Hi everyone!
I'd like to share my recent project with you and get some feedback from the community.
About the Project
The idea is simple: stream video and control an FPV drone over the internet - specifically, using 4G mobile networks.
And it's not limited to quadcopters - any land, air, or water platform can be controlled, as long as it supports the CRSF protocol and has a stable 4G signal.
Advantages compared to traditional control systems:
Currently, there's a cross-platform desktop application for drone control using gamepads (XBOX, Playstation, etc.) or remote controllers like Radiomaster TX12.
An OSD overlay provides basic telemetry, a compass, and waypoint markers over the live video stream.
A separate OpenStreetMap-based window shows the real-time position of the drone.
Waypoints added to the map are instantly shown in the OSD compass with live distance indicators - just like in video games.
There's also a mobile app that allows control directly from a smartphone.
It features on-screen virtual sticks, and supports external gamepads and remote controllers via USB.
Telemetry and the live map are also available on the phone.
Quick startup process:
Questions to the Community:
1. Legal considerations
I hold a flight license and understand the restrictions, including the ban on BVLOS (beyond visual line of sight).
But is it allowed to use 4G for control if all other rules are respected - for example, flying in open fields, within line of sight, and away from people?
Could there be issues getting insurance due to the "custom" configuration of the drone?
2. Legality of developing and sharing this technology
Is it permitted to build such drones privately? What about publishing and sharing details of the system?
Obviously, such technology could be used for non-peaceful purposes - could that raise legal concerns?
3. Potential interest and applications
Do you think this system would be interesting for hobbyists, rescue services, or other civil organizations?
What kinds of use cases do you see? Does it make sense to continue developing this project?
I’d really appreciate any feedback - especially from those who’ve worked on similar challenges or are active in related fields.
If interest is high, I’m open to providing a deep dive into the architecture and potentially publishing an open-source version of the software.

And it's not limited to quadcopters - any land, air, or water platform can be controlled, as long as it supports the CRSF protocol and has a stable 4G signal.
Advantages compared to traditional control systems:
- Unlimited flight range - it's only dependent on mobile network coverage and battery capacity.
- Low latency for both video and control signals - less than 100 ms.
- Automatic stabilization during short-term signal loss and Return-To-Home on total signal loss (depending on flight controller settings).
- Video quality: 960x720 at 60 FPS (can be adjusted depending on available bandwidth).
- Total build cost: approximately $280–350 (depending on configuration and component prices).
- Only standard, widely available parts are used - everything can be bought from common online marketplaces. No exotic components required.

Quick startup process:
- Insert a SIM card into the drone
- Launch the control app on phone or PC
- Connect power
- After ~10 seconds, the drone is ready to fly
