For small helicopters, every gram and every millimeter matters, so this ESC is much more appropriate than a larger 80A, 120A, or 150A Platinum ESC.\n\u003c\/p\u003e\n\n\u003cp\u003e\nIts 25A continuous current rating gives small helicopter pilots a clean current class for lightweight power systems, while the 40A peak rating provides short-duration headroom.
