set it up as the manual states, that is what gives you the 90 degrees in relation to the servo and pushrod. I have attached photos of mine. This is at mid stick 5.5 degrees of pitch. I set my pitch curves to the manual on hovering from -2degrees pitch to +9 at full up. I am hovering around half stick with this curves. Here are the pictures hope this helps you out,and clears things up for you. The second pic is the throttle and collective at mid- stick. take care mike
