SureFly eight-rotor helicopter makes first flight
The SureFly has eight props, two on each of four arms. All are driven by individual electric motors. It has a petrol piston engine which drives two generators for the electrical power, plus two 7.5kWh lithium battery packs for an emergency landing should the generator fail.
