SCORPION A-4220-540KV

Scorpion A-Series motors are designed to be the optimal and first motor choice for your freestyle or UAV aircraft.
We have achieved incredible performance through incredible efficiency. By optimizing the magnets in the rotor and using the best quality 0.2mm thick silicon steel stator laminations and 2 x single strand enameled copper wire windings rated at over 200 ° C, the power and efficiency results are unlike anything we have seen before! Combined with a rugged design that has been extensively tested for durability and reliability by our world class team pilots, we believe this motor checks and exceeds all measurable categories!
