Power 90 Brushless Outrunner Motor 325KV (EFLM4090A)

The Power 90 Brushless Outrunner Motor is a high-torque external-rotor powerplant designed to deliver the performance of a 90-size glow engine for sport and scale airplanes. It suits aircraft weighing about 8 to 13 pounds and can drive 3D airplanes up to around 10 pounds, providing up to 1800 watts of clean, quiet power for spirited flight.

Built with an external-rotor design for improved cooling, it features ball bearings and a hardened 6mm steel shaft for durability. Mounting hardware is included for straightforward installation, and the motor supports 6S–8S LiPo or 18–26 NiMH/Ni-Cd batteries, driving 16x8 to 18x8 propellers when paired with an 85A high-voltage ESC.
