You can see it in motion here. https://www.youtube.com/watch?v=mrJgoQz5wSU https://www.youtube.com/watch?v=mrJgoQz5wSU The major challenge for this aircraft seems to be control, accomplished by some clever programming of the flight controllers. None of the planes have a rudder, so yaw control is accomplished solely by differential throttle. They also have no ailerons - each plane uses its elevators, with its own response direction and magnitude, to control the overall aircraft's roll.
