I just bought a Phantom 2 with H3-3D today and the gimbal was working when I first turned the unit on, then a little while after updating the firmware the go pro would just face down and not move at all. Now the gimbal does not move at all. Power is getting to the go pro as it's light comes on when I turn the phantom on but gimbal does not move at all. I am very new to anything RC and after hours of research online cannot figure out what to do. Anybody have any ideas what I could be doing wrong? Thanks!
