In 2015, HOBBYWING released Platinum-HV-160-V4 and Platinum-HV-200A-OPTO-V4 two high-end aircraft ESCs which are greatly welcomed by the market for its outstanding stability, great performance and reasonable price. For further expanding the V4 series, now HOBBYWING release Platinum-80A-V4 (6S), Platinum-120A-V4 (6S), Platinum-HV-130A-V4 (14S) and Platinum-HV-130A-OPTO-V4 (14S) four ESCs for 450L-700 class helicopters with the blade length ranges from 380mm to 690mm.
2016 is a new and different era for fixed-ring aicraft and helicopters, HOBBYWING seize the opportnunity, release new high-perfromance products. Undoubtedly, this will help HOBBYWING to gain a big market share once again.
Platinum V4 series of aircraft ESCs feature:
Excellent Motor Speed Governing
High-performance 32-bit processor combined with advanced algorithm makes the motor speed-governing excellent for different conditions. With the adjustable sensitivity of speed-governing, every pilot can find the most suitable settings for his helicopter.
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.
The built-in switch mode BEC with a continuously adjustable output voltage, range from 5V to 8V(step: 0.1V). It is certain to put out the power you need for rapid, precise steering servo operation.
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
The 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.
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.
A separate programming port for connecting the programmer on the 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
Built-in Sparkproof Circuit*
Built-in sparkproof circuit effectively eliminates sparks produced at the “powering-on” moment and prolongs the connectors' lifespan.
（*Note: Only Platinum-HV-130A-V4 & Platnium-HV-130A-OPTO-V4 have this unique feature.）
