A high quality ESC for a great price. The SpeedyBee BLS 4in1 ESC is an excellent choice for a wide range of builds, from power hungry freestyle drones, to long range cruisers. Each ESC motor output can withstand a true continuous current of 55A and 70A peak for 5 seconds. Built with the robust BB21 MCU, this ESC runs BLHeli_S firmware and operates under the Dshot 300/600 protocol. It features Japan made TDK filtering SMT capacitors and the ESC is built with a TVS protective diode to absorb the voltage spike when you plug in the battery, or during crashes that block your props. SpeedyBee also provide a humongous 1000uF low ESR capacitor, ensuring clean data from the gyro to the FC. Lastly, the ESC has large motor pads for easy soldering.
