HOBBYWING XRotor FPV 3115 900KV Motor

The HOBBYWING XRotor FPV 3115 900KV is a powerhouse motor specifically engineered for 9-10 inch Long Range and Cinelifter FPV drones. Built to carry heavy cinema cameras like the RED Komodo or BMPCC, this motor delivers the torque and reliability required for professional-grade aerial filming.

Designed for heavy-lift applications, the 3115 features a 7075 aluminum unibody bell and a TC4 titanium shaft for maximum structural integrity. The motor utilizes a unique "tooth groove" anti-slip propeller mount, ensuring your props stay locked in place even under the immense torque generated during aggressive maneuvers. Internally, it is equipped with N52H arc magnets and 220°C heat-resistant windings, providing a 5% increase in efficiency and up to 50% longer runtime under heavy load compared to standard motors in its class.

With a 900KV rating, this motor is optimized for 4-6S LiPo setups spinning large 9-inch or 10-inch propellers. Whether you are mountain surfing with a long-range rig or chasing cars with a heavy lifter, the XRotor 3115 offers the smooth, locked-in feel and raw power that Hobbywing is famous for.
