This bidirectional brushless ESC is designed for use in RC boats, underwater thrusters, and RC cars. Its true bidirectional 1:1 power output and quick reverse response make it ideal for any RC application requiring forward and reverse motor control.\u003c\/p\u003e\n\u003ch4\u003eQ: Do I need to calibrate the ESC before use?\u003c\/h4\u003e\n\u003cp\u003eA: No calibration is required. This ESC is plug-and-play — simply connect it to your motor, receiver, and LiPo battery pack (2S–4S) and you're ready to run right away.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between the 30A and 40A versions?\u003c\/h4\u003e\n\u003cp\u003eA: The 30A version supports a continuous current of 30A with a 10-second burst of 35A and measures 72 × 27 × 10 mm. The 40A version handles a continuous current of 40A with a 10-second burst of 50A and is slightly larger at 72 × 31 × 10.5 mm. Both feature the same 2S–4S LiPo compatibility and 5V\/2A BEC output.
