Description
The Scorpion A – Series line of motors was designed to be the most optimal and premier choice of motor for your freestyle or UAV airplane. We have achieved incredible performance through incredible efficiency. By optimizing the magnets in the rotor, and using the best quality 0.2mm thickness silicon steel stator sheets, and single strand enamel coated copper wire windings rated above 250C+, the performance and efficiency results are unlike anything we have seen before! Combined with a robust design which has been tested extensively by our world class team pilots for longevity and reliability, we feel this motor checks and exceeds all measurable categories!
The A-4225-500kv was designed specifically for airplanes requiring a 90E / 20cc-25cc equivalent gas engine on 6s LIPO, or other airframes requiring up to 3108w of power.
