It's my understanding that if one pulls back both sticks down and center, this will shut down the Mavic Pro in flight.  Seems ridiculous to have such a feature on a 5 pound object that can fly. Is there a way to shut this feature off completely?  Maybe I missed something?

If you don't want to accidentally initiate a CSC mid-flight, then set this setting to "For use in emergencies only":

the ten thousand dollar question! How the hell does the AC know when there is an emergency? I mean really DJI! Can it hear an oncoming helicopter or paraglider and automatically do a CSC Maneuver on its on?

I think it bases it off the sensors and compass etc. If its not moving and sideways it tells the cpu its probsbly crashed and stuck so it auto shuts down the motors. Stuff like that

No. If you want to be able to do that manually, then you need to select "CSC Maneuver" instead. If you do that, keep in mind that the motors will always shut down mid-flight when the sticks are moved to the CSC position.

just got my Mavic 2 zoom, and because of connection issues, and weather, haven't got a chance to fly yet  Is this for real,  you can accidently shut it off 150' in the air?

well.... this is for emergency ONLY. As we know drone are pretty danger when flying up the air, either be it above the car or people (Sometime you may not want to due to safety purpose), i alway bare in mind how should i stop the motor in case of drop from the air... well this is only ment for emergency... if we were experince flyer, you couldn't be place your stick in either mode as mentioned on the above photos.

you can shut it down intensionally, I have not heard of anyone accidentally shutting it off.

Yes, it's for real. See post #2 above if you don't want it to happen to you.

It's not both down and center, it's both down and corners. Known as CSC. It can shut down the motors in flight  but it can also be used to restart the motors if you know what has happened. (there is a video somewhere on this forum) Best of luck with that one!

There is 1 post that I know of where the guy posted his drone crashed for no reason.......

His flight logged showed he shut down the motors by initiating a CSC stick move and held it long enough to shut her down.......sad

The goddamn contriller beeps for everything else why can’t it start beeping before shutting down motor?

That's really not a bad idea.  It should at least beep with very little delay if your sticks get to the CSC position.  That would give you a few seconds to wake up to the stupid move you're attempting that would cause a shutdown/crash.

CSC is a good thing to have on those very rare times when it may save someone from injury or even death.  But, it really should be a dedicated control that can't be accidentally activated.

personally is should be a steady screech at full volume... everything else beeps.. the screech would warn you that you are being terminally stupid...

The biggest need for CSC is public safety if you craft was to plunge come down on persons fly into someone on take off, we have seen this in a video in England where a baby in a stroller came into contact with a phantom 3.
Now certainly for me I would think it absolutely ridiculous that I would get a warning of some beeping or screeching before it was to late to switch off motors, CSC is for emergency with beeping first it will most likely be to late.
There are two settings for this probably the safest one is in emergency if there is contact motors will immediately switch off, in my view the safest , I also think they should change Mavic CSC to RTH button and left or right stick down to corner as they have on phantoms.

Perhaps you misunderstood what I meant.  As you know, there is a delay when you apply CSC before it actually takes effect.  I would propose that the instant both sticks went CSC it beeped in realtime to alert you that you've gotten to that point.  That would give you time to release the sticks before the delay time times out and shuts things down (for those doing "stupid" stunts that would accidentally create a CSC moment).  If it really is an emergency, of course you just continue to hold through the delay (ignoring the beep) so it shuts down.

bingo......

whats too late is if you have your sticks in that position for a CSC during normal shooting not realizing it until the bird goes down...

I think one should try it , it certainly is not normal shooting unless your digging a hole lol , safest way is to use second option so this cannot occur, put it in your preflight.

Question comes to mind...
Is there anytime a person would really want motors to completely shutdown in mid-flight?

If drone is about to crash into something, it would be best if pilot continued to try to minimize impact vs. killing props and letting drone hit at speed.

If say drone and helicopter were on intersect course, it would be best if pilot tried to change direction and altitude.  Full descent command would initiate faster then going through CSC.  With result being nearly same downward velocity as if props had been fully stopped.  While giving pilot ability to slow descent before impacting ground or even save drone from impacting by commanding for ascent.


Time it seems benificial to have motors completely shutdown with a CSC is after an emergency (drone has detected impact, an emergency).

I have seen a bird to two thrashing around on the ground (not DJI in this case) where the pilot was fumbling around trying to 'fix it' where shutting down would have caused less damage.. but in general I agree that purposely cutting off engines kinda limits your options ...

think is.. not everyone that buys a drone .. at any price point .. is guaranteed to have 'experiance'  and accidentally putting the sticks into cutoff is a possibility..

and while the mavic has a setting to make it 'emergency only' which supposedly keeps you from using it unless the FC thinks there is a reason.. the spark it can't be turned off to my knowledge...

and while I will likely never do it on purpose other than to start motors to take off manually, I can't say my 8yo while flying it isn't going to put the sticks in a 'dumb' position

that said.. there are crazies that like to shut motors down and (try) to start them up again etc.. and for the crowd that wants to leave the ability to have near instant cutoff of CSC at a whim.. a little warning first isn't much overhead to plan in for safety sake with a little noise or shake coming from the controller ..

my 2 cents

Agree with sound and/or shaker.  

Maybe have Joysticks deliver an electrical shock, if motors are killed in mid-flight?
