Electric Thruster
The heavy fiberglass thruster support shaft is indexed into a retractable steering motor, which allows our software to control the thrust angle. (With the later addition of a rudder autopilot interfaced via the hydraulic system, this will give the Microship extremely precise automatic steering capability.) The whole assembly is mounted in an aluminum bracket that allows the motor to be extended and deployed from the cockpit.
There's a fairly poor video frame-grab of the thruster itself here.
The real smarts behind this is the adaptive thruster control system, which both steers the motor and delivers a continually fine-tuned power level that exactly utilizes left-over solar power after the battery and other system loads are satasfied.
