Hi DJI!
Are seriously i sell this st???
This drone fly 50x and engine umpliged in landing time???
Drone in landing start vybrating, rotating arround self.
Noboby know what happend and i didn land derfore.
In last seccond i cacted dron under body and engine flyed out. I sent today this drone to germany servise.
Please check and inspect to device what happend in this expensive st!!!
Dron , camera, everting is not damaged, bezause i catchet to my hand. Engine foleddown to snow.

I was injured by a loose engine.

Im very ungry and with concern about safety this drone !!!
No scrues in arms ??? Wtf ??? Only glue???

Come on!!!
10 000€ drone and only glue???


Hight speed drone 100km/h and only glue ???
U kidding me?

I invest mutch money for dji accesoriess and droness also and i got this st what hurt me? What did u say when will stay near me little child and hurt him???

Please, give mi true response, if not, i will take blakbox data also detail inspect photo to airline inspection

fansdfe3e97a, Wow that is BAD! I am sorry that you got hurt that is terrible. I hope you get well soon and get things right with DJI. I recall seeing another post a few months ago about that EXACT problem, Broken Glue On Arm. Best of luck sir! Safety First! Ken.

Thanks, hand will be ok i hope :-D but im so wery bad for the drone, for construction. Im waiting for answer from dji

No - the Glue is DEFINITLY strong enough not to cause the vibrating motors from the loose props to vibrate their selves loose and cut you ribbons.

Jokers..

Whoa!!!! too much info on the fingers.

Jop :-D i have fly record, this is like evidence...
Glue is strong ???
Watch the picture...
Arm is not broken, engine is unpluged. If you like see something. Take to google abou the arm inspire 2. Im not first. Also many people on social network responded me, that had some experience ...
I like so mutch my inspire 2, but is usafety because, only glue hold the angine on arm ???
Aircraft was in the service, report say, glue hat air boubles around contact with plastic cover.
Definitely i didn say something wrong. Only true.
Best regard

Hi, sir. Really sorry about the accident. Please take a good care of your hand and go to hospital as soon as possible. Did you contact our support and open a case? Please tell me your case number so we can follow the case for you.

Thanks, i was in hospital. My finger has little reconstruction.
I hope it will be fine :-)
Dji inspire 2 is on way to germany service.
I would like ask u, will be soon any update for the issue? Im worry about safety.
Because dron not foleddown only motor was unpluged from arm :-/
Therefore im hurt, engine flew out and hurt me.
I hope that will by soon in germany service and i will write case number.
In monday ill contact customer center to my dealer dji and ill require case number.
Thanks

I also wish you well soon.

Just to clarify. The motor detached from the boom arm when you caught the drone by the landing gear. The motor came out without any impact to anything. If this is the case, this is a serious  issue.

I think the glue is factory stress tested under normal prop rotation and vibration when new, with props that don't rattle.

Add in loose props and the vibrations caused are simply too much for the glue to hold.

Why don't DJI just fix this by giving us new props that fit and don't cause such vibrations?

Many of us are nearing or at the end of our warranty period. The glue isn't going to get stronger with age.

Every time the I2 flies with loose props or has a slightly hard landing its putting strain on the connection between the arm and motor.

Not cool..

Absolutly true!
I think, that I2 not testet on diametral situation. Enginers muts think about temperature, material oxidation, abrasion, microfracting material and glue. I think that will be mutch accident with this issue!
Im lost trust the dji inspire 2!
Why? For a factory issue and safing money for construction van i had accident. Thats unnormal i catched drone and motor with prop flew out. What will be do DJI company, if i lost eye or was more hurt my hand? I payd for dji inspire 2 and accesories for i2 20 000€!!!
For this money i can buy good car!
If will cost 1000€ i2 o will nit think about and i wil put the trush!

I ask u DJI, why u sell unstable drone, higest quality! To customers and u know, that drones has defect in development and u know about that can hurt somebody? Or child?
If i lost the engine, drone is unstable and very danger!!!

