Before getting the shell back together (so many screws, so little time) all seemed to be working fine. I was even able to fire up the motors by disabling the GPS on the ST-10. Now however when I turn everything on, the ST-10 gives me a welcome pilot and connects to the camera, but the indicator light on the bird is flashing a rapid blue, as if it isn't connected. I don't see any telemetry information on the ST-10. I can't control the tilt on theCG-o3. Previously I was able to access the GPS and calibration settings without the camera attached. Now with no camera attached that gear button is greyed out. With the camera attached I get access to those settings, but the GPS and Calibrate options are greyed out. I'm adamant about having to pull it all apart again. Is there anything else to check? As I said it was all looking good until got all the screws back in. All sensors and motors check out fine when connected to the GUI
