SPAN>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.
