Product Description (Detailed):
Elevate your drone's performance with a high-efficiency 30A ESC speed controller, specifically designed for seamless integration with brushless motors. Our SimonK Brushless ESC for Drone is renowned for its fast throttle response and exceptional stability, making it a preferred choice for DIY drone builders and FPV enthusiasts. This Electronic Speed Controller (ESC) handles a continuous current of 30 Amps (A), with burst capabilities typically up to 40A for short durations, ensuring ample power delivery to your BLDC motors. It typically supports 2-4S LiPo batteries (7.4V to 14.8V), providing broad compatibility for various drone setups. Many 30A SimonK ESCs come with an integrated 5V/2A BEC (Battery Elimination Circuit), which conveniently supplies regulated power to your flight controller and receiver, simplifying your wiring and reducing overall weight by eliminating the need for a separate battery for your electronics. The pre-loaded SimonK firmware is optimized for multirotor applications, offering precise motor control and quicker reactions to flight controller commands, crucial for agile maneuvers and stable hovering. Features often include programmable settings for throttle range, timing mode, and low-voltage cutoff protection, ensuring both performance and safety for your aerial platform. This robust drone motor controller is ideal for quadcopters, hexacopters, and various RC aircraft, providing reliable and efficient power management.
The 30A SimonK ESC is a high-speed Electronic Speed Controller designed specifically for use in multirotor drones and RC aircraft. It is pre-installed with the SimonK firmware, known for its super-fast refresh rate, minimal latency, and excellent linearity, making it perfect for aerial applications requiring stable and responsive motor control.
This ESC supports up to 4S LiPo batteries and is compatible with popular brushless motors like A2212, making it a top choice for hobbyists, FPV racers, and DIY drone builders. The built-in BEC supplies 5V power to flight controllers like KK2.1.5, APM, Pixhawk, Naza, etc.
