Hello all
I need to know for sure what's the right way to set up the Mavic for safe indoors flight where there won't be GPS and its a commercial building which means lots of metal. I was told to go outside and calibrate compass and imu and that should do it, and it shouldnt drift. Please advise

Hope you have the care refresh and leave the imu alone unless prompted.

The space needs to be well-lit and the floor has to have a distinct pattern, so that OPTI mode can be achieved and maintained.  If you have that, then you should be OK.

Shouldn't the IMU keep it stable and not drift?

Throw a flashlight on the floor

It seems like a lot of indoor crashes I've heard about happen when the Mavic switches between GPS and ATTI mode, so try to keep that from happening. In practice that probably means avoiding windows or -- if you really want to be cautious -- disable GPS for the duration, which reportedly can be done by covering the rear of the aircraft (behind the battery) in aluminum foil.

In addition:

• Tripod mode will slow the Mavic down / dampen the effects of the controls and is probably a good choice if you can live with the reduced speed (2 MPH).
• Prop guards are good idea.
• As indicated in the above responses, make sure that VPS is enabled and that it has something it can lock onto.
  

Tripod mode is a good idea, however if you drift in and out of GPS you can switch quickly to regular mode and the speed differential can be a little tricky.

I wouldn't calibrate anything as others have stated (unless there's already an issue that needs to be corrected).  IMU can keep the craft fairly level, however though you don't have wind indoors you do have prop wash and you will get some drift.  The only way the Mavic can fight against a drift for you is if A) it has a consistent GPS lock, or if B) You have a lock with the vision sensors.  Bottom line is it needs a reference for where 'here' is.  You can create visual reference points on the floor if it's a fairly uniform floor surface, however that's easy if you want to just hover in a single place.  If you're moving around you will get some drift.  The good news is it's a finely balanced craft so it is controllable.

Personally I recommend prop guards just like DroneFlying does as cheap insurance.  Really cheap insurance.  Good luck!

Just make sure indoor is wide enough to fly and don't contain metal or things like that

I really appreciate the pointers

Prop Guards, Prop Guards and Prop Guards.

Small confined area will still cause the Mavic to drift, so just be alert.


The real best advice, don't fly indoors.

Well I think the answer is the Osmo for indoor shots. I wasn't sure how folks do it for real-estate type of shooting, but it seems as drones are only for outside shots

Osmo is a great tool for indoors , particularly using Z axis, flying AC indoors , you need to be in opti mode downward and forward sensors on , if the area is bright enough distinct pattern flooring and preferably a large space, turn of RTH or set to hover.
Good luck..

I fly in the garage in my condo building.I have no issues I have flown all around its a long garage.I turn off the RTH and it flys great.

Dear Chris,

Thank you for reaching out DJI Support.

You are not suggested to fly the drone indoors, the drone will drift and cannot stable. The space indoor is limited and the drone is easy to be effecte by radio interference and behave abnormally and go out of control.

Please fly in open area for safe.

If you have further questions, please contact us freely.

Sound advice...

You should look at the new propeller "cages" DJI just announced yesterday: lots of indoor flying is one of the few things that would make me seriously consider buying them.

It can be done I just wouldn't recommend it "if" you can keep from it. I did it once and although stable with no issues I wouldn't do it again. I'll use my Osmo to film inside for stable shots.

That being said, this is the only time I did it and the only reason I landed it was because it looked like the cat was getting ready to pounce on it so I brought it down.
