Overview

The 3115 series is a high-torque, 12N14P long-range motor built for 10-inch FPV drones. It uses N52H-grade magnets and imported 5115 mm bearings for smooth, efficient output and long service life. A robust M5 shaft, 1919 mm (M3) mounting, and optimized magnetic circuit deliver strong thrust with low vibrationideal for 10-inch FPV drone cruising, cinematic rigs, and payload-capable builds on 6S.

Key Features

31 mm stator 15 mm height (12N14P) for high torque on 911 props; optimized for 10-inch FPV drone setups
N52H magnets, NSK/NMB 5115 mm bearings for durability and low noise
6S (25.2 V) operation; typical ESC: 6080 A depending on KV/prop
Standard FPV mounting: 1919 mm, 4M3; M5 prop shaft with lock-nut
Factory test chart indicates up to ~4.0 kg peak thrust on suitable 10 props (lab conditions)

Variants & Recommended Use

KV	Suggested Prop (6S)	Typical Role
400KV	1011 (bi/tri) with higher pitch	Efficient long-range cruising, low RPM cinematic X8
900KV	910 (bi/tri)	Balanced power/efficiency for most 10-inch FPV drone builds
1200KV	89 or light 10 (low pitch)	Responsive freestyle/short-range setups on 6S

Tip: Start with gentle timing and throttle curves; increase prop pitch/diameter cautiously while monitoring current and motor temperature.

Notes

Performance depends on propeller, ESC tune, and airflow. Always verify current draw on your specific 10-inch FPV drone before full-throttle flight.
