A friend of mine lost his P2V+ today ..... fly-away I guess. He had been flying for 10 mins with no problems. Then I suspect it got to far away as he lost contact. On previous flights he has tested the RTH feature by turning off the RC and it has always worked. This time he tried and it just continued on in the opposite direction. My question is, if the home point for some reason is not set during take-off is the home point from a previous flight retained? Reason I asking is that is the direction it took off towards. (unfortunately there was a lot of water between him and the previous home point).
