Hobbywing 30406902 – XRotor 3115 PRO 900kV 6S FPV Motor
Brushless FPV motor for 9–10 inch builds on 6S LiPo: 900 kV, up to 5.25 kg of thrust per motor and 127 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. This 900 kV version runs on 6S with 9–10 inch tri-blade propellers and gives up to 5.25 kg of thrust per motor.
