Hi All,

I recently posted a tutorial on how the Spark's Return to Home feature works.   I think many of you may be a bit surprised at how exactly it works.  I thought I knew exactly how it worked prior to diving in to create the video and I learned a couple of new things in the process of creating the video.

I hope you find it useful!

If you are interested, check it out:




p.s. My apologies for the very end where my main camera had died for the last demonstration.  However, it is just rehashing what was described in more detail earlier in the video!

Oh, and of course this was recorded prior to today, so it doesn't include details of the new Dynamic Home Point that is being released with the new DJI Go 4 update and (I assume soon to be released) new firmware posted sometime after today.

Good info, I learned a thing or two. Couple things to consider. On the RTH settings, 500 meters is too high for US laws. 121 meters gets you as close to the altitude limit in the US as you can.
I thought the point of setting the RTH to the controller was so that the craft would return to the controller's location. I usually launch from my driveway or back deck and walk around my yard while I'm flying. I didn't realize the controllers location was not automatically updated.

It is not updated.  I performed a test in a local park where I set RTH to RC location, and then moved.  The drone returned to the location where I physically set home point, and not to my relocated position.

I think Dynamic Home Point is suppose to provide this functionality, but it's not out yet.

I don't think DJI has documented Dynamic Home Point officially yet for the Spark.   However, my understanding is that it was designed only for Gesture Mode and Active Track mode and it isn't dynamic for where the controller is, but is actually based upon where the AC is at the given time.  If the AC moves further than 15 meters away from its previous point, it marks its current location as the new dynamic home point.

They have documented it for ActiveTrack mode for the Mavic Pro.  Pg 19:  https://dl.djicdn.com/downloads/ ... ser+Manual+V1.8.pdf
