I'm using two servos because it's a split aileron. It can deploy the upper and lower surfaces up and down together as an aileron, deploy only the upper surface upwards as a spoiler, or deploy the upper surface upwards and the lower surface downwards as an air-brake. It can deploy an air-brake on the left wing to yaw left and vice-versa. When this is controlled by a flight computer, there is no need for a vertical stabiliser.
