KAVAN PRO motors are high-performance brushless fourteen-pole electric motors with a rotating casing ("outrunner") with excellent electrical properties, sophisticated construction and top-quality manufacturing. Shafts made of hardened steel and high-quality bearings ensure a long service life, quality materials used for the manufacture of the stator and rotor also guarantee excellent performance parameters with high efficiency. They are low-speed, high-torque engines that handle large-diameter propellers and climbs without the need for a gearbox.
