I have been doing the same thing since I started flying; that's the way I was taught. Connect the surface to the servo, as close to center as you can get. Then adjust the end points in the radio to get the throw you want.

I didn't want to jump your thread but since you brought it up. Expo; I just don't get it. I flew one of my planes and used the rate switch to try expo. Same amount of throw on upper and lower, but one had around 50-60% of expo. I didn't see a difference in how the plane flew or landed.

Maybe I just have a sensitive touch. LOL

Seriousely, if someone can explain what it is you're suppose to see or feel when using expo that would be great for me.

Thanx

p.s. I did that lil experiment on my H9 CAP and a Paramount 52.
