E-POWERRC X3115 900KV/1050KV/1200KV Brushless Motor 6S, 3745.3mm – for 810″ props, 10inch FPV Drone

Description

Overview

The E-POWERRC X3115 is a high-torque FPV multi-rotor motor built on a 3115 mm stator. It uses N52H magnets, 18-AWG 250 mm silicone leads, and precise dynamic balance (5 mg) for smooth, low-noise operation. Offered in 900KV, 1050KV, and 1200KV, it pairs with 810″ carbon props on 6S. The 900KV variant is especially suitable for 10inch FPV drone long-range builds, delivering strong thrust with good efficiency.

Key Features

• High-conductivity copper windings and N52H magnets for strong torque and durability

• Low noise, smooth throttle; dynamic balance 5 mg

• Anti-loosening prop nut and mounting screws included for secure operation

• Laser-engraved can; clean, serviceable structure

• All KVs support 6S LiPo

The load-test tables in the images provide example thrust/RPM/efficiency at 25 V for 104.5 (900KV), 94.7 (1050KV), and 84.5 (1200KV) props, with measured temperatures at full throttle.

Selection Guide

• 10inch FPV drone long-range / endurance: choose 900KV + 104.5 CF on 6S for the best efficiency and thrust margin.

• Balanced agility (9″ builds): select 1050KV + 9″ prop for quicker response.

• High-rpm small-prop performance (8″): select 1200KV + 8″ prop; ensure cooling and an ESC 90 A.
