the cause of the two eleavator servo's not having equal throws is because the low line servos are not very accurate. You will tend to have quite a bit of difference in performance or movement between two like servo's. You're better off buying $30 digital servos and having a far superior working elevator.

PEOPLE, DO NOT FLY THIS PLANE FAST!!!!!!!! Look at the size of the ailerons and the counterbalanced elevators. This thing is a aerobatic gem, not a pattern ship. You will flutter the ailerons and strip servo's, just as the previous pics prove.
