I am experiencing a loss of control signal at 250 feet. I live out in the country with nothing around to interfere with the transmitter. I have 30+ flights on my phantom 2v+ 3.0 all the software is up to date and has flown reliably in the last couple of weeks. Yesterday I was try to take pictures of the sunset and lost signal at 250' straight up. Today I flew it with GS went out to its first waypoint, lost control signal on the way, flew to its 2nd waypoint and landed nicely in the cow pasture. The video feed was still working and I watched it set down on my iphone. I flipped it to fail safe as I saw it descending and I just continued to land. Everything is charged Compass calibrated before every flight Software 3.12 Iphone 6+ FCC mode on What am I missing?
