That is what it seems to me. After hooking up servos. Make sure servo is centered with radio and plane on. It will deviate if you center without them on. You can move the servo arm to adjust this making it off center just a bit. But evens up and down. You can adjust travel movement with your radio if your radio is cabable. Get your manuel for TX and do what it says to adjust servo movement. You can get it done. IF you need and are a member of a club some of your club members will know how to make it right. And can probabaly do it at the field. Good luck.
