Scorpion A-4225-500kv V2

Features

The Scorpion A-Series motors are designed to be the optimal and premium choice for your freestyle or UAV aircraft. We have achieved incredible performance through incredible efficiency. By optimizing the magnets in the rotor and using high quality 0.2mm thick silicon steel stator laminations and single strand, enamel insulated copper wire windings rated at over 250°C+, the power and efficiency ratings are better than anything we've seen before! Combined with a robust design that has been extensively tested for durability and reliability by our world-class pilots, we believe this motor meets and exceeds all measurable categories!
The A-4225-500kv is specifically designed for aircraft requiring a 90E / 20cc-25cc equivalent internal combustion engine with 6s LIPO, or for other airframes requiring up to 3108W of power.
