Teran, Welcome to RCU (And all the crazies that hang out here )

Jon, actually, using a small amount of expo will make your controls MORE linear. Because, if you think about it, your servo is actually providing you with REVERSE expo.

How so?

Look at how the pushrod travels as the servo rotates in the illustration below.

This shows six, 10-degree rotations. You can see how the servo moves the pushrod MORE at the center of stick movement than it does at the end.

So a rotating servo wheel actually gives you the OPPOSITE of expo
