Catastrophic crash tonight - Phantom 3 Pro destroyed!!

It's amusing when conservative users make up their own rules to make their flying even "safer" and often it has the opposite effect.
Using your wrench is not necessary at all and the anecdotal evidence you mention isn't very reliableif they used genuine P3 props with composite hubs.
Using the wrench puts too much pressure on the soft plastic threads and will weaken them prematurely.
They are only supplied to loosed stuck props after a crash - not for putting props on.
Do you fancy having a prop thread fail in flight because you've over-tightened?
Check the manual - DJI say tighten the props by HAND.
When you start the P3 you notice the motors rev up twice.
That is the P3 tightening the props itself.
Put your props on properly and they will not come off in flight.

You have convinced me! Thanks for debunking the misinformation! :cool:
 
......... Check the manual - DJI say tighten the props by HAND............
At first I was like, why does everyone say RTM?! Now I'm like......... I cannot believe the sheer number of new owners here that you just know haven't bothered to RTM!! You hear so many people say that's the last thing they do, and make a joke of it. But for the kind of expense for these things, it's simply beyond belief that they're actually not reading it, or just skimming over it. I don't get it. Oh! The box says ready to fly! :eek:
 
In the aviation world, more than 80% of the accidents and incidents are attributable to "human error". And we are talking of a system with strict regulations, procedures certifications , licenses, oversight......
Now guess how many Phantom accidents are human error when to begin with a significative number of pilots have not even bothered reading the Flight Manual.
Of course blaming DJI is fashionable and I am sure they have their own responsabilities on some of them, guess how many are simply human error.
Flying, with pilot onboared or not is a very demanding activity that forgives no mistakes.
And I just want to say I do not mean the accident related on this very post is human error. I am talking in general about the "Phantom world" :)
 
If you mean the video in this thread of my P3 going down...I actually found the prop that spun off on the roof of the neighbors house a few days ago, fully intact in new condition
I'd be curious, does the prop you found actually spin on to the motor in the direction it's supposed to? I know there are marking on the props indicating their direction to lock and unlock. Does the actual spin direction match what the particular color should be? Could it be mis-threaded?

Thanks for adding that. I, for one, did RTM cover to cover, in addition to exhaustive research, watching instructional videos, etc. That being said, I have no doubt that many do not. An expensive mistake as the owner, and potential risk to others (and fueling public perception towards the hobby in a negative manner). I think there is a lot to be learned through piloting these things, but putting everything into pre-flight safety, and checks shouldn't be overlooked.

A part of my first reaction on a failed motor spinning off a prop was "how is it that a prop would ever come off - why isn't there some sort of retainer mechanism to prevent it" (although it still would have went down). I know my situation is rare, and was unpreventable. It's mechanical, **** happens. I still feel like DJI needs to "dummy proof" the prop installation procedure - whether that is a prop that almost has a torque setting that just stops it from going on too tight, or some type of retaining mechanism, just reducing another potential point of failure or human error - especially for new pilots. Because as you said - not everyone is going to RTM. And even if they did, the prop tightening language is still a bit vague (as evidenced by the confusion of many).
 
Sorry to hear that!

The props counter the motor direction, so the motors actually tighten the props to the optimal tightness.

I dont take my props off. I dont like the fact that they are nylon threads, over time, the spinning on and off will cause wear... I only take them off to go into the back pack when hiking

Thanks for explaining that, I will take it as a compliment - branding me a conservative.
I happen to know a few things about threads but will heed your advice.
 
I am anxious to hear the followup re how DJI responds to you. I don't own a P3 yet, and am reading everything I can to learn all about them, then I will make an informed decision before laying down over $1000 for a quadcoptor.

Right now it is the best out there... I dont care what anyone says, DJI rushed to market with the P3. In 6 months it may be awesome, when all the bugs are out. I am sure I am one of the REALLY unlucky ones. And yes I am really annoyed that I am waiting so long, hopefully they replace Australia5s soon!

The P2 is a great quad but what i have experienced of a friends P3, it is much better...

Personally, I would wait another 3 months or so... GoPro may be a very big challenger to it!

