Hi, I'm new to this site and new to the phantom. I have the fc40 version and I'm having a few issues with it. It won't going into gps mode. It flies perfectly fine in atti mode but I'm not a very experienced flier yet so I need the gps features. When I plug it into the NAZA-M assistant it has no gps reading and will not allow fail safe to work. I bought a new compass thinking that was the issue but it didn't fix it. It's had no hard wrecks. I really need some help! Thanks
