When I received my FPV QR Ladybird, I was entirely disappointed that I could not record video. A lot of search went into “can I record video with walkera ladybird”. All I could establish is that it is possible to connect a video cable to the radio, and then hook this to a DVR. Bulky and complicated setup.
What I did was to get a 808 car key cam off ebay, very cheap. Then I temporarily stripped out the “native” video transmitter and came to the solution shown in the video.
Hope this can be useful. Any info on better quality, lightweight camera to test in a similar setup is most welcome.

Concerning the flight with payload, the ascensional phase was quite smooth and the Ladybird can lift the weight of the 801 camera easily. The descent was more turbulent and in more that one case I was only able to control it and slow it down, but not to stop it (in short a few crashes occurred). No damages though.
