HWI30214002,FlyFun V5 Sensorless Brushless ESC (40A)

The DEO technology (Driving Efficiency Optimization) implemented in the ESC has multiple advantages, such as:
Faster and smoother throttle response, better stability and flexibility during flight.
Higher driving efficiency, longer flight time.
DEO Technology / Active Freewheeling
Lower ESC temperature, more reliable operation.
Soft Start-ups & Reverse Brake
ESC programmable through Transmitter and LED program card (purchase separately).

High-power BEC: High-power switch-mode BEC with continuous/peak current of 8A/20A and adjustable voltage (5.2V, 6.0V & 7.4V) allows users to use more electronic devices or devices with higher power such as servos, flight controller, and lights on their aircraft.

Multiple protection features include: start-up, over-current, ESC thermal, capacitor thermal, overload, throttle signal loss (or Fail Safe), and abnormal input voltage effectively prolongs the service life of the ESC.
