hello everyone.
I noticed a strange phenomenon today.
It was a very simple flight.
After the transition at 40m altitude, climb to altitude 60 to the next wp, and fly at 70m at the next wp.
After lowering to 60m in the last wp, back transition at 40m.
But the plane shows strange phenomena.
This causes very unstable elevation changes in certain sections.
I don’t know what causes this.
Judging that this may be a sign of stalling, I came here to ask you a question.
I attach my binary here.
I would appreciate it if you could let me know what could be the cause, or if there are any other issues you find, along with a simple solution.
