It is usually better to pull up elevator, rather than push it. This way the push rod won't flex when pulling out of a dive or loop, etc. However, this requires having the horn on the top of the surface.

Set all of your EPA's to 100% travel. Then, make sure your push rods are connected to the INNERMOST holes on your servo arms/wheels and connected to the OUTERMOST holes on your control horns.

This does two very important things. One, it gives you maximum resolution so that your surfaces travel smoothly, precisely and proportionally to your tx stick movement. When you move your tx stick 1/4 of the way, the control surface should also move 1/4 of it's total travel, and so on. Second, it allows you to use more of the servos' torque. And, third, it will decrease control surface travel mechanically, which is a thousand times better than using EPA to decrease travel. You can use EPA to make fine adjustments to your travel, but the closer it's set to 100% the smoother your plane will fly.

Nine times out of ten when a pilot has a twitchy, sensitive new plane it is because they have the push rods hooked up wrong. By hooking them up as I described you will use all or most of your servos' travel which will always give you the smoothest and most precise control of your plane. It makes a night and day difference in how your plane will fly.
