Cyclone 45A BLHeil_S ESC
The ESC utilizes a 6-layer, 3-ounce copper-thick, high-quality PCB. This design employs a layered layout that separates large current pathways from small control signals to enhance anti-interference capabilities. The gold plating on the PCB surface effectively improves current resistance and heat dissipation.
An integrated RGB multi-color LED provides bright illumination for night flights, making them even more striking. The ESC supports BLHeli-S and DShot 150/300/600 digital throttle signals, offering robust anti-interference capabilities and quick response times.
By default, hardware PWM is enabled, and the Damped Light hardware PWM drives the motor, resulting in low noise and smoother throttle response. The Damped Light mode, coupled with a regenerative braking function, makes motor deceleration more sensitive and effective.

- Gold plated PCB
- Regenerative braking function
