Another aircraft is the AeroVironment Helios, which was solar powered and flew with ten or fourteen electric motors. The torque of an electric motor can be controlled very rapidly and precisely, far faster than gas turbines.
To turn the aircraft in flight, yaw control is applied by applying differential power on the motors — speeding up the motors on one outer wing panel while slowing down motors on the other outer panel.
In fact, in this flying wing design, differential thrust also provides pitch control:
A major test during the initial flight series was the evaluation of differential motor power as a means of pitch control. During normal cruise the outer wing panels of Helios are arched upward and give the aircraft the shape of a shallow crescent when viewed from the front or rear. This configuration places the motors on the outer wing panels higher than the motors on the center panels. Speeding up the outer-panel motors caused the aircraft to pitch down and begin a descent. Conversely, applying additional power to the motors in the center panels caused Helios to pitch up and begin climbing.
Had the aircraft not crashed, the eventual plan was to remove the elevators, the only control surface, and fly completely by differential thrust.
