Would love some help here. Installed the Zenmuse Gimbal H3-2D last week. Everything was going great but within the week something happened. Now I can't get my motors to start up. I have the double-blinking, ready-to-fly green lights. My controller is still in contact (lights turn yellow or red when I turn it on and off and I can tell my quadcopter to calibrate the gps) but when I pull both sticks down - nothing. The blades all rotate fine and there was no crash that started this. Just one time it was working, the next it wasn't. Any suggestions? I'm really at a loss.
