I'm having trouble getting my controller to connect. Recently installed the H3-2D and things were going great. But then my quadcopter suddenly just stopped arming the motors. Everything else seemed alright - green flashing lights after finding the satellites. The controller seemed to be connecting in that I could tell my phantom to calibrate the gps and it seemed to respond when I turned the controller on and off, but yesterday I was finally able to get to a PC (I'm a mac guy) to plug it in to see if the firmware needed updating or to just calibrate things. But when I plugged things in, I found that moving the controller sticks didn't do anything onscreen. So now I think my problem is a controller to phantom problem. Any ideas for what's wrong or what my next step could be?
