Anybody else got a better guess than mine, we need you data cruncher s...
It's not over until the Phantom is found.

I bought the drone at the beginning of March 2018 so I could not fly so much more than 2 weeks with the 

Is there any more information that may be relevant in the RC + model?

Sorry, the Flight Log is it.

Since the aircraft was in ATTI mode when it disconnected, it should have immediately started to land. That assumes, of course, that it lost uplink at the same time as downlink - if the uplink persisted then it would have delayed the autolanding.

However, if we assume simultaneous disconnect, then the descent from 70 m should have taken around 25 s. It was drifting at around 6 m/s, so if we assume it continued at that speed (it will actually have slowed down as it descended due to the wind profile), it would have travelled another 150 m or so before landing. Plotting that on the map shows the following:

I would start at the end of the yellow track line and then check closer (in case it did land immediately and drifted less due to the wind profile) and further (if the uplink lasted longer than the downlink - quite likely unless the OP switched off the RC).

Thanks for your calculations.

Looks like he was in trouble in less than 20 secs, I don't think he had a choice after that, so I not sure what you mean by ASAP.

"AS SOON AS POSSIBLE" Thank me later
