Core Features & Benefits
1. BLHeli_S Open-Source Firmware for Precise High-Speed Response
Powered by the widely compatible BLHeli_S open-source firmware with flexible tuning options, it fully supports DSHOT300 and DSHOT600 high-speed digital protocols, delivering ultra-low throttle signal latency and responsive power output. It fully meets the high precision demands of racing and freestyle flight, and supports custom parameter tuning to adapt to different pilots’ operating habits.
2. 30A 4-Channel Output with Wide 2-6S Voltage Compatibility
Adopting a 4-channel independent drive circuit design, each channel delivers up to 30A continuous current, easily driving mainstream brushless motors such as 2207 and 2306 specifications to meet the power demand of 5-inch and 7-inch drones. It supports a wide input range from 2S to 6S LiPo, suitable for both lightweight practice drones and high-voltage long-range / freestyle builds, with wide application scenarios.
3. Optimized Circuit & Thermal Design for Reliable Operation
The high-spec PCB layout optimizes high-current paths, reducing line loss and electromagnetic interference to ensure consistency and stability across multi-channel output. Paired with an efficient heat dissipation structure, it quickly dissipates heat generated under heavy load, avoiding overheating throttling or power failure during long full-throttle flights, effectively improving flight safety and device durability.
4. Standard Stack Design for Easy Installation & Wide Compatibility
It adopts industry-standard mounting holes for 4-in-1 ESCs, enabling direct stack installation with flight controllers for clean wiring and greatly reduced assembly complexity. It is compatible with most mainstream flight controllers and airframes, fitting various models including 5-inch racing drones, 7-inch long-range drones, freestyle drones and practice drones.
5. Convenient Tuning & Firmware Upgrade, Beginner-Friendly
It supports online parameter adjustment and firmware upgrade via the flight controller, no additional programmer is required for easy operation. Pilots can customize throttle curves, protection thresholds and other settings according to flight needs, balancing ease of use for beginners and deep tuning demands for advanced pilots.
