Core Features & Benefits
1. Mainstream 5.8G Band with 48 Channels for Strong Anti-Interference
Adopting the industry-standard 5.8GHz analog VTX frequency band, it delivers low-latency video with accurate color reproduction, 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 competitions, group aerial photography and multi-drone inspection scenarios.
2. 5 Precision-Adjustable Power Levels for Full Scenario Adaptation
It supports free switching of 5 transmit power levels: 25mW, 200mW, 800mW, 1000mW and 2500mW:
- The 25mW low-power mode is suitable for indoor practice and close-range test flight, with low electromagnetic interference and lower power consumption;
- Medium power levels meet the needs of daily freestyle flight and ordinary venue flight, balancing battery life and transmission distance;
- The maximum 2500mW (2.5W) high-power mode greatly improves transmission distance and diffraction capability, easily coping with ultra-long-range flight and complex terrain operation scenarios.
Users can switch according to flight scenarios, balancing compliance, battery life and transmission performance.
3. Ultra-Wide 2-8S Voltage Support for Full 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 aircraft ranging from small 2-4S racing drones to large 6-8S long-range drones and industrial UAVs, greatly reducing the installation threshold, and is convenient for both new drone assembly and old equipment upgrade.
4. Optimized Thermal Design for Stable Long-Time Full-Load Operation
Adopting an efficient heat dissipation structure and optimized high-current circuit layout, it quickly dissipates heat generated during high-power operation, effectively controls the overall temperature rise, and avoids power attenuation, signal instability 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 to the aircraft.
