Something else must have happened there in terms of conditions then. I bough my P3A a month ago and started flying it with 1.04 FW the latest one. 4km flight with the itelite DBS antenna and no loss of signal but i turned back cuz i was worried not to loose the bird.The fw version i think it was 1.19 when i went 6KM.I was at the same location both times.With the latest fw and the DBS antenna after almost 4KM i lost completely the signal.
