I tried to fly my phantom 2 today and noticed some strange Led indicators I've not seen before and can't seem to find the meaning for. When starting up the normal sequence was observed. The indicators were flashing green and a few red as it looked for GPS then when it got home lock the rapid flashing greens were followed by an equal amount of rapid flashing red. When it got plenty of satellites the usual slow flashing single green was observed followed by a set of fast flashing red every 3 single flashing greens. It seemed to fly ok but I aborted after a minute as I was unsure what it meant.
