So i just got into the phantom 2 vision plus world. When a local sold me his two for a fairly good price.. the down side is when i try to spin up the motors i get a red light flashes 5 times, the dubble yellow flashing lights. Pauses then duble yellow again. It continues like this for a while. The odd part is they both do it. So i am wondering. Does anyone have any ideas why they are doing this?
