Here is the installation and test flight of the FY21AP FPV stability, return to launch and onscreen display system from FeiyuTech of China.
The system is installed in a HobbyKing EPP FPV RC model plane, which is designed specifically for first person view flying.

If you've got any serious money tied up in an FPV model then this device is a great piece of insurance and can make the whole FPV experience a far more enjoyable one.
