Product overview
HOBBYWING presents the XRotor 2207.5 as a brushless propulsion motor for FPV drones, with its specification table naming the configurations XRotor 2207.5SL. The manufacturer positions the 1780KV option for smooth freestyle control and the 1980KV option for racing response. Procurement therefore concerns a motor component rather than a complete flight platform or an airframe kit. Both variants specify 6S LiPo operation, while their published current, power, resistance and propeller-dependent thrust figures differ.
The motor combines single-strand winding, arc-shaped magnets and 0.2mm stator laminations. Its propeller mount incorporates cooling features and anti-slip teeth, which HOBBYWING describes as supporting heat removal and propeller retention. For installation planning, both variants have a published diameter of 28mm, height of 19.9mm and weight of 38g including wire. The interface specifications list a 5mm shaft with M5 thread, 12mm shaft length and Φ16mm-4×M3 mounting arrangement. Wiring is specified as 20AWG with 150mm length; confirm these dimensions against the selected configuration.
Recommended combination: an XRotor FPV G2 65A 4in1 ESC and separate propeller selections for each KV option. Maximum thrust is tied to the named propeller, and maximum power carries a three-second qualification. Maximum current also specifies non-hermetic conditions and ambient temperature no higher than 25℃. These published limits require configuration-specific assessment. The wire description and specification table use different insulation-grade designations, so that detail also needs confirmation before procurement.
