Hobbywing Platinum 120A V4 Brushless ESC For RC Model Description: 1. Super Soft Start-up \u25cf Platinum V4 serial products allows the motor to start extremely smooth and avoids tail-drift issues that helicopters experience. \u25cf The start-up time is adjustable from 8 to 25 seconds, this will definitely create a perfect starting point for every flight. 2. Excellent Motor Speed Governing \u25cf High-performance 32-bit processor with a prossesing frequency of 72MHz combined with advanced algorithm optimizes the speed governing. \u25cf Together with the adjustable governor parameters it will guarantee every pilot a precise and efficient control experience. 3. High Voltage Built-in BEC \u25cf 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 at their peak. 4. DEO Technology The DEO (Driving Efficiency Optimization or so-called “Active Freewheeling”) technology implemented in the ESC has multiple advantages. \u25cf A very Rapid response to throttle change. \u25cf Higher driving efficiency, longer flight time. \u25cf Lower ESC temperature and a much more reliable operation during flight. 5. Other Features A separate program port for connecting programmer on this ESC allows user to \u25cf Program ESC, \u25cf Check flight data include minimum voltage, maximum temperature, standardized RPM and speed curve (in Heli Governing Store mode) of the flight parameters recorded by the ESC, \u25cfUpgrade ESC firmware with a mutifunction LCD program box or a WiFi Module & our Apple\/Android phone App. 6. Four Brake Modes \u25cf This Platinum 80A V4 ESC has “Brake Disabled, Normal Brake, Proportional \u25cf 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 selected based on the position of radio throttle stick; in reverse brake mode, the motor rotation can be changed via a spare transmitter channel. 7. Multiple Protections \u25cf 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.
