ELEVATORSELEVATORS

Parts that move up or down that cause the plane to Parts that move up or down that cause the plane to Pitch in the opposite direction. If the Elevator is up, Pitch in the opposite direction. If the Elevator is up, the nose of the plane will pitch down, and vice-the nose of the plane will pitch down, and vice-versa. versa.
