Hobbywing Platinum Pro 120A V4 Brushless ESC (3S - 6S / 10A BEC)

Unleash the full potential of your high-performance model with the Hobbywing Platinum Pro 120A V4. Engineered specifically for demanding 500-550 class RC helicopters and 70-90 class fixed-wing airplanes, this premium Electronic Speed Controller (ESC) delivers unbeatable reliability, lightning-fast response, and industry-leading thermal efficiency.

Featuring a powerful 32-bit processor and advanced governor algorithms, the Platinum Pro 120A V4 is the ultimate choice for both precise aerobatics and hardcore 3D flying.

 Key Performance Features

 Advanced 32-Bit Processor & Excellent Governor

Equipped with a high-performance 32-bit processor paired with highly advanced algorithms, this ESC delivers incredibly precise motor speed governing. With adjustable governor sensitivity, you can fine-tune the head speed to perfectly match your unique flying style.

 Powerful 10A Switch-Mode BEC

No need for a separate receiver pack! The built-in high-power, switch-mode BEC features a continuously adjustable output voltage ranging from 5.0V to 8.0V (in 0.1V steps). Delivering a massive 10A continuous and 25A peak current, it easily feeds the most power-hungry high-voltage (HV) digital servos.

 Innovative Heat Dissipation & "Duo" Stacking Structure

Heat is the enemy of performance. Hobbywing’s innovative "duo" stacking structure allows components on both sides of the dual-sided PCB to quickly conduct heat straight to the rugged CNC-machined aluminum alloy case. Each cooling slot and fin is aerodynamically optimized to keep operating temperatures critically low.

DEO (Driving Efficiency Optimization) Technology

DEO (Active Freewheeling) technology significantly improves throttle response, reduces operating temperatures, and increases flight efficiency. Enjoy longer flight times and a much cooler ESC.

 Super Soft adjustable Start-Up

Tail-drift issues during startup are a thing of the past. The Platinum 120A V4 features an extremely smooth and linear startup. The start-up time can be adjusted between 8 and 25 seconds, providing a perfect, reliable spool-up every single flight.

Built-in Sparkproof Circuit

The integrated sparkproof circuit effectively eliminates high-voltage sparks when connecting your LiPo batteries, protecting your high-quality connectors and extending their overall lifespan.

 Main Applications

• RC Helicopters: Ideal for 500-550 Class Helicopters (with main blades from 470mm to 575mm).

• Fixed-Wing Aircraft: Excellent for 70-90 Class acrobatic and sport airplanes.
