I've only flown my XSP on four separate occasions, but I believe I'm getting more instances of magnetic interference each time I fly....the last time being so annoying that I didn't even make it through one battery!!! The first three times I flew at a very open spot at a local park, and the last time at a soccer field at a local high school. I don't see any power lines or cell towers close by. I guess I need to try another spot, but I want something very open, since I'm so new at this, and I'm having a difficult time finding places close by. The app says my firmware is up to date. Just curious if it's operator error or if anyone else has had similar issues or can tell me what else I need to check or do. Thanks!!!