Hu will pay all medicament and rehabilitation from this accident?

Dji dont try say that was accident from wrong fly!!! Its uncapteptable.
My finger will recare 1-2 monts, rehabilitation. For your failure!

I spoke with my loyer about, this situation. Im waiting that somebody will call me and will speak about the situation. If not, i will take the else inspires to inspection in airolines.

Im not requering sadisfaction about the accident also any money, but i want any progress in this situatinon.
U have my contact. O possible, somebody can call me and inform me what will we do...

I have uav licens, 7years experiense in flying.
Do not forget it, that we are also soecialist abou the problematic to drones.

Best regard!

Best luck on healing.  Injury looks like a lifetime of remembrance.

I've noticed the Inspire 1 has a lot more screws at joints holding it together than the Inspire 2 does which is mostly glued together.  Legs are more stout too on the Inspire 1.  There have been videos of the I2 where the motor comes off in flight and it falls.  If the carbon fiber is not prepped and glued right with the right glue no doubt the joints will fail.  DJI has been marketing the wrong Loctite for drones for some time as it will craze and crack plastic.  I had one motorcycle windshield crack in half on the freeway and inspection around the mounting holes showed the crazing of the clear plastic due to out-gassing of Loctite from the mounting bolts which were covered in the blue Loctite.  Loctite warns about it in their datasheet and to use the correct one made for plastic, but DJI doesn't use the correct one.  Could be their glue for carbon fiber is also wrong.

There is someone who was making a stronger coupler (3D printing which I wouldn't trust.) for the motors on some other forum that bolted on.  Another used some Pop-Rivets to hold them on as a backup.  Those are possibilities, even though it might be a low percentage of failure.

Good luck.

Dear DJI, why u sell grips if is not safe???
Nobody answer my questions
https://youtu.be/ECy75GyzNvc
This is your video where pilot cathing to grips the drone. I did also.
But engine flew out.

Please u dont say that i must turn off the motors and after i can hold the drone in grips. Eatch your promotion video.

Please, what i can do?
Im so very hurt and everyday i feal paralised becauce i cant use my hand :-/

Nobody interest this situation in your company? I writed on technical support, facebook, email, i tried writing on online support.
And what? Nothing.

Ist because i spended lot of money and right now nobody interest the issue on the device?
On facebook contacted me 121 people with identic issue, Diferent company make accesoriess for fixing this issue with the glue.

I payd 20 000€ for drone, that i will find another company who fix your issue?

Do you like buy the car and after in warranty u must fix yourself?

Come on!!!

Hi, Marek. Thanks for your update. Please reply my PM and provide me the SN of your drone. We will have someone follow your case. Please wait patiently. Any problem, please inform us.

I would like to know if DJI approve of aftermarket solutions for this problem, such as the below item:
http://dronedepot.co.nz/inspire- ... e-2-feet-clamp.html

If they do not, can DJI please advise on the correct procedure to prevent this problem.

Here is another video which appears to show the motor mount coming loose from the boom in flight:


This is very concerning.

Hi, Doble. Thanks for your attention. Please note that the situation is forwarded to our engineers. They are looking into the case and I believe they will deal with it.

I am watching this thread with interest.
There have been several reported incidences of the motor-mount failing but this is the first that I am aware of which involved a serious injury.
I personally campaigned over a period of several months regarding the loose, ill-fitting propellers (see  https://forum.dji.com/thread-100223-1-1.html) and while I can not prove that this is the cause of this accident it is a reasonable assumption that the vibration produced by the loose propellers could stress the bond between the motor mount and the carbon-fibre boom and over a period of time could result in a failure of this nature.
I do most sincerely hope that that DJI will now finally start to listen and take steps to correct the problems with the Inspire-2.
Kind regards
Allan Arthurs

U think this? 3x motor was noise and rattle same like this.
I had the noise like 2-3 monts. I didnt find any solution. Only reseler talk me that i will try change the props

There are various suggested solutions, including shims of different kinds and replacement propellers - none of which have been approved by DJI.
However DJI have offered no solution themselves. The only response from DJI up to now has been that this is due to manufacturing tolerances (which is perfectly obvious!) and is perfectly normal.
While it may well be normal in the case of the Inspire-2 - it is certainly NOT acceptable.
Any aircraft engineer will confirm that no amount of free play is acceptable in any propeller mount..

