The Hobbywing XRotor 2405 series of FPV Racing Motors feature a handful of great design features that are packed together that offer nothing but incredible performance, and excellent reliability. Featuring high strength CNC machined aluminum allow frame that incorporates a cross beam structure, & high previsision hollow alloy steel shaft, crash resistance and overall motor durability is a critical design choice. Offering an extra wide but short stator (24mm wide, 5mm height), the disc type structure provides a lower center of gravity compared to other motors, which translates to improved response while in flight. A single piece eight bladed centrifugal fan cools the motor during operation.
