Hobbywing 30406903 – XRotor 3120 PRO 700kV 8S FPV Motor
Brushless FPV motor for 9–11 inch builds on 8S LiPo: 700 kV, up to 7.32 kg of thrust per motor and 160 g including leads.
The XRotor PRO 3100 series is Hobbywing's premium range of 31-size FPV motors, built for cinematic aerial filming, heavy camera payloads and competition. Hand-wound windings with a high slot fill, N52SH arc magnets and 0.1 mm low-loss stator laminations give more thrust and higher efficiency, and a self-cooling bell keeps temperatures down under heavy load. The 3120 is the largest motor in the PRO 3100 series. This 700 kV version runs on 8S with 9–11 inch tri-blade propellers and gives up to 7.32 kg of thrust per motor – for the heaviest camera rigs.
