Will it return to home, land, or hover?

There was an option for this in DJI Go, but DJI Fly has very limited options and no such setting. Has anyone observed what happens, or can someone from DJI comment what it will do?

As of now, when RC signal is lost craft will hover for 11 seconds before returning home if you regain signal you can cancel.
There is no option at this time for hover or land , maybe with updates .

It happened to me two days ago where the Mini disconnected from the RC and I waited for a while and two options popped up to choose from 1- return to home 2- land. So I believe this what it does. I wish these options were in the settings to set before as the other Mavics.

You maybe right, but checking manual it only offers Rth , unless you were within 20m .

True. I did not expect to see at all. I will test it and possibly take a screenshot.

It's only the Failsafe that kicks in like someone said, in 11 seconds, and you could disable it whenever you regain connection.

I believe that if "GPS signal" is lost it will just land (I know, not what was meant). And if the IMU fails then probably a crash is soon.

If weak gps it will just land that’s correct, I think OP was talking about RC signal or Failsafe return to home

It’s happened to me a couple of times. Your description is the same as mine.
I’m usually 1250-1500 feet away. The is a lot of wifi near where I was shooting

Ok thanks all, so sounds like on RC signal loss it will return-to-home... and bonus info that on GPS loss it will land. Landing is the one I don't want, cause that's when it's most likely to crash itself, but if it's only GPS loss I assume I can regain control.

Hi brettt, there is no option for hovering or landing when the signal is lost for Mavic Mini, Failsafe RTH will be enabled automatically when the RC signal is lost for more than 11 seconds, and if the GPS signal becomes weak or unavailable during RTH, the drone will hover in place for a while and then start landing.

After gps lost it may well hover, but over 30 ft or so  (ie out of ground mapping ) it will go with what wind there is.
You'd have to 1 be able to see it clearly, and 2 be very quick to control it.

But if it has lost contact with the drine how will it know what you click for one of your 2 options?

If you lose the control signal, there are no options.
Page 13 of the manual tells you all you need to know:
Failsafe RTH
If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH automatically activates after the remote controller signal is lost for more than 11 seconds.

Flying any drone in airspace is a great responsibility, as a pilot the minimum you should do is read the AC instructions and understanding the legal boundaries you should operate in.

In most cases, what you lose is the live feed, not the connection, but sometimes you lose the connection and in this case, the drone will go back to the take-off point (assuming the compass is normal and there enough GPS satellites)

In the current software there is also an option for "Hover" when signal is lost.  How long would the mini hover before taking another action, i.e. how much time would you have to get closer to reconnect and regain control?

You have as long as it takes for the battery to go flat, that's it. It will eventually auto-land when the battery dies.

Would it know if it's flying above water so it won't "land" into the water?

Also, I don't see what the point is to hover or land if TX is lost. In what situations you would want it to hover until batteries die or land who knows where (TX is lost, no video feed), vs coming back home safely so you can regain TX or just return to you and land?

Me either: every time before take off I use to check this option to make sure RTH is set correctly. "Landing" is a very unsafe feature.
Use of "Hover" is the scenario when you decide to fly around a high rise building and can't set RTH altitude above its height for some reason.
Here is the discussion.

Do you know if the same failsafe mechanism kicks-in with the DJI Mini2?

Should be in the manual, guessing that it is something similar.

The mini has the same options. It is set to RTH by default.

It's in the safety settings. Leave it as RTH.
