Product overview
The YAHREE 2814 Brushless Motor for FPV Drone is a propulsion component intended for heavy-lift and long-range FPV builds. Its 12N14P slot/pole architecture comes in 850 KV and 1100 KV versions, each with a ±10% KV tolerance. Both versions measure 33.4±0.1 mm in diameter and 43.5±0.2 mm in length, with a weight of 89±2 g. Integration recommendations comprise a 4–6S LiPo battery, a 6S/100A ESC and an 8–10-inch propeller. OEM/ODM projects can specify custom KV, appearance and color.
Version selection changes the electrical requirements and operating limits. At 25.2 V, the 850 KV motor has a maximum continuous rating of 30 A/756 W, while the 1100 KV version is rated at 45 A/1134 W. Their respective maximum ratings rise to 50 A/1260 W and 70 A/1764 W for no more than 10 seconds. Temperatures at maximum continuous current are 90°C and 94°C respectively. The magnets have a 150°C operating maximum, with 120°C recommended as the maximum. Thrust depends on propeller, voltage and test conditions.
