Product overview
The YAHREE 4215 from Yahree Aeropower Tech Co., Ltd. is a large-format brushless propulsion motor for long-range and heavy-lift FPV applications. Its 12N14P slot/pole configuration comes in 380, 460, 480, 520 and 680 KV versions. The motor measures 49+/-0.15 mm in diameter and 65+/-0.5 mm in length, with a weight of 262+/-10 g. These dimensions and mass define its physical integration requirements. Custom KV, appearance and color options are available for OEM/ODM projects.
Battery, ESC and propeller recommendations depend on the selected version. The 380 KV motor recommends 10-12S LiPo cells, a 10-12S/100A ESC and a 12-inch propeller; the 460 KV motor recommends 8S, an 8S/100A ESC and a 13-inch propeller. Their maximum current/power ratings are 78 A / 3463 W at 44.4 V and 80 A / 2688 W at 33.6 V, respectively, each limited to 15 seconds. Thrust varies with propeller, voltage and test conditions. Magnet operating temperature is limited to 150°C, with a recommended maximum of 120°C.
