    In-Flight Disconnect - Restarting Controller

    Today while flying my Phantom 4 Pro V2.0 on Litchi (doing panos), the aircraft suddenly disconnected mid-flight. Disconnected meaning lost video transmission and transmitter control. I attempted to open DJI GO 4 and saw that there was no connection either (figured). The aircraft hovered in place...

    P4P: In-Flight Power Failure

    I see. It was a relatively new aircraft - we only had 10 hours on that one. First time flying this particular aircraft on the project. It would be nice to have a coin cell battery or something continues to write to the DAT file for 10 more seconds after power-off/power loss. If the aircraft is...

    P4P: In-Flight Power Failure

    Thanks for pulling the data and analyzing it. What software are you using to get the display? Based on the analysis, are we able to come to the conclusion that this was a battery dislodge and was caused by pilot error? Or is it possible that the battery could have dislodged by itself and pilot...

    P4P: In-Flight Power Failure

    There's always the Phantom Rain Wetsuit: Home If battery dislodge is the actual root cause, would anyone be able to explain how the abnormal flight path of the P4P 4 seconds prior to the in-flight power failure links with the dislodge theory? There was no controller input when that occurred...

    P4P: In-Flight Power Failure

    Yeah, I heard about that too. Not sure that battery seating feature would have helped in this particular case.

    P4P: In-Flight Power Failure

    See, that's the thing - I am very well aware of that issue and make sure the batteries are fully seated prior to take-off (hard press in, check tabs). I had thought of this as a possibility (did not have a graph to reference) and even listed it as the first possibility in the write-up. ...but I...

    P4P: In-Flight Power Failure

    Thanks for the input. The surface we were launching from is responsible for the errors that you are seeing. After bringing the sUA away from the magnetic surface, the errors went away - as expected. The last minute of the data is what I am curious about. If you can provide any insight on that...

    P4P: In-Flight Power Failure

    I recently had a P4P fall out of the sky for no clear reason. One moment it was flying and the next moment the motor stopped and it was in the river. If anyone can take a look at the flight log and the preliminary report (attached) and then share some insight, that would be immensely helpful...
