I was flying my P4P using a mission that I have flown 7 or 8 times. This time it crashed into the tree tops. I was able to retrieve it and the video showed it crashing into a large branch. (see pic). I don't know what changed? The last time I flew the mission was Nov 8, 2020. I live in Pwnnsylvania and do not believe the trees grew that much in that time. The only thing I can think of is that the leaves on the trees allowed the bird to "see them" and avoid them. What I plan to do next is take-off from my usual spot and walk the few hundred yards to the tallest tree and see how tall it is with the bird and then check against the mission specifications. Any other ideas will be appreciated.
