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 professional display devices on the market. Built-in 48 independent working channels cover all 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 operation with different frequencies, suitable for team flight, industrial multi-drone inspection and large FPV events.
2. 4 Precision-Adjustable Power Levels with Flagship 5W Long-Range Performance
It supports free switching of 4 transmit power levels: 250mW, 1000mW, 2500mW and 5000mW:
- The 250mW low-power mode is suitable for ground tuning and close-range test flight, with lower power consumption and less interference;
- Medium power levels meet the needs of daily freestyle flight and ordinary venue long-range flight, balancing battery life and transmission distance;
- The maximum 5000mW (5W) 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. Ultra-Wide 2-8S Direct Power Supply for Broad Drone Compatibility
It supports a wide input range from 2S to 8S LiPo batteries directly, without additional step-down or voltage regulator modules. It is perfectly compatible with various aircraft from 6-8S large long-range racing drones, fixed-wing UAVs to industrial inspection drones, 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
Specially optimized heat dissipation design for 5W high-power operation scenarios, adopting high thermal conductivity heat dissipation 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 output during long full-throttle long-range flight and continuous operation, and greatly 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 compact structure with universal mounting holes fits mainstream frame positions, with simple wiring and no complicated debugging required, enabling quick setup and use.
