Product overview
The HOBBYWING XRotor 3110 PRO provides motor propulsion for professional aerial cinematography and racing, with 900KV and 1250KV variants. Its outer-rotor support uses densely arranged cooling teeth to carry heat away from the windings during flight. The construction combines hand-wound, high slot-fill windings, 0.1mm low iron-loss silicon steel laminations, a titanium-alloy main shaft and N52SH arc magnets. Both versions have 12 slots, 14 poles and 1150ZZ bearings. Their Class C enamelled winding wire resists 220°C, and the winding insulation specification includes a 500V AC dielectric withstand test.
Installation requires a Φ37.2 × H29.2mm motor envelope and a Φ19mm mounting pattern with four M3 holes. The output shaft is Φ5mm in diameter and 17mm long. Each motor weighs 100g including 250mm leads, using 18AWG wire for 900KV and 16AWG for 1250KV. Recommended integration pairs either version with a 6S LiPo battery and XRotor FPV G2 65A 4in1 ESC. The 900KV propeller choices are HQ8X4.5X3, HQ9x4x3 and HQ9x5x3; the 1250KV choices are HQ7X4X3 and HQ8x4x3.
The 900KV version has a rated output of 280W and maximum thrust of 3.87kg, while the 1250KV version has a rated output of 380W and maximum thrust of 4.25kg. Maximum current is restricted to 70.4A for 8s on 900KV and 82A for 16s on 1250KV, in a non-enclosed environment at ambient temperature ≤25°C. Maximum power also carries explicit duration limits: 1686W for 8s and 1969W for 16s, respectively. At 24V, no-load current is 1.78A for 900KV and 3.55A for 1250KV.
