Overview

The GEPRC EM3110 900KV is a new EM-series long-range motor built for 6S platforms and 810 inch FPV drones. It uses a high-strength M5 steel shaft, 12N14P high-torque magnetic circuit with N52H magnets, and a rigid 1919 mm mounting base. Low-resistance single-strand copper windings and NSK/NMB bearings deliver smooth efficiency for long-range cruising while providing enough punch for freestyle on 8, 9, or 10-inch FPV drones.
