Currently the way to stop the motors after landing is to hold the throttle all the way down for a few seconds. Is there a way to change this? It seems like a mistake could be made whilst desending to fast and hold the throttle all the way down causing the motors to stop while still airborne. I have read mentions on here about holding both sticks down and in to stop the motors. Is this just a secondary way to stop the motors or is it an option?
Thank you in advance.

DJI designers aren't that stupid.
Left stick down won't kill your motors in flight.
You can safely descend vertically at full speed from great heights.
The motors won't stop until the Phantom detects that it has stopped descending for 3 secs with the left stick hard down.

Are you sure? Today i was flying and brought it down to just over my head where I can reach it, let it hover for a second, and had my hand just under the skid as to catch it if it were to fall. I lowered the stick to zero and counted to three and it dropped into my hand.
So, as you say so arrogantly, maybe DJI designers are that stupid.
Also, I have read a couple crash reports from people who had there phantoms "drop out of the sky" and the report that they got back from their flight recorder showed them descending and holding the throttle all the way down for around three seconds, the motors stopped and it fell.
I will need a second opinion. Thank you for your help.

I've only done it a couple of hundred times.
And your question gets asked by excited new flyers every week  - it's not new.
Just a little searching will bring up many, many second opinions - all the same.
Left stick down is the normal method of descending.

And it's pretty naive to think that you've discovered something so critical that the designers didn't think of and that hasn't been discovered by thousands before you.
Come back again when you wonder what will happen when you fly from the top of a cliff.

Well if you were holding it then it would shut off as it senses no altitude change. That's how a lot of people hand catch their birds.
It is %100 safe to pull down on the throttle stick for as long as you want while in flight, it will not shut off motors.

He obviously is new to this and has concerns, Don't get offended when people don't take your word for it.
By the way it is not necessarily "left stick down". It is the throttle stick, as there are different stick modes!

You are welcome. The crashes you refer to are caused by people doing CSC, which I strongly recommend you go and read in the User manual so you don't do one inadvertently in mid flight, as it will shut off motors and your bird will fall from the sky.
Good luck

Geezus, someone didn't get enough hugs as a kid...or maybe you are just a little whinny kid.
I have been building and flying my own quads and hexacopters for a long time. Using many different types of flight controllers all with their own characteristics. So don't try to belittle me with your "look at me I know everything" attitude. I was just asking a simple question that I did research before asking and there were varying responses. I am not a little kid, learn some respect. Don't be an A@#HOLE. I guess the very first time you took your very first RC craft out to fly you already knew everythng there was to know and did not have to ask any questions? I didn't think so. So sit down. I did not ask you to answer my question, you choose to. Next time just go back a page and do not reply, I will do the same when you have an issue that you can not figure out.
Have a good day mate.

Hey there, my guess is if it was over your head and you held your hand up underneath the crafts sensors it may have sensed your head/hand as being ground zero and therefore shut down thinking it was at ground zero, just a thought. I have descended in sports mode from 120m to 10m with no problems at all.
Hope this helps.

It will not stop the motors until the sensors on the bottom of the Phantom detect the landing. Legitimate concern and it is covered.

hi,
he is not talking about CSC. he is talking about throttle fully down while in flight. Two separate animals altogether. CSC should only be used in an emergency and not the normal way to shut off motors once landed.

Let's just clarify. I wasn't saying that it had anything to do with CSC.
I was just putting it out there as  rayrokni mentioned about CSC,that the New way to CSC has changed in a recent update.

but we all have to remember that the way things are said, specially when you cant see the person, is just as important as the value of the content!

Landing is detected (as I understand it) by the barometric pressure and GPS, not the VPS sensors.  In fact, the VPS can be turned off.  If you reach up and hold the leg as it comes down, like some of us do, it detects that as a landing and will shut down.  Many land that way regularly, to keep it from going all the way to the ground, which may be too rough, or have tall grass, or water, etc., that is undesirable to land in.

you are absolutely correct, if it does not sense change in altitude then holding the throttle down for 3 secs will shut off motors. for example if it is hand caught or if it is caught on a branch at 50feet up!!

gary,

The new firmware changed the CSC for the P3 also. So, the Inspire 1, both the P4 and P3 are using the new method.

I could be wrong then in this case.... I have not risked trying this on my aircraft, as this is only for emergencies.

I may be mistaken, since I never use the csc,  but I believe it is only changed for the P4.    However,  I am still running f/w 1.4.0,  so maybe it covers the P3 as well if you have current firmware.

If DJI was going to make such a drastic change for the half-million or so P3s out there, somehow I think they might make a little effort to inform users.
And since they didn't, and only the P4 has any documentation to say it applies, and since several times DJI Ken has adviced that the new method doesn't apply to the P3 ...
I'm guessing that it doesn't apply to the P3.

I could of read a P4 thread about it an not a P3 thread.
It would be good to hear from a DJI rep as we need to know what to do just before we Crash {:4_142:}
