I had an interesting flight with my P4 under Litchi on Wednesday, from the top of a hill, out over a lake to a point on the other side, and then return.
Most distance point was 4.049 kilometres away, and the total flight was 8,175 metres.
The thing I don’t understand was why, at 7:49 mins and on the way back at 3,109 metres out, and with 62% battery, the P4 initiated RTH.
On the way back, cruising at 45 km/h , with only about 3/8th of the mission to complete and heading for home with 62% battery left, it seemed in no danger of not making it back, so why would it initiate RTH?
After that happened it had to climb from -148 metres, to + 108 metres to reach the RTH height, and stopped to do this, right over the middle of the lake. I eventually kicked it up to 35 km/h to get it moving again, and it eventually landed with 35% battery left, a very comfortable position.
