Most powered model-aircraft, including electric, internal-combustion, and rubber-band powered models, generate thrust by spinning an airscrew. The propeller is the most commonly used device. Propellers generate thrust due to lift generated by the wing-like sections of the blades, which forces air backward.
Utah-based Electric Power Systems provides the 92-kWh energy storage including battery modules, management and distribution. The 138 kn (256 km/h) cruise aircraft is projected to have hourly operating costs one-sixth of a piston-powered Cessna 172. [15] The Safran motor announced in November 2020 will be from the ENGINeUS 100 line. [23]

On April 29, 1979, the Mauro Solar Riser became the first person-carrying, solar-powered aircraft to fly, with photovoltaic cells delivering 350 W (0.47 hp) at 30 volts and charging a small battery, which powered the motor. Following a 1.5-hour charge, the battery could power the aircraft for 3 to 5 minutes to reach a gliding altitude. [57]
It is powered by the sun during the day, before switching to battery power during the night and can potentially stay airborne for 12 months. Featuring long-life battery technology, ultra-lightweight solar cells, a 35-metre (115 ft) wingspan and a weight of 150 kilograms (330 lb), the aircraft is designed to operate in the stratosphere. [2]