Kind regards
Allan

Hmmm, im very exited how will over this case. Im very bad hurt, every day i feal like invalid man ...
Im using 4 medicament for taking down the hurt feal, my temperature, because on one finger i got infection... everyday i must go to hospital to cleaning to hand. For somedody who not watch the work ...
Dji can try how i feal ... take finger to props... im very sad, but i hope that somebody from dji eill fix problem for all of us...

I've been an aircraft owner/operator also for going on 20 years now. And if there's any Golden Rule that must be followed else death can occur on anything with a prop on it is a prop must NOT be loose. It must be firmly attached to the prop flange, bolts torqued to the correct value and there must be NO play or movement at all. In fact, nothing on an airplane should move except the control surfaces.

It should be noted that a loose prop can tear up even the strongest, most well designed motor mount, so even if the Inspire 2 mount and boom is sufficiently strong, once that prop starts running away it can and will tear up everything the motor is attached to.

I agree that this is a major safety issue with the I2. The foam-in-the-hub fix, BTW, isn't a proper fix. That prop hub has to be securely mounted to the motor.... This really needs to be redesigned, those two little clips aren't sufficient, in my view.

Something like the P4 and mavic pro spring-loaded mounting systems, or a permanantly attached folding prop.

Honestly, I wouldn't fly an I2 anywhere near persons or property with those props/hubs in their condition. Just too dangerous....

I am very sorry for your accident and injury to your hand. It is difficult to determine what happened after reading your information posted. I would like to say based on your flight records you have much experience flying drones and by now you must be aware that they can be dangerous. 15" props spinning with great power should always be managed safely.
If you really look at the videos that DJI produced, they had  dedicated aircraft handlers with safety equipment on them. See screen shot below.

I think that DJI should help us understand why the motor pods can fail at the glue joint,,, is this random? Is there something the pilots can do to avoid the stresses that cause these failures?

Again I am very sorry for injuries and wish you get well soon.
Rich

I was thinking about this some more after my first post.  the centrifugal force on each motor is dependent on proper balance of the propellers. This force could easily over stress the motor mounts. I have seen this happen on full size aircraft the propeller goes out of balance and can break the crankshaft right off the motor.

I saw this happen at the Reno air races right in front of me. The pilot made an emergency landing and was safe, but pretty scary.

Rich

This is a known design flaw with the DJI Inspire 2. There have been more reports of this exact failure on social media than I care to count.

DJI have known about this since at least March 2017 when a friend of mine reported it. Why has nothing been done about it DJI Elektra? Why won't DJI issue a statement to address it's customers concerns?

Now your defective product has caused a serious injury and it is only a matter of time before this happens over a crowd, the force of an Inspire 2 in free fall from a few hundred feet could easily kill someone.

You need to come forward and address this issue instead of trying to keep it under wraps, peoples safety is at risk!

I would say with the present situation about flight data going back to China DJI needs to be very careful with this glue failure issue.  One more bad thing will get them banned in the USA and so then so goes the world.  A recall can be expensive but so can the loss of sales or liability lawsuits.  Ive been flying the Inspire series since each one came out and now I'm beginning to lose confidence in the aircraft with reports like this.  This is going to keep Mr Schulman very busy.

https://forum.dji.com/thread-88986-3-1.html

If you read from post 92 there is an example of some 3D printed shims to hold the motors in place.

I had some made in the UK months ago for around £175 and attached them two days ago after reading this post.

I placed some M3 double sided tape on the arms and motors to ensure a robust hold.

