Today I finally got to fly at my brothers ranch. I flew around a bit and then took off to see the landscape. I had no connection issues until I reached bit over 1200m, at that point I had just first warning of image transmission quality. Control was supreme, I could have gone further, but decided to turn back since I had been flying before, it was -18C outside and I knew I had to fight the wind on my way home. This flight was with Russian 3.1.18 SW, latest FW and ARGtek antennas, panel antennas on the controls and omni-directional on the center.
Can't wait to fly there at summer, they have a small cottage by the river just 2,5km away, I think I could easily fly there and back.
