Hobbywing RC Aircraft System Platinum 120A V4 Brushless ESC Excellent Motor Speed Governing

DEO Technology

The DEO (Driving Efficiency Optimization or so-called “Active Freewheeling”)
technology implemented in the ESC has multiple advantages.
• A very Rapid response to throttle change.
• Higher driving efficiency, longer flight time.
• Lower ESC temperature and a much more reliable operation during flight.

Other Features

A separate program port for connecting 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 parameters recorded by the ESC,
• Upgrade ESC firmware with a mutifunction LCD program box or a WiFi Module & our
Apple/Android phone App.

Four Brake Modes

This Platinum 80A 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 selected based on the position of radio throttle stick; in reverse
brake mode, the motor rotation can be changed via a spare transmitter channel.

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.
