Full servo travel over half of the rudder stick?

Is there a way to get set up my rudder stick to make a servo travel the full range while just moving the stick half way?

Create a curve and then assign that to the channel

I'm sorry but I don't know what that means. Is that done in the mixer for the rudder channel?

Try it with a 5-point curve the way you need it. The values in the example are:

Point 1: -100
Point 2: -100
Point 3: 0
Point 4: 100
Point 5: 100

Attached are two pictures for overview.

Thank you, that helped . I guess my issue is getting my servo to move the full 180 deg. verses only 90 deg.

What in either direction of the stick or only in one direction ?

The servo only moves 45 deg each way.

Is the servo specified for 180° movement?

Btw: It would be nice to get some more information about what you have in mind. Describe the application with your words to make it clearer and easier to understand.
