RTH modes

[keat63]

Flying the MP1 manually through a wooded copse this afternoon.
Walking slowly behind it, and knowing that my RTH position was going to change, I'd already placed it in to dynamic RTH.

Only after the end of the flight, I'd realised that I never once got the message 'home point updated'
Checking the map, indeed showed that the home point was my original take off point 10-15 stroll minutes away.

So I googled it (as you do) and found that dynamic RTH only works in intelligent flight modes.

Looking at the two RTH options, one is the take off point, the other my location.
Am I undertanding this right.
Take off point will return to the take off point (obvious)
My location, will return the the place I was stood when I took off, so in effect probably the take off point less 3 feet.

How would I have the RTH to be the controller position.
The last thing I want to do is trek 10 minutes back in the direction I came in the event of an automated RTH (loss of controller error)

Not quite.
You have two choices to reset the homepoint.
During a flight, you can reset the homepoint stored in the drone.
You have two options:
1 Reset the homepoint to the current location of the drone
2 Reset the homepoint to the current location of the controller (this requires GPS location from your phone or tablet)

So in my situation flying manually, does a dynamic rth exist. ?

No
You have the two options I described above.
There is nothing that will continually update to follow you.

An oversight by DJI then.
I'd be well peeved had I needed to walk back. Imagine if in the mean time it was picked up by a passer by. Not good.

In your situation it’s probably best to set RTH (failsafe) to hover.
If signal from the controller is lost, and you are close (but tree etc might be blocking los), it will stay put and you can move closer and regain control.
If left for any sort of failsafe RTH in wooded areas, the obvious dangers of an ascent are too risky, but ok in a totally open area.
Always be ready to fly atti if gps is affected under a canopy and vps can’t function correctly.

Where did you get the idea that you could set the home point to be the current movable location of your controller?

 

[MAvic_South_Oz]

The word ‘dynamic’ I expect.
It’s only automatic in active tracking as per the manual >




But you can manually reset home position to controller location manually at any time (though painful via the menu).

If dynamic mode is available through intelligent flight modes, wouldn't it make sense that you could use this when flying manually.

No. Why should it?

 

[keat63]

Because if you lose control the the craft is going to rth half a mile away, rather than its last GPS position 15 meters away.

So, just update the HP as you go.

It WOULD be nice to be able to turn that on as an option if desired.
