So ive taken my phantom 2 out for a few flights and worked like a charm. Decided to finally add the fpv setup to the mix and now ive got problems. I wired up an immersionrc 5.8 600 transmitter and iosd mini. Now i took it outside, did a calibration dance and got two sets of rapid flashing green indicating homelock and sat lock. then i get a slow green flash. fire up the motorsand take off and get a steady rapid red flashing and it auto lands each time. I had two bars on the battery when doing this. what could be wrong?
