Hobbywing FLYFUN 40A V5 ESC (3-6S) for RC Airplane
ESC which features a high-performance 32-bit ARM M4 microprocessor (with a running frequency of up to 72MHz) is compatible with various brushless motors. Microprocessor powered by a separate DC regulator has better anti-interference performance greatly reduces the possibility of losing control. DEO (Driving Efficiency Optimization) Technology greatly improves throttle response & driving efficiency and reduces ESC temperature. Built-in high-power BEC with output voltage adjustable among 5.2V, 6.0V and 7.4V. The BEC module is separate from other circuits on the ESC, so the normal BEC output can be guaranteed (when issue like burnt power board happens) to
