I was out shooting this morning in the country...beautiful, pristine country church in rural Ohio, surrounded by massive soybean fields. On my third battery, my Inspire instantly started to lose control...I was in GPS mode and thought that I had checked values, etc. When I turned my craft on, I do member moving it when it was going through it's initialization process, which was probably dumb. When I recognized that I didn't have control and that the craft was starting to "take off," I switched to atti mode and was able to regain control and land. There was a fairly significant wind and the process was unnerving. I then shut everything down, restarted everything and was able to continue flying in GPS mode without issue. Had I not been on this forum and read several posts dealing with this issue, advising the immediate switch to atti mode, this could have been really bad. The other thing I'm going to do, through advice on this forum...is to actually practice flying in atti mode in an open field...not just assume I can do this without any practice. I don't mean to be a homer, but this forum gives you stuff that will never be included in an instruction manual. Thanks!
