Hobbywing Platinum 120A V4 ESC (3-6s Lipo) 10A BEC

Hobbywing Platinum 120A V4 ESC (3-6s Lipo) 10A BEC brushless ESC for radio controlled helicopter.

What is the particularity of Hobbywing ESCs ? They simply have the best "governor mode", which is of great interest to rc helicopter pilots !

Excellent electric motor governing speed :

High-performance 32-bit processor with a running frequency of 72MHz combined with advanced algorithm optimizes the speed governing. Together with the adjustable governor parameters guarantees every pilot a precise control experience.

High Voltage Built-in BEC :

The built-in switch mode BEC with an adjustable voltage range from 5V to 8V, a continuous current of over 10A and peak current of 25A can supply enough power for your HV servos to operate efficiently.

DEO Technology :

The DEO (Driving Efficiency Optimization, or so called "Active Freewheeling") technology implemented in the ESC has multiple advantages.

  • Quicker response to the throttle change.
  • Higher driving efficiency, longer flight time.
  • Lower ESC temperature and a more reliable operation.

Four Brake Modes :

This Platinum 120A V4 ESC has "Brake Disabled, Normal Brake, Proportional Brake and Reverse Brake" four brake modes. The brake amount is adjustable in normal brake mode; in proportional brake mode, the brake force will be automatically allocated based on the position of the radio throttle stick; in reverse brake mode, the motor rotation can be changed via a spare transmitter channel.

Super Soft Start-up :

The ESC makes the motor start extremely soft and avoids tail-drift issues of helicopter.The start-up time is adjustable within 8 to 25 seconds, this will definitely create a perfect starting point for every flight.

Multiple Protections :

Multiple protection features include, ESC thermal, capacitor thermal (HOBBYWING-patented technology), ESC overload, throttle signal loss (or Fail Safe), and low voltage cutoff effectively prolongs the service life of the ESC.

Other Features :

A separate programming port for connecting the programmer on this ESC allows user to

  • Program ESC,
  • check flight data include minimum voltage, maximum temperature, standardized RPM and speed curve (in Heli Governing Store mode) of the flight data recorded by the ESC,
  • Upgrade ESC firmware with a multifunction LCD program box or a Wi-Fi Module & our Apple/Android phone App.