That sounds like excellent advice. Thank you

That's a smart way to approach it. I did the same thing. It's early, but I personally don't feel like there is some widespread pattern of issues that should cause concern or reason to avoid the P3. I believe mine was fluke, and a rare mechanical issue that I, and most others, would be unlikely to encounter.

I already received my replacement (since I went through Amazon, I was able to deal with them, not have to go through DJI, at least while I was still under my Amazon return period). They were great to deal with, and I'd recommend going that route just for the awesome customer service (DJI could learn a lot on this front). Was a little anxious easing back into it with the new one, but no problems so far - and I don't anticipate any.

Despite what happened, I think the P3 is just awesome, and an incredibly stable platform, and a ton of fun to fly. I looked at the 3DR Solo, which had some great features, but was a lot more expensive unless you already own a GoPro 4, and as Stephan mentioned, GoPro is said to be coming out with one later this year or next year (a big threat for DJI). The main consideration for me was that from a stability standpoint, and which company has been doing this longer, developed more products, puts more into engineering, R&D, etc, DJI came out as a no brainer. I'm excited to see more competition. It's good for everyone in the hobby, as a consumer. But I'm not really interested in someone's Gen 1 product while they work out bugs at my expense. There is a certain element of risk with this hobby, that I am coming to terms with when you put one of these 400' in the sky. No guarantees, but the P3 seemed to be the safest bet. It is still early in the P3 lifecycle, but I just mean that DJI right now is the more mature company in the drone space. They really do need to tighten up their customer service though - especially with GoPro getting in this market - but thats another topic. Best of luck in whatever you decide!
 
The Active Braking System of the P3 makes it very important that you tighten down props more so than any other previous phantom, despite the fact that they are threaded in a counter rotational manner. With that, it's pretty disappointing that DJI decided to switch over to plastic threaded props over aluminum. Questionable decision form DJI

Not at all questionable! Its impossible to get everyone to apply the required torque every time to keep the props in place in an aluminum hub. But with NYLON it is far less an issue. If the threads are bottomed out its likely not going to fall off.
 
Combination Stick Command. The series of motor start/stop commands that can be entered to start or kill the motors. These combinations are supposed to be so unlikely in flight that they can't happen. Unfortunately, in reality, some can happen and cause a bird to drop from the sky.
That is true I would guess maybe the flyer held the 2 joy sticks inward @ 7 and 4 o'clock,and u would have too hold for 2 plus seconds.Who knows really feel bad for owner

I'm on day 3, maybe 6 flights in. My son and I wanted to take a short sunset flight tonights. All preflight checks, full battery, safe to fly, auto takeoff, go up to about 250' over my neighborhood, and the P3 suddenly starts violently spinning, controls unresponsive, makes a 250' plummet right in the middle of the street in front of our house, and its in about 100+ pieces. Completely destroyed. My kids and I retrieved most all of the parts. I wanted to cry. Now I'm just pissed. WTF happened? I wasn't doing anything crazy, and I am so careful and overly cautious. I located the Micro SD card...and there is a video file about 450MB...but it says that it is corrupt. How do I get flight data off of this thing to ensure DJI is buying me a new one?
Could you have possibly flown near power lines? If your UAV /controller transmission path gets interrupted by the encircling magnetic field, it's like shutting down your controller, mid-flight.
 
I didn't read everything, but from quick glancing, its obvious that you had a prop fly off. Getting anyone to accept financial responsibility for that is slim to none.

I'm not understanding your holding off a purchase based on this case, or really much of any case. This was 100% user error. How can DJI be expected to, or blamed for not, taking a loss for a users mistake? That doesn't make DJI a good company! It makes them destined to fail!! This was a simple, honest, user mistake! It happens to a lot of people! We don't fault Chevrolet for a car being side--swiped when it pulls out in front of traffic! Why would we expect DJI to do differently? Mistakes happen! Sometimes we take it in the shorts for them. Pick up the pieces and move on. Sometimes literally!

There was nothing user error about this. But, like you said, you didn't read the post.
 
I'm no DJI engineer, but I do know those props were on good and snug. The consensus was a rare ESC or motor failure that spun the prop off.
