I need your feedback and help, yesterday I was flying my airplane with APM 2.0 I saw in OSD that it changed to Circle mode, that was probably because a low Tx or Rx low signal.
Since I noticed the mode change I move the switch and put in RTL mode. OSD show me that it was in RTL but later when the airplane was coming back it changed to circle mode itself. So I had to put in manual mode and flew it back to home as I could.
I did other test and it happened two or three times more.
Each time that switch to RTL mode meanwhile the airplane was coming back it change to circle mode alone.
This sound real strange for me because I understand that when you change to RTL mode it has not change the mode until you move the switch.
Could you please help me understanding why this could be happened, in this condition the RTL mode is not reliable.
