Hi there,

I have found very little documentation on what happens if my plane is flying in mission mode and loses data link or RC link with the data link and RC link failsafes disabled. Would the plane continue flying the mission?

Also, when I used the Return mode failsafe in the past for data link loss and RC loss, the plane flew straight and didn’t attempt to go to the mission landing point. Any suggestions?

Thanks in advance!
