Hello,

Are there any articles / diagrams / tutorials that go over how to set up control surfaces by indicating the reasoning behind what hole to use on the servo arm and the control arm? For example, to do xxxx, then use the innermost servo hole and the outermost hole on the control surface. I'm looking for an easy way to decide where to put the control rods on both the servo and horn to affect control throws.

Thanks!

There are no set rules really, it's a matter of physics.

If you use the outermost hole on the servo, and the innermost hole on the control horn, you will get the most amount of throw. You will also be putting the most strain on the servo due to the amount of leverage the control surface has over the servo.

If you reverse the setup, (Innermost on servo - outermost on surface) you will get the least amount of throw, but your servo will have the strongest torque.

I usually start both on the outermost holes (It's rare that I want LESS control) and adjust accordingly. (In on servo for less control - in on surface for more control)

That's exactly what I was looking for, thanks!
