Wm,

That’s why I like to draw it out on good old paper and vellum! It also lets you figure out the differential available by changing the angle of the control arm on the ailerons. The differential created by rising or lowering the servo position in the wing can also be analyzed. Years ago Kavan made servo output arm disks without holes that were marked in degrees and you could drill your own holes. Once you figure the differential for one aileron then you just repeat the linkage setup for the other side.
