Futaba FUMC951HA 50A Brushless ESC for 2-6S LiPo with 5.5V/3A BEC  [FUMC951HA]

Product Overview

The Futaba FUMC951HA is a compact ESC designed for radio-controlled electric models that require a 50A continuous current controller for brushless motors. It supports 2–6S LiPo battery configurations and provides an integrated 5.5V/3A BEC to power receivers and onboard electronics, making it suitable for aircraft and other scale RC applications where a reliable onboard power supply and motor control are needed.

The unit's role is straightforward: manage brushless motor power delivery while offering regulated BEC output for receivers and servos. When integrating this ESC into a model, follow standard RC wiring practices such as secure solder joints or connectors, correct polarity to the battery and motor, and careful routing of motor and power wires to minimise interference with the receiver antenna.

During setup, consider ESC mounting location for airflow and heat dissipation, and keep motor and ESC grounds common where required by your system. Use the transmitter programmer or compatible programming card if you need to adjust throttle response, brake settings, or motor timing; these adjustments affect in-flight behaviour and should be tested in a controlled environment.

Choose this ESC when your electric model requires a mid-range 50A controller with built-in 5.5V/3A BEC and support for 2–6S LiPo packs; verify compatibility with your motor and power system before installation and perform range and ground checks after installation.
