Flying wings have no tails yet a tail is considered a crucial component of an aeroplane, so how do they work. A conventional straight wing would in fact be unstable if it had no tail to counteract its inherit upwards rotation, that's why planes have a tail wich force the wing to tilt back to level. But flying wings use two other methods to counteract the wings tilt, firstly the wings are tilted backwards to change the centre of gravity and make it more stable. Also, the wing has something called reflex at the back end of the wing which acts as a tail and can stabilise the wing. The parts of the wing that acts as reflex are also the control surface of the aeroplane, they are rotated up or down to control the aircraft. Rotating both in the same direction would cause the plane to pitch up or down and rotating them in opposite directions would rotate the plane on the roll axis. A combination of both of these controls is all that is required to pilot a flying wing.
