Trying to find out what is going on with my phantom, i had it out last night for a small flight, when i hooked up both batteries (i use 2 when flying) i managed to get the lights to come on like normal with the 2 stock batteries and flew it for a short flight, the red light on the phantom kept flashing continously, at first the yellow and green came on for a brief moment. I looked at my FPV screen it was showing almost 13 volts for the batteries which is good, and after the normal time for the phamtom to warm up and even though the red light was flashing, the OSD was showing more than 8 satalites it was picking up. The motors fire up like normal, just did not want to fly it just yet until i find out what is going on. I hooked up the drone to the naza m assisstant, it was showing no problems, voltage was good although i was getting a low voltage warning which made no sense at all since the voltage showing was good in the assisstant, i checked for calibaration it said none was needed, i checked the compass plug on the landing skid it was showing it was plugged in ok. I charged all the batteries, even the 2 multistar ones again to make sure they were topped up. I have rechargable batteries for the TX even charged them up. This morning in the dining room i tried hooking up the 2 multistar batteries same thing the red light starts flashing after a brief moment , i tried the 2 stock batteries the same thing happend, with the props off i tried to start the motors nomally worked all fine. If any one has some ideas they will be welcomed. I intend to take off the top of the drone body to double check everything is still good with the hookup for the PMUv2 and the DJI OSD.
