In theory yes it can, in practice it depends on what lies between the drone and the controller and also what the drone lands on and or lands IN.
Lets start with the simple stuff, if you can get it to land, stop the motors and still have signal, then you may NOT be able to restart the motors if the drone is at too great an angle of tilt.
Similarily vegetation etc. that was of no consequence in the landing may be stiff enough or intrusive enough to prevent the motors from starting.
That is not a joke, grass blades could get into a motor and jam it, grass stems or shrubbery that was blown out of the way by the down draught from running props during the landing may spring back when the motors are stopped etc. and prevent the motors from restarting.
And that's not even considering what vegitation etc. would do the camera and gimbal.
How do you get it to land in the first place?
A manually commanded landing, caused by holding the throttle closed, is the obvious way to do it, but once the drone gets below 50cm above the ground ( AGL ) there is a semi or completely automatic procedure that tales over.
It can be over ridden providing you still have a connection but I have NO IDEA what will happen if you lost connection in those final 50cm. It may continue to land in which case you are "up the creek" or it may trigger the failsafe behaviour. But I do not know what it will do with regards to failsafe behaviour in those unusual cirucnstances.
As an alternative to the manually controlled landing, there is a "land" button on the screen of a normal phone running the Go4 app, so I assume the
smart controller has one too.
If you choose to land the drone via that method then I have no idea whether or not a disconnection at ANY AGL will cause the failsafe behaviour to override the previously issued land instruction.
If failsafe does override the land instruction then what happens depends on what failsafe option is chosen. There are three options.
a) RTH, the explanation of which is fairly obvious, but read up on the actual faisafe RTH it is quite complicated and time consuming.
b) Hover, which again seems obvious but may/will end up in a low battery RTH if the connection is not reestablished.
c) Land, which agains seem obvious but the drone may judge the ground unsuitable for a landing and abort the landing, in which case it will hover and that in turn may end up as a low battery RTH.
Would I try it where the proposed landing site was distant and or inaccessible? NO.
Have I done it, yes in my back garden 15 to 20 ft away from where I was stood.
As a newbie would I try it, NOT A CHANCE.
