I had an experience worth sharing with users that might lose their Spark for whatever reason. I was flying my spark in a new area using the RC connected to my Android phone using an OTG cable. I was about to take some photos from 200 ft elevation and a thousand fee away when I felt wind swirling around me and received a warning from the Spark about high wind and to fly with caution. I immediately started to return and almost simultaneously lost connection and I couldn't recover. I was sure the RTH function would work and that connection would be reestablished, but after a few minutes it was clear that Sparkie wasn't returning. I let fly with a few expression not be repeated and figured $500 was down the drain, then I remembered seeing the option to "Find My Drone" in the DJI GO 4 app. Sure enough, hit the menu option in the upper right hand corner and the last option listed is Find My Drone. In desparation, I hit that option and almost immediately saw the position of my drone and myself. I had do drive aways to get to the location and even though the two markers were superimposed on the screen I couldn't see the drone. Looking at the app again I see the option to request Sparkie to beep so I tried it and immediately heard the sound around the corner from my position. I was amazed and relieved to find the drone resting quietly on the bottom level of a children's slippery slide. The drone was still on and sending a position signal. I don't know why I lost connection, but I suspect the swirling wind included a severe downdraft and the drone was pushed down such that some heavy transmission wires were between me and the drone. I still think it should have returned to the home point, and can't explain why it didn't do so. However, I am very impressed with the "Find My Drone" application.

Last resort! thanks for sharing.

i am happy that this worked in lost connection , i am relay surprised about that. I thought that it will not work in such a situation .  And can you put here a log from this flight, meaybe we can see why it didint go in RTH

So glad to hear that you've found it. For the RTH issue, was the drone recorded the Home Point? Could you please refer to the link below to export the data for analysis? Upload them to the Dropbox, then provide me the link to download them.

soo... what were you taking pictures of near a children's slide ehh?... just kidding haha

Didn't know about the ability to have it beep, or flash the lights.  Again, something not in the manual that should be.  Great post!  

just thinking. if high wind will cause the spark to flip it 90 degrees from horizontal the internal sensors will instantly detect that it’s lost horizon and shut down?

Sorry, I tried to upload the data you requested, but I've flown the drone several times since the incident I described and the data had been over-written.

yes , you can that way in emergency turn off the motors if hand-held . But i was watching some videos on YT and guy with a leaf-blower tried to get spark to flip and it was a no-no. so i think its to nimble to flip from the gust of winds

Sorry to say that we may not be able to figure out what happened without the data.

HI Michael, so far, there is no "Find My Drone" on the built-in screen. Anyway, we'll forward the request to the engineers, hope they can take it into consideration.

Thank you for the heads up! I saw that feature and was wondering how it would work in a signal loss scenario.

I was wondering why so many people reporting fly aways etc or asking questions about attaching 3rd party tracking devices don't use this feature??

The exact same thing happened to me but I haven't been able to find my DJI Spark.
