One of our motors (ArduCopter Hexa Ready to Fly) has stopped working correctly and we were wondering if anyone had some pointers for how to solve this. It stopped working in the field after about 30 minutes of use, when switching out for our 3rd battery.
Now, whenever it starts up we get "musical tones" + "3 beeps (for 3 cell lipo)" + "1 confirmation beep". Then 5 of the motors are still, but the 1 broken one that doesn't spin during flight keeps jerking back and forth, and the Hexarotor beeps repeatedly! Here is a video of it:
From reading around, it seems this could be due to either (1) something not plugged in or (2) a radio problem. We've taken apart the bottom to ensure everything is plugged in, and put it back together and are still getting the same behavior. Yesterday was the first time we used the XBee telemetry if that matters, and the telemetry works fine.. Any help would be greatly appreciated. Thanks.
