Core Features & Benefits
1. Mainstream 5.8G Band with 48 Channels for Full Compatibility
Adopting the industry-standard 5.8GHz analog VTX frequency band, it delivers low-latency, clear and stable video transmission, fully compatible with most FPV goggles, VTX receivers and display devices on the market. Built-in 48 independent working channels cover mainstream frequency groups, which can be flexibly switched according to the on-site electromagnetic environment to effectively avoid co-channel interference. It supports multi-drone simultaneous flight and formation operation, suitable for FPV events, group aerial photography and multi-drone industrial inspection scenarios.
2. 5 Precision-Adjustable Power Levels with 4W Max Long-Range Performance
It supports free switching of 5 transmit power levels: 25mW, 400mW, 1000mW, 2000mW and 4000mW (4W):
- The 25mW low-power mode is suitable for indoor practice and close-range test flight, with low electromagnetic interference and lower power consumption for daily casual flight;
- Medium power levels meet the needs of daily freestyle flight and ordinary venue long-range flight, balancing battery life and transmission distance;
- The maximum 4000mW (4W) high-power mode significantly improves signal transmission distance and diffraction penetration capability, easily coping with extreme scenarios such as ultra-long-range flight and complex terrain obstruction, ensuring stable and uninterrupted video.
3. Wide 2-6S Direct Power Supply for Full Drone Compatibility
It supports a wide input range from 2S to 6S LiPo batteries directly, without additional step-down or voltage regulator modules. It is perfectly compatible with mainstream 3-6S racing drones, long-range drones and small and medium-sized industrial UAVs, greatly reducing the installation threshold, and is convenient for both new drone assembly and old equipment upgrades.
4. Reinforced Thermal Design for Stable Long-Time Full-Power Operation
Optimized heat dissipation design for high-power operation scenarios, adopting high thermal conductivity structure and optimized high-current circuit layout to quickly dissipate heat generated during full-power operation, effectively control the overall temperature rise, and avoid power attenuation, signal jump and even equipment damage caused by high temperature. It ensures stable operation during long full-throttle long-range flight and continuous operation, and improves equipment service life and reliability.
5. Standard AV Interface for Plug-and-Play Easy Installation
Adopting industry-standard analog AV video input interface, it is fully compatible with various analog FPV cameras and flight control OSD character overlay systems, with stable video signal transmission. The installation and wiring are simple and convenient, and it can be put into use quickly without complicated debugging. The compact and lightweight structure design fits mainstream frame mounting positions without adding excessive weight burden to the aircraft.
