GTSKYTENRC Tracker 3115 900KV Brushless Motor for 9–11 Inch Long-Range FPV Drone | 12N14P, M5 Shaft, 6S, 19×19 mm

Overview

The GTSKYTENRC Tracker 3115 900KV is a high-torque, cinematic/long-range class motor built around a 31×15 mm stator for 9–11 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 19×19 mm (M3) pattern and ships ready to drop into long-range, cruiser, and payload builds.

Key Features
