Greetings to everyone here on the board. I am a relatively new P2V owner and have been lurking around these parts for a bit. Lots of very experienced users here and I'd like to thank you all for sharing your knowledge. Anyway, in the last couple months, I've had one fly away and since then I've been trying to figure out why it happened. Short version is this, I launched the Phantom Vision from an outdoor handball court (cement floor surrounded by metal fencing) with the intent of filming a game from about 25" overhead. After hovering for a couple minutes, the Phantom ended up slowly flying off in a random direction about 1,000 feet. After a moment of panic (I lost FPV and controls didn't seem to work), I ran after her and was able to reestablish contact over a heavy intersection and strip mall. LUCKILY, I got her to come back to me.. The Phantom was calibrated and achieved satellite lock prior to flight. Winds were light around 5-10mph. After returning to the handball courts, I flew her again, but kept her within arm's reach (boring!!) because I was so spooked. So my questions is this, would flying the Phantom over a cement floored area surrounded by metal fencing interfere with the compass? I've been doing some testing over large cement areas and the P2V does seem to "wobble around" more than compared to open grass. Ideally, I'd like to set her to hover above the heads of the players so I can record video, but thus far, it is not possible without a lot of manual position corrections (and wobbly video). She seems to wonder around a 5-8 foot area. Any insight or tips would be appreciated. Oh, and for those suffering through snow or bad weather, here's my greetings from South Florida: EDIT: are img tags not displaying images for new users?
