I think DJI needs to fix this massive problem, when you are flying and relaxing watching your phantom then all of the sudden you see your battery is low so you decide to get down fast or you need to go pee or whatever and you want to bring the phantom down fast, you go and pull the left stick down all the way to decent and before you know it after two seconds of full down it goes down like a rock and crashes into pieces.

DJI needs to route the kill motors function from the CSC and the full left stick down to the back buttons on the controller or a different less used combo than this, as i tested both possibilites and it killed my freaking motors mid AIR !!!

SO if you are going down and need to go down fast, DO NOT GO FULL DOWN, increase your EXPO on throttle like i did and make sure you don't pull down all the way more than ONE second.


To clarify : this is just a specualtion and it happend in a controlled location, no phantoms were harmed in this controlled test.

I use full down all the time Willie. Did a little while ago as a matter of fact. No premature disarming for me.  Maybe you have an issue with yours? That's puzzling!

Now if I hold the p3 in the air (hand catch) and then do full down it will stop it as it senses that it is not falling anymore and assumes that I want it to disarm. If you are having barometer problems I could forsee this happening however.

Thank you for clarifying it as i am always sketchy when pulling that stick down, having nightmare of it just falling down as i was testing all stick combinations that would cause killing the motors in my HAND.

I hope it does not rely on the barometer and only rely on the gyroscope.

willie i am the first to say CSC is an absolute engineering bolloxed up!!, but i use throttle full down all the time to descend and it has never cutt off motors!!!
i dont know what the problem may have been but that has not happened on mine!!!

Just a theory...

Have you heard anything about some of the reported barometer issues that some are saying has been corrected with the recent firmware update?

I wonder if your Phantom was experiencing this error, it believed it was not descending and killed the motors?  

I have actually feared that this would happen.

Were you able to update the firmware before this happened?

Were you anywhere near the take off elevation when this occurred?

Hang it out if ya gotta!! LOL. I am amazed at how much faster this descends than my other model. It is kinda scary it's so fast. They slowed the old p2's down in a fw upgrade way back. Not the p3 though! As I said earlier. The down stick shouldn't get you on that.

The barometer issues were just inaccurate. I don't think any failed to report a decrease in altitude, just wrong altitude. I wouldn't think anyone should have lost a bird from that.

So there was consistency to the inaccuracies?  Like as in the barometer was still consistently fluctuating and never freezing or level?  I honestly don't know because I was lucky not to have those issues.

Mr. licensed troll do you feel better after attacking other people? does it make you a better person? please if you don't have something to contribute then please go on your marry freaking way and bother someone on the street or even better go give a heart attack to one of your imaginary airplane passengers.

he very well may have, as i did on 2nd day of having received the p3, due to not having read the manual about the most stupid engineering flay, CSC, the same controls that is used to fly!!, i suppose a kill button under a flap just wouldnt have made sense, right?
so lets say he did do that, so now you gotta drive the nail in and gloat over someone else's misfortune?

Either way, I obviously disagree that this is a pilot error and your most recent response seems to validate that you have rethought that?  Or is there some unspoken rivalry between you and Willie Wonka I have missed here?

Do you know what kind of rivalry I am talking of?  I get it with some of my good friends, exploiting any opportunity to take a jab at the other.

Haven't rethought anything, still sounds like pilot error to me. And no I don't know Willy Wonka from Harry Potter.
As a licensed pilot, when I make a mistake (and live!) I evaluate what I did so I can learn from it (but I don't blame the airplane). All I'm saying is let us stop being so quick to blame DJI for everything.

That wasn't an answer it was an opinionated statement created for the sole purpose of stirring the pot.  That is why you are being described as a "troll."  "Troll" as it is used in online forums and social media is not name calling, it is a short hand description based off of trolling for fish to catch them.  You are simply "trolling" for responses and to stir things up.  

I give you credit, you have been successful in your attempt.  If this is what you need to get off, you may now be excused, just don't come back until after you have washed your hands lol.

But seriously people, dont you guys think there is a better way to kill motors instead of using flight controls?
this is happening way too often, agreed, IT IS USERS FAULT FOR NOT READING MANUAL. IT ABSOLUTELY IS NOT THE FAULT OF DJI.
I am just saying that there must be a better way, imagine if you could kill your car's engine whith the steering wheel, well i suppose you could, by STEERING IT IN TO A TREE!!

Don't put words in my mouth.  Being a "licensed pilot" does not excuse you from ignorance.  I know first hand and I know 2 licensed pilots, one in which was also a mechanic, flew in Vietnam, flew helis, Cessna, Beechcraft, and is now dead...  

I actually know/knew more licensed pilots that have died in plane crashes than those killed in or around automobiles.  You can validate my claim too with FAA records.  My best friend's Dad died in a plane I had been in on numerous occasions (Warner Springs, CA), one that I would have been in at the time of his crash if I had not gone snowboarding that day.  Within 30 days of that incident, my former baseball coach and his son, went down in the Rockies on a clear day with light winds in a twin engine plane.  They waited an extra day for good weather and were still adversely effected by it.  Both incidents ironically occurred just weeks before Sully landed in the Hudson.  (January 15th, 2009)

I also know a good pilot practices humility.  Not running around every forum on the www to brag about being one.  In my opinion, you have something to prove for a lack of something else and I'd be willing to bet I am not the only one here with that theory.  I would be rightfully nervous to share the skies with you and have already had more than one encounter with a "know it all" in the air that feels like they are above the common courtesy of communicating with air traffic control above a runway, or to learn the English language well enough to fly in an English based airspace.

No, this is not working like that. If it was so, a small mistake of barometer could cause the switch off of the motors.
In those 2 seconds P3 checks whether the altitude is decreasing. If its decreasing, it doesn't switch off the motors. If it's constant, it switches them off.

"From Wikipedia, the free encyclopedia


Jump to: navigation, search


"Trolling" redirects here. For other uses, see Troll (disambiguation).

"lease do not feed the troll" redirects here. It is not to be confused with Wikipedialease do not bite the newcomers.

In Internet slang, a troll (/ˈtroʊl/, /ˈtrɒl/) is a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory,[1] extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the deliberate intent of provoking readers into an emotional response[2] or of otherwise disrupting normal on-topic discussion.[3]

This sense of the word troll and its associated verb trolling are associated with Internet discourse, but have been used more widely. Media attention in recent years has equated trolling with online harassment. For example, mass media has used troll to describe "a person who defaces Internet tribute sites with the aim of causing grief to families."[4][5] In addition, depictions of trolling have been included in popular fictional works such as the HBO television program The Newsroom, in which a main character encounters harassing individuals online and tries to infiltrate their circles by posting negative sexual comments himself.[6][7]"

Again, nice try
