I am just finishing up my four star 40. I was wondering how much degrees throw in the elevator I should have. I am getting 10o degrees both up and down. That seems low to me. If it is low how can I get more degrees throw in the elevator? Positioning of the horn or is it all Servo are length?

Thanks

For the 4 star, that should be enough.
You really don't need a lot.

But to add more when/if you decide to; move the clevis "in" on the control arm, then "out" on the servo arm if you still want more. Beyond that, you need longer servo arms.
