SUMMUSKY 40A 2–6S Brushless Motor ESC for RC Plane & Fixed-Wing Airplane

Designed exclusively for RC fixed-wing airplanes, the SUMMUSKY 12A–100A Brushless Electronic Speed Controller series delivers the reliability, smooth control, and ease of use trusted by RC pilots worldwide. Whether you are building your first trainer aircraft or upgrading to a higher-power sport plane, this ESC provides precise throttle response and stable power for confident, controlled flights.

NOTE:This RC Brushless ESC series is designed for RC airplanes Middle class electric powered gliders, 3D/sports airplanes, F3As and Fixed wing UAVs. Not suitable for cars, boats, helicopters, or multirotor drones.

KEY FEATURES:

Advanced control algorithms ensure excellent throttle linearity for predictable acceleration and stable flight performance

Built-in switch-mode BEC delivers stable power to receivers and servos, reducing wiring complexity and eliminating the need for an external BEC.

Compatible with most sensorless brushless motors, including high-RPM motors commonly used in RC airplanes.

Utilizes advanced MOSFET technology to reduce heat generation, improve efficiency, and enhance long-term reliability.

Includes power-on protection, over-temperature protection, low-voltage cutoff, and signal-loss protection to help protect your ESC, motor, and aircraft.
