Hobbywing's SKYWALKER motors are high-performance, commutatorless ("brushless") fourteen-pole rotary ("outrunner") electric motors with excellent electrical characteristics, sophisticated design and superior manufacturing quality. Shafts made of hardened steel and high-quality bearings ensure a long service life, and the high-quality materials used for the stator and rotor also guarantee excellent performance at high efficiency. These are low-speed, high-torque motors that handle large-diameter propellers and operate without the need for gears.
