Let me tell you about my experience with my New Mavic Pro.  I took it to work with me and wanted to fly on my Lunch break.  I fired up the Mavic in the Parking lot, did my compass calibration, and was ready to fly.

I launched and everything was great.  I flew around and then, I went into Tripod mode.  It did exactly what is was supposed to do.  It slowed way down, and then I had the great Idea of going into the shop and show the folks I work with.  I was very cool, I made it through the door and was hovering when I got a Lost Connection signal.

This is where the fun started.  The settings for Return to Home is set at 30 meters, the ceiling in the store is 12 ft.  Well you can guess what happend next.  Yes it switched to Return to Home and tried to rise to the correct elevation and flew right into the ceiling.  It tried several times before one of the props broke and then did a Right turn and went out the open door!

It tried a climb and then did a dive into the ground.  The Motors were still trying to climb and in a panic I reached down and tried to grab it.  Big mistake!  The props and still turning at a high rate of speed and came into contact with my finger.  OUCH!  Well I finally got the motors to turn off, and checked out my NEW Mavic.  All four Props were broken.  

It was the only damage I could see.  I replaced the props, fired it back up and its works great.  I did a bit of flying to check it out and other than my finger hurting like hell, all is OK.

I reset the RTH function to HOVER.

Lessons learned the Hard way.

Thanks, good story and lesson. I'm glad that you only wound up with broken propellers and injured fingers: props are cheap and fingers heal, but neither is true of the Mavic's gimbal which has a poor record of surviving crashes.

remember to take off hover for RTH when out side

It is always better to learn from some one else mistakes and it is cheaper but... Also, before switching to a different fly mode adjust all of your setting and always remeber that you always might use GPS connection so always be in LOS and prepared to take in ATTI...

Leave RTH on, but next time, take off indoors and you won't have a RTH homepoint set negating the issue.

It was the RTH Height settings that caused the challenge.  I have recently flew indoors filming a Veterans Honor Ride.  

Thanks for the feedback.  Still learning the do's and Don't of this Drone

I'm not so sure that's the safest or most reliable procedure for indoor flying. There's always a chance that the Mavic will gain a GPS lock at some point in the flight, and I believe it will immediately set a Home Point if it does.

I think the better option is still to set the Signal Lost option to Hover.

It must still have had some GPS reception or otherwise it would have done hover instead of trying RTH.
So the transition into buildings is the dangerous phase i guess, once it lost GPS it should behave.

Greetings,

I am pretty sure the homepoint is set before take off only.  The only way to get a homepoint after takeoff is by manually setting one in flight.  This is for obvious reasons that you may take off outdoors without a GPS signal for some reason and you don't want your homepoint being set 1 mile away when it finally gets a GPS lock.

I'm afraid that's not the case. Here's a recent example: http://mavicpilots.com/threads/r ... avic-is-lost.14656/

The owner took off in ATTI mode (surrounded by tall buildings) and the logs show the Mavic set a Home Point 49 seconds into the flight, while at an altitude of 29.5m.

Wow.  Yes, that is not proper programming.  I am going to try that and take off before the home point is set.
