Product overview
The YAHREE 3110 is a brushless propulsion component for long-range FPV aircraft, payload drones and aerial photography platforms. Its 12N14P electromagnetic architecture supports smooth torque and low vibration. The motor measures 37.1+/-0.15 mm in diameter and 41+/-0.3 mm long, with a weight of 87.5+/-2 g, defining the component envelope for airframe integration. Both winding versions share recommendations for 4–6S LiPo batteries, a 6S/100A ESC and 8–10 inch propellers. The package contains one motor, mounting screws and accessories, with a propeller adapter offered optionally.
The 900 KV version has a continuous rating of 38 A/950 W at 25 V, while the 1250 KV version is rated at 50 A/1250 W under the same voltage condition. Their maximum ratings rise to 58 A/1450 W and 85 A/2125 W respectively, each limited to 10 seconds. Temperatures at maximum continuous current are 70°C and 83°C respectively. Magnets have a 150°C maximum operating temperature, with 120°C recommended as the maximum. Thrust depends on propeller, voltage and test conditions. OEM/ODM projects can specify custom KV, appearance and color.
