- Overview
- Technical specifications
The Scorpion A2 - 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 high temp enamel coated copper wire windings rated above 200C+, 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 A2-5017-250kv was designed specifically for acrobatic airplanes with 67-68 inch wingspan running on 12S Lipo, or other airframes requiring up to 3500w of power.
