GTSKYTENRC Tracker 3115 900KV Brushless Motor for 911 Inch Long-Range FPV Drone | 12N14P, M5 Shaft, 6S, 1919 mm

Overview

The GTSKYTENRC Tracker 3115 900KV is a high-torque, cinematic/long-range class motor built around a 3115 mm stator for 911 inch FPV quadcopters. A 7075-T6 bell, titanium-alloy hollow shaft (M5), 12N14P architecture, and N52H arc magnets deliver smooth control with excellent efficiency. It mounts on the standard 1919 mm (M3) pattern and ships ready to drop into long-range, cruiser, and payload builds.
