Hobbywing Platinum 25A V4 – 3–6S Brushless ESC

Precision, efficiency and advanced control — from Hobbywing, at Aerobertics

The Hobbywing Platinum 25A V4 is a high-performance brushless ESC designed for pilots looking for precise throttle control, excellent efficiency and reliable operation in compact 3–6S electric models.

Featuring a powerful 32-bit, 72MHz processor and Hobbywing’s advanced control algorithms, the Platinum 25A V4 delivers exceptionally smooth and responsive motor management. Combined with adjustable governor parameters, it provides precise and consistent power delivery throughout the flight.

At Aerobertics, we particularly appreciate the Platinum series for its combination of compact dimensions, advanced programming options and refined throttle response — making it an excellent choice for demanding RC applications.

High-Voltage Built-in BEC

The integrated switch-mode BEC provides a selectable output of 6V or 7.4V, with up to 3A continuous current and 7A peak current.

This provides a stable and reliable power supply for your servos and onboard electronics, while allowing compatibility with modern high-voltage digital servos.

DEO Technology – Driving Efficiency Optimization

Hobbywing’s DEO (Driving Efficiency Optimization) technology, also known as Active Freewheeling, is designed to maximize the overall efficiency of the power system.

The result is:

• Faster throttle response and sharper reaction to throttle changes
• Higher overall efficiency, helping to extend flight time
• Lower ESC operating temperatures for increased reliability
• Smooth and precise motor control throughout the throttle range

Advanced Brake Functions

The Platinum 25A V4 offers several brake modes to suit different flying styles and applications.

The Reverse Brake function is particularly useful for fixed-wing aircraft, allowing the propeller to reverse during landing and significantly reducing the landing roll. It can provide a realistic braking effect while helping you bring the aircraft to a stop in a very short distance.

Available brake modes include:

• Reverse Brake
• Normal Brake
• Proportional Brake
• Brake Disabled

The braking force can be adjusted in Normal Brake mode, while Proportional Brake automatically varies the braking force according to the position of the transmitter throttle stick.

Comprehensive Protection System

Reliability is a key feature of the Platinum 25A V4. Hobbywing has equipped the ESC with multiple protection systems to help safeguard both the ESC and the model.

Protection features include:

• ESC thermal protection
• Capacitor thermal protection
• ESC overload protection
• Throttle signal loss / failsafe protection
• Low-voltage cutoff

These features help protect the power system under demanding operating conditions and contribute to a longer service life.
