Spetktrum Firma 200A Brushless Smart Marine ESC - 12S

The Spektrum Firma 200A Brushless Smart Marine ESC - 12S (SPMXME1200) is a high-current speed controller designed for large RC boats. With robust 200A continuous output and support for 6–12S LiPo power, it provides confident control of powerful brushless setups on the water. Built-in Smart technology complements Spektrum systems, while a water-resistant construction and protective features help keep your boat running smoothly.

A switch-mode BEC delivers a strong 8A continuous (25A peak) at selectable 6V, 7.4V or 8.4V, giving headroom for demanding servos and onboard electronics. Auto cutoff and overload protection add peace of mind during hard runs. Connectivity is straightforward thanks to an IC5 battery connector and 8mm bullet motor outputs.

Compact dimensions make installation easier in a variety of hulls, and the unit is optimised for RC large boat applications where efficiency and reliability matter.
