FIMI X8 Mini 3 Longer Distance Flight 

Have had this FIMI X8 Mini 3 for several weeks. This is the first for me to take it out for a longer distance test flight. The route has been used for all of my distance flights, because this route is challenging as a big forest at a higher attitude actually blocks all transmission/video signals.
Hence, the drone disconnected at about 1.3km, a place where most of my lower end camera drone failed, and an auto Return-To-Home was activated. In general, this FIMI X8 Mini 3 is approximately the same as my DJI Mini 3, DJI Mini 4K, etc. But, it is not as good as my DJI Mavic Air 3 with the RC2 controller.
My conclusions are:
(1) In terms of flying distance along the same route, this FIMI X8 Mini 3 is very good.
(2) Image quality at the default parameters with -0.3EV compensation is rather good. It is vivid and saturated. However, the exposure system may not be able to adjust fast enough so that I have to post-process with my video editor. The major issue is the exposure meter. Well, this is a minor issue.
(3) In terms of battery life, this FIMI X8 Mini 3 is good. I flew about 15 minutes and the battery power still had about 50+ % left.
Will do more test in the near future.
