I bought myself the GEPRC CineLog 25 V2 mini drone alongside with the DJI Goggles 2. I'm amazed by the quality and stability of the video link, however, so far I wasn't able to test the long range ability of this system because this drone is simply too small and too slow to fly far enough. However, my first test flights in the forest show that the signal penetration is on par with my old 5.8 ghz analog video system.
