I'm very puzzled by what happened this afternoon.
Last night I planned a 12 minute waypoint mission (short enough to give a generous margin for battery life). Cruising speed (26mph) was selected for every waypoint. The route included quite high hills, so the waypoints changed from 250ft altitude to 950ft partway through the route.
Everything went well at first, then I lost signal (which didn't worry me too much since that's often happened). But the signal was lost for a worryingly long time, and when I looked at the data, it said the craft's speed was only 8mph. I know it might have been climbing steeply at that point, but that reduction in speed still seemed odd. And then suddenly 'returning home' came up on the screen. I just couldn't figure out why this should happen - I launched with a full battery and battery was at about 60% when I lost signal, and in any case, doesn't Litchi just land the craft wherever it happens to be if the battery runs too low on a waypoint mission?
The route on the map confirmed that RTH was in progress, as it was taking a much more direct route back than the waypoints would have taken it. Then another odd thing happened - the video stopped recording. I switched it on again but a few seconds later I heard 'recording stopped' again. Then every time I started the recording, it stopped again.
I landed the craft - a P2A, by the way - then looked at the waypoint mission. As I expected, at every waypoint the cruising speed of 26mph was selected, and all the altitudes were as I'd selected. The area I was flying in wasn't a no-fly zone so that couldn't have triggered RTH. I'm totally mystified.
