6. Dissipador de calor: The heat sink is included by default. Removal of the heat sink eliminates weight, but may cause overheating of the unit. It is recommended not to remove the heat sink. If necessary, please be cautious when flying and once your battery is connected, fly immediately. The airflow will keep the unit cool.

Funcionament

Once installed and powered, the RunCam Link module provides a digital FPV video feed. It supports various transmission power levels (25mW/200mW/500mW/700mW) and offers low-latency video for responsive control. The embedded DJI remote controller receiver allows for direct connection without additional receivers, simplifying flight preparation.

The system operates on 5.725-5.850GHz frequency and can achieve transmission distances of up to 4 km (FCC/SRRC) or 0.7 km (CE). It supports both Low Latency Mode (720p 120fps) with 21-28ms latency and High Quality Mode (720p 60fps) with 30-40ms latency.
