Finally had some time to test out a little further on the distance, since FPVLR trusts his product, and gave me the challenge.
It was not the most desirable wind condition but it seemed calm enough to try. (later checked when back and it was a about 3.5 M/S sideways drift speed at 30 meters up. Again launched it and set a high home point before trucking off in ATTI mode.
Buzzed out to 2500 meters which was my set goal. FPV was solid all the way out, but on the 180 turn around to face my location I lost signal. Mind you, the antenna is placed next to my left rear leg at bottom, but obviously my gimbal, camera and tracker are blocking some of the line of sight.
I figured since I had no FPV I would throw it into home lock, and pull right stick full down. I was getting intermittent FPV flashes and was noticing distance was actually increasing! I ended up at 2740 meters before turning it around to get actual FPV to analyze what the hell was going on. Once the antenna had a clear shot of me for FPV it was slightly showing noise on screen but I was happy as hell just to see what was actually going on.
I can only imagine if I would have kept pulling the right stick down in H/L where it would have ended up. Like I've said before I'm still new to this stuff so my heart was probably going around 160-180 beats a minute. Thus thinking mode was definitely not there. I can now understand if a really new person does this, he is definitely tempting fate in which he will be screaming fly away when it is actually pilot error.
Once I had the bird back from this flight I still had 52% of battery and voltage was bouncing between 11.0-11.1
I guess for now this will be my furthest flight until I can figure out a better antenna location and make **** sure wind is around zero.
