Just wanted to post a hello to all the members. I'm totally new to RC and for that reason, chose a DJI FC40. So far, I like it a lot but I'm a little concerned that I'm experiencing frequent fly-aways. I keep the drone close by just for that reason. I live in a VERY remote area of central Delaware and have only flown it on my own property. Front yard is about 3 acres and surrounded by trees on three sides. Anyway, flights always start out fine but sometimes end in crashes. My last one, I had the drone hovering about 8ft above the ground. Was hanging there perfectly for about 30 seconds when it suddenly pitched right and flew off in the tree line. This is kind of more the norm than the exception. I'll be hovering and trying very small control inputs to gauge reaction and it all of a sudden takes off on it's own. I've updated the firmware/software and performed the calibration procedure, all of which didn't seem to help at all. My last flight was really strange, was testing the return home feature with the drone about 100ft away. It was a few feet off the ground and when I turned off the transmitter, the drone immediately climbed to approx. 50ft or so and moved back to where it had lifted off. I was very impressed at first but once it hovered for a couple seconds over the home spot, it pitched and dove into to tree line instead of landing. Any thoughts??
