DarwinFPV 3115 900KV Brushless Motor for 910 Inch Long-Range / CineLifter FPV (6S, up to 4.5 kg thrust)

Description

Overview

The DarwinFPV 3115 is a 900KV heavy-lift motor purpose-built for 910 inch long-range and CineLifter FPV drones. Running on 6S (24 V), it delivers up to 4.5 kg of thrust with a GEMFAN 1050 prop, while maintaining smooth response and high efficiency. A lightweight 7075 aluminum bell, 5 mm stainless-steel shaft, 12N14P architecture, and N52H arc magnets ensure strong torque and stable footage on payload-bearing builds such as CineLifter X8 platforms.

Key Features

• Heavy-lift performance: max thrust up to 4,525 g (24 V, 105 prop).

• Precision & durability: 7075 aluminum bell, 5115 mm bearings (Japan import), stainless-steel shaft.

• Efficient magnetic circuit: N52H arc magnets with tight air-gap for lower current at the same thrust.

• Long-range ready: optimized for 910 inch props; smooth, quiet running for cinematic flights.

• Easy build: standard 1919 mm (M3) mounting, 18AWG 220 mm leads.
