Instead of pushing the two control sticks down and in, I always just hold throttle down to turn off motors once landed . . . .

I'm always completely freaked out when trying to descend quickly that my motors will turn off mid descent . . . lol, that's why I always descend with the throttle only half way (and yes it seems to take forever) . . . I always worry a quick miscalculation by the inspire will make it think its on the ground and shut the motors off if I'm full throttle descending . . . anyone else find themselves doing this?  or am I the only one on the wussy bus?

I share your concern however, I would be willing to bet that DJI has thought about that issue considering that they have thought of everything else. I would think that one of the sensors on the bottom of the Inspire would prevent that from happening. Consider the fact that it controls the evolution of lowering the  legs from a predetermined height from the landing surface.

It's bad practice (flying-wise) anyway to descend really fast - ie pulling your throttle stick all the way down. Unless you're flying a heli and doing 3D moves.
A friend of mine (using an APM FC) once switched his motors off when flying.. good thing he had good height and managed to restart his motors.

hello
for me this function (bringing the two sticks in the corners at the same time) is used for the certification Civil Aviation National
is considered a security feature, for example, if I am going to have a fly away, I can stop the engine immediately

Wouldn't anyone agree that a dedicated button that one needs to push and hold, (like RTH) would be a much better solution for shutting down the motors then having a small handful of guys accidently move the sticks to the no-no position crashing their 4k bird into whatever happens to be in the way?

Well, this point and CSC has already been discussed in another thread.
I'm a bit freaked, too when descending a little faster. It may be a bad practice (flying-wise) to descend fast, but anyway holding the throttle stick to down-position in mid flight should not cut off the motors. I'd definitely prefer a different way to shut down the motors (e.g. throttle stick full down and holding C1 or C2 for a couple of seconds).
I completely agree that it must be in some way possible to shut down the motors in mid flight in case of emergency. BUT it also should NOT be possible to do this accidentally by principle, indipendently if you are a beginner or expert pilot.

Compare this with a car. Bad practice or not, the engine should not shut down when you release the accelerator pedal.

It is my understanding that pulling the throttle down as far as it will go, will not shut the motors off in mid-air. The CSC however will, and that is even a requirement in some countries.

My common sense tells me the same (the simulator confirms it), but does it behave this way in real life?
Anybody can confirm this?  Or who has the guts to test it?

It wont shut of the motors ... But this manouver is not recommended any ways as you risk going in to "Vortex Ring State" (discussed in another thread in this forum) ...

Tested or guessed?

Tested ... Got alot of "wobble" from it !

Cool! Let's hope that DJI does not change that in future FW updates without warning!

I"ve pulled the throttle all the way down a few times and never had the engine shut off. However, I won't even touch the other stick when I do that out of the same fear we all have. Now, crazy question. If they do shut off mid air can you turn them back on doing the same thing? Who has the guts to test that one out?  I sure don't! lol
