“Vishchun-M” is a compact aerial FPV repeater designed for integration with a DJI Mavic, extending communication range and stabilizing the video signal.
The Vishchun-M airborne FPV repeater for DJI Mavic 3 / 3E / 3T BlueBird Tech series drones is a compact, lightweight and effective device designed to provide the most stable analogue connection between the drone and the operator. Video frequencies: 1.2 GHz/5.8 GHz. The DJI Mavic acts as the repeater carrier. Installation takes just a few seconds — the repeater is quickly attached to the Mavic body using two nylon ties without complicated assembly or tools.
The device is powered by a modified Mavic battery connected via an additional lead-out (the battery is not included in the kit but is compatible with existing DJI Mavic 3 drones). This eliminates the need for separate batteries and maintains a lightweight construction. The enclosure is designed not to interfere with drone cooling – motors do not overheat, and ventilation systems operate without restrictions. Premium-class antennas ensure long range and stable signal quality. The relay supports remote video channel switching, which helps avoid interference and improves signal quality in complex environments (e.g., “STHORA” jamming).
The relay is designed for high-quality transmission of control and video signals from an FPV drone to the operator — even over long distances, in areas with complex terrain or dense urban development. It is especially useful in situations where direct transmission is obstructed or when the operator is working from cover, behind hills or buildings. With the relay, you receive a stable video feed and precise control in real-time — without delays, interference, or signal loss.
Ultra-lightweight design: Minimal device weight adds negligible load to the drone and has almost no impact on motor heating.
Ergonomic housing design: All components and mounts are optimized specifically for DJI Mavic drones.
Premium reception antennas: High-quality directional antennas ensure stable signal even in harsh environments.
Quick and reliable mounting: The fastening system allows for rapid installation without tools.
In-air video switching: Supports preconfigured video channel switching by the pilot when interference (e.g., “STHORA”) is detected.

An aerial repeater is a drone or module deployed in the air that transmits signals between the operator and the UAV, extending the control and video communication range.
An aerial repeater allows you to extend the flight range of an FPV drone, stabilize the video signal, and maintain control in challenging terrain.
Depending on the model and operating conditions, a stable video and control link can be maintained at distances of up to 15 km or more.
The operating altitude depends on the model but can range from a few meters to several hundred meters, which improves line-of-sight signal quality.
Yes, there are models that can be integrated with carrier drones or platforms such as the DJI Mavic for signal relaying.
An aerial repeater operates from altitude and improves line-of-sight signal conditions, whereas a ground repeater is installed on a mast or a fixed position.
You should consider range, hovering altitude, autonomy, compatibility with the carrier drone, and operating frequencies.
You can order aerial repeaters and receive a consultation through BlueBird Tech’s official communication channels.
