HOBBYWING SKYWALKER 20A 4S V2 MINI SPEED CONTROL Features High performance 32-bit microprocessor (Running frequency up to 96MHz) has excellent compatibility with various types of motors. DEO (Driving Efficiency Optimisation) Technology greatly improves throttle response & driving efficiency and reduces ESC temperature. Separate programming cable for connecting ESC to a LED program box and allows users to program the ESC anytime, anywhere. Normal/Reverse brake modes (esp. reverse brake mode) can effectively shorten the landing distance for the aircraft. Search mode can help users find the aircraft by the alarm beeps after the aircraft falls into the complex environment. Multiple protection features like start-up, ESC thermal, capacitor thermal, over-current, over-load, abnormal input voltage and throttle signal loss effectively prolong the service life of the ESC.
