I was flying my newly finished 5 inch drone today. I flew two batteries and everything was fine. When I was flying my third battery and about 50 yards from my car, the osd flashed rxlost and disamred. Thankfully I was only about 10 or so feet off the ground so the only damage was a little bit of mud and a ripped battery casing. I was flying from inside my car because it was cold and windy out. Did I lose connection because of this, or is there a actual issue? I had gone farther than that previously. In hindsight it probably wasn't smart or safe to fly from inside my car bu thankfully I had a spotter with me.
