I had a great flight last night (4th one), everything worked smoothly and landed the H at about 50% battery. Later on I decided to play with camera settings so I started everything up, the H and ST16 linked and I got a good video feed. A couple things I noticed right away....the camera would tilt but not pan (I verified that all the settings were correct), the voltage displayed on the ST16 was 0 and the main LED light on the H was blue and blinking rapidly. I put the battery back in the charger and the indicator light went from red to green in about 45 minutes. I plugged the battery back into the H, (battery was firmly in place), everything powered up normally, except for the blue blinking LED and other symptoms listed above. I attempted to power on the motors, but they did not respond. I connected the H to the GUI and the battery levels indicated 0% and I could not get a good connection to test the motors via the GUI. below is a screenshot of the voltage display from the ST16....thoughts? Also, does anyone know what the rapid blinking blue LED indicates? I can't find that on Yuneec's reference card.
