So having done this a few times, I planned a longer mission on Litchi 12kms out and back. It was an early morning flight, lots of fog and dew in the mountains.
About 8.5kms into the flight, the RC got disconnected. Before this due to continuous warnings of poor connection, I tried to stop the mission but could not (you can see a message in the video saying the same).
After the RC got disconnected, the usual setting in Litchi is that it continues the mission and it carries over to DJI.
But if the remaining distance is quite large, litchi will abort the mission and the ac returns home before the battery runs out. DJI however did no such thing. The ac went ahead with the entire 4 km out and back until finally I regained telemetry and brought it back just barely.
Now, the smart RTH was off in my DJI. Settings and none of the other RTH settings click in because in WP missions RTH triggers are typically overruled.
So after a nail biting turning to finger biting some minutes I had to land a km short in a landing area I use sometimes mainly to protect the battery pack (I could have flown back all the way but would have ended dangerously close to ruining the pack forever)
A few lessons learnt there, phew.
