The particular UAV in the article is a plane shaped like a seagull. I doubt speed was requirement. The fact is aircraft have gotten faster since the Wright brothers and airframes have also gotten much stronger. Ailerons with ailerons you gained high-speed maneuverability at the cost of low-speed.

Since then, engineers have been trying to find more elaborate ways of regaining lowspeed flight maneuverability by adding more control surfaces. Flaps, for example extend the wing to increase the chamber. It might not be warping in the traditional context but they have definitely warped the airflow to the same effect.
