Hi Yves,
Nice to see you around. Just to mention that I am still interested to do a product review for you (5.8 Ghz DJI video downlink) but, as you are well aware, its been quite cold and windy and this reduces my flying quite a bit. Still getting my 2-3 flying session per week as weather permitting. I have used the video Tx on F550 rigged for video and F450 FPV rigged for FPV. I recently got some Fatshark Attitude SD Base which works perfect with the DJI system. Collecting more data, the review will just cover a broader spectrum of equipment interface and MR set-ups.
Cheers
