SunnySky

SunnySky develops electric-propulsion components around the voltage, thrust, efficiency and thermal requirements of a specific aircraft. Its range includes outrunner brushless motors for multirotors, fixed-wing aircraft and helicopters, together with electronic speed controllers and rigid or folding propellers. The M industrial-drone series and EOLO products extend the catalogue into larger UAVs that operate at higher voltage and carry heavier payloads.

Aircraft builders select a motor winding, ESC current rating and propeller diameter as a matched power system, coupling each component to the aircraft's electrical and aerodynamic requirements. SunnySky characterises combinations by voltage, throttle, current, thrust, efficiency and temperature, allowing an integrator to compare them against the airframe's payload and endurance target. SunnySky supplies standard propulsion sets and individual components to manufacturers, integrators and model-aircraft users, with carbon-composite propellers available for applications requiring lower mass and stiffness at larger diameters.
