Today was just 5-7Km/h wind at 120 meters and I did some long range test in "Smooth" transmission mode, which seems to work a little better as it's only transmitting 720p/30FPS video feed as opposite to the 1080p/30 option, and also checked wich of the flight modes could achieve longer range before RTH prompted you to return for the first time.
I managed to do 6.2Km flying in normal mode at full stick using brake mode instead of bypass, and returned in auto RTH mode, landing with a bit more than 30% battery left, so quite happy with the overall performance.
Normal mode at 40Km/h (half stick) achieved 5.6Km... it's a bit tedious as you have to fight the spring tension to maintain the speed, so it's a nice find that Normal mode full stick is being more efficient for traveling.
On sports mode full stick I only achieved 5Km before RTH prompted me to return, which was expected as the drone is flying less efficiently.
Transmission wasn't superb, but at least it didn't freeze/stutter too much and this time the bottleneck has been the battery, which is the ideal thing. Pushing the battery I calculate that about 7Km could be possible but it's wiser to try to land at 30% instead of 20, as at 10% the drone begins autolanding procedure and cuts the amperage of the motors down.
For the most part and watching how the air 2 vs the Mini 2 perform I expected a better signal performance for the Air2S transmission system, which is only true at lower ranges where the 4 antennas achieve further signal penetration. But at long range something is odd, maybe channel selection algorithm, maybe bandwith...
I usually fly under 2.5Km range anyways, where you have plenty of battery to work instead of burning it all travelling.
PS: The altitude increase you see in the table is due the the slope of the terrain, as I took off from the shore and went inwards to the mountains, wich end up being 231 meters tall according to the topographic map.