I've been through five sets of batteries in the past two days and so far so good. I'm confident that they are more than enough to keep the arms becoming loose.

The plastic used by the printers is used for aviation and motorsport parts so should be more than strong enough.

I realise that many people wont want to spend the money, time and effort in adding this extra protection but I feel much more confident flying now. They even look cool!

I would be interested to know if there have been any reports of the motors coming loose from the arms when using another type of prop rather than the loose DJI standard? My guess is not, I'm 99% sure that this is happening because of the vibrations caused by the standard props and could be fixed fairly cheaply by supplying ones that fit. Much cheaper than a possible product recall after someone else gets hurt?

If you read from post 92 there is an example of some 3D printed shims to hold the motors in place.

Reading the comments on the facebook thread about this incident (DJI Inspire 2 Owners Group) it's clear that DJI's customers have had enough and they are demanding DJI address this issue and provide a solution. We shouldn't have to purchase aftermarket parts to fix their design flaw.

UAV are considered aircraft in my country. If any full size aircraft had just one failure like we are seeing on the i2 there would be an Airworthyness Directive issued and any other aircraft of that make and model would be grounded until the issue was investigated. This will happen with UAV and this issue could be the catalyst for that.

The I2 is an unsafe design because the blades vibrate significantly in flight due to free play at the blade mount.  
This vibration then causes structural failures elsewhere ... e.g. the motor mounts.
DJI are blind to the problem ... they continue to state that the blade design is perfectly safe ...

I've stopped flying my I2 in fear of an in-flight failure of the motor/prop/mount. I just have zero confidence in the drone. It makes me sick to the stomach that I have this machine that I have invested my hard earned money and I can't fly it through fear of an issue.

I have emailed DJI support and argued with them that these loose props are dangerous and all I get back is that DJI consider it to be a non-issue. They've told me to try another set of props. Well both sets included with the aircraft are loose.

After not leaving it alone and continuing to email they've told me that they'll send me a coupon for a new set of props. I'm not interested in that because that isn't the fix!!

I'm afraid it is going to take a very serious accident in a country like the USA before this company from China is going to stand up and accept that the I2 has this serious design flaw.

It's going to get worse before it gets better

It would seem DJI believes its responsible for the aircraft only during the warranty period.  This maybe true for replacement and repair but corporate responsibility for injury remains long after the warranty period expires especially with known defects.  Car companies are liable for manufacturing defects throughout the life of the vehicle especially involving safety equipment.  Just because I check the motor mounts before flight doesn't mean the glue joint won't fail five to ten minutes later as temperature changes loosen the glue grip and vibrations cause shearing of incomplete bonding.  As much as I believe in the aircraft this problem and the firmware are making me worry about swinging an X7 especially a year out after purchase and especially near people.  The solution is to fix the assembly line problems and send every owner a fixed replacement aircraft before they return their old aircraft.If they continue to fly the old aircraft then the liability rests with the operator who knowingly used a defective aircraft and then they could loose their commercial license.

Hi DJI, do u have any update about the issue?
Thanks, Marek Gura.

Any updates?

Hey, I mentioned about it in my post as I've seen dozens of these issues. In meantime I am awaiting for a response from DJI, I am tinkering with some solutions.

My post: https://forum.dji.com/thread-126448-1-1.html

I looked up few topics from beginning of this year and I am 100% sure there is no any progress from DJI on this, nor official statement - I guess this is due to the fact there is not enough reported cases (or there are, just their engineering team cannot connect the dots). Sadly, I guess we need to wait for something serious to happen for someone to actually take an action and recall these units.

Ouch! That looks terrible... Sorry to see this and hope all gets sorted asap for you!

What happens here is serious enough to report to an authority. DJI, it is time to make a public statement.

HI Marek, is there any progress in your case? What DJI has done so far to investigate your case?

While we are on product safety issues, we should be kept updated about this case.

DTK Posted at 2018-1-15 16:25

It seems all goes very quite at DJI lately, they most likely will not answer on this issues on personal injury .
