Product overview
The HOBBYWING Xrotor 2306 Race Pro serves as a propulsion motor for professional-class FPV freestyle and speed racing. Its construction combines CNC-machined 7075 aluminum, a hollow titanium-alloy shaft, Japanese EZO bearings and N54 NdFeB magnets. The stator uses 0.1mm silicon steel laminations, with an optimized design intended to reduce iron and copper losses. At the propeller interface, the holder increases friction against the front endbell to resist slipping under impact. The front endbell and shaft also incorporate changes aimed at improving radial and axial strength.
Integration dimensions are shared across the four KV configurations: a 27.9mm rotor diameter, 17.5mm body length, 5mm shaft diameter and 30.7mm overall shaft length. Each motor weighs 27.5g excluding cable and has a 20AWG/150mm wire specification. Electrical selection depends on the variant: 1600KV uses 6S LiPo, 1750KV uses 5~6S, 2400KV uses 4~5S and 2700KV uses 4S. ESC specifications range from 30~40A to 40~50A. Recommended propellers are 5~6Inch for the first three variants and 5Inch for 2700KV; maximum continuous current and power ratings carry a 30s qualification.
