Statistic:125 flight, 330km, 17 months, no crash, wind not stronger than 5m/s, no rain/snow.
I'm quality inspector in the Aviation Company and I put lots of attention to my aircraft.
Unfortunately during after fly inspection I have found 3 small cracks directly under engine mount. It makes me very sad.

I thougt that this problem is only for older version of P3 Standard and maybe DJI company solved it.
Shop where I bought it said that is my fault and it can not be repaired on waranty terms.

How do you think, can I count on DJI support on that matter or try to look for local servis to change shell?
How much it could cost?
Whats are your expiriences?

Regards
KoYoT

You might take a look at plastaid.  You also might consider decreasing the hard braking action of the AC via Go.

Good luck.

All AC settings are changed to give me a slow, smooth yaw & pan movement be proper for smooth video recording. Acceleration/Breaking always were set to proportional setting. Hard breaking happend few times, it looks more hard when I fly with wind.

I have asked for servis some local company they estimate price for shell switch at ~$100.

KoYoT, I am sorry to hear about your cracking dilemma.  I know you stated that you had your bird 17 months but I would still contact DJI support.  In Europe don't you have a 2 year warranty?  If so they will look at your flight records and DJI will determine the fault. (it doesn't sound like it was caused by you)  When you do swap out bodies I highly recommend using the plastaid that Mark The Droner suggests.  There are many videos on YouTube showing how to reinforce with the plastaid product on a new uncracked body. Good luck.

Doesn't matter even I your settings are in your favor. Some phantom owners have experienced these cracks on various aircrafts. As Mark suggested, Plastaid is a solvent that will kind of fuse the plastic together. And it does work. You might also consider some motor re-enforcements. There have been quite a few posts regarding these cracks, with many suggestions. Nothing to get real upset about until they get really large. No guarantee a new shell won't crack again.
A lot of us have just gotten use to dealing with them.

Mine is produced in 2017 too more then 200 flights and more than 400 km and no crack visible until now. May be you got a bad production charge of the shell.

I thought abou that. Some people reports that they shells got broken after just few flights. I can't imagine how hard need to fly to broke it. I was almost sure when I pass 300km that this problem is not related to my model. Unfortunately it seems that was hidden trouble and even my smooth slow flight did not help at that distance.

P3A with cracks.    @150.00 US.    Bench test and flight tests by service provider afterwards.   All good.

MEK  (methy ethyl ketone) is a good solution. Small amount applied with pin or wire welds the cracks. Used it on mine, with no further progression of cracks. This is a common problem with phantoms.

There are some photos of existing cracks. I just sent warranty request to seller, we will see is it polite so much to help me.
On 3 of 4 arms I have detect small cracks, it was hard to take photos. Maybe I panic too much, but it is professional deviation.

You may not be flying for a long time. Best of luck getting someone to do anything with those cracks. I understand how you feel, but the truth is this has been an issue for a very long time. With you having it now for around 1 1/2 years, pretty sure DJI will not do anything, so hope your seller will.
Those cracks you show are really nothing, but they will increase over time. I wouldn't hold out, but obviously it is your choice. Many of us have been dealing with these cracks for over 4-years now, and I have never seen an aircraft fall out of the sky because of those cracks. But I encourage you to do something to repair them if you can't get any warranty work done. Good luck to you.
