Phantom 3 Crack Repairs

It needs to be scorching hot to melt the glue. It may soften it at most. If you touch your motors and it burns you then I would consider using something else...
I've done the same mod to my P2 and I think the also acts as a vibration absorber and prevents further cracks. Think of the cracks as seams in a dress. It only needs 1 fray and it will continue to develop until the dress falls apart.
Did I do this correctly? They are tight, but I didn't pull them like super tight... You guys sure they aren't going to make it worse? I don't have cracks yet, looking toward prevention.
From the other thread that a guy got a brand new one with them already there... It got me thinking.. Its either an 1)isolated mold issue ,aka could be a large percentage, but not all, 2) it's a defect that can happen to anyone, and 3) one or the above AND dji is sending out refurbished units as New and happened to miss this.. The reason this is a possibility is because if it's not a mold issue, but a defect causing a week flight stress point, and there's No way it could come brand new out of the box with this.
I've always had a hunch that dji is selling refurbished phantoms as new when my first brand new one came with some odd scratches and scuffs on the camera and gimbal, a loose gimbal wire, and just happened to have fatal software errors 3 flights in... Too many thinks to happen to a new unit for it to be just bad manufacturing. I think they are refurbing parts and then putting them back on main production line without proper testing.

I'm not an engineer but the UAV Bits strong arm plates look like the best prevention as they spread the pressure from the screws across a wide area instead of in the weak screw recesses. They are a tad pricey at about $25 per set but they are less than a shell.

Just a question for those with zip straps applied. Do you apply and tighten the straps before re-torquing the screws or tighten the screws first before tightening the straps?
Also searched Aus for Bondic...seems the only way is a U.S. supplier who will post it over.
BuckRogers:
Can you update us, how strong is your bird so far with Bondic?
Im waiting for a RMA from Germany, but if they install the old shell, im thinking in buy the new version, and "Bondic" it all...
Thank you!

Have you tried Bondic? You should buy some and use it for different stuff, get the feel of if you will. I did and have concluded it is pretty much good for absolutely nothing, absolutely nothing at all. There are so many very good adhesives available that are far superior to anything Bondic is capable of it would be insane to not use one of them instead.

So I was making a mold of my Phantom 3 in anticipation of having cracks to deal with. I used Instamorph to try to make a form of the arm and screw holes. Instamorph sticks like mad to the plastic of the Phantom. If I was to repair a crack not exposed to the heat of the motors, Instamorph would be my first choice. Structurally stronger than bondic and much better adhesion properties. From my experience I would heat the Phantom crack area to 140 degrees F, heat the instamorph to a cracking 150-160 degrees F. Put a nice patch on it and let it cool down. With a nice clean surface the bond should be extremely permanent and structurally stronger than the original Phantom's body.

Yes this is how they are they have an aggressive response policy to anything negative that is posted publicly. They operate differently from how European companies do because its a Chinese company. As a customer it just frustrates me because they do have the BEST product out there and best value for money BUT their coms attitude towards their customers it unheard of and the WORST for western standards. I wont be surprised if after writing this i will have a DJI fun boy or an incognito DJI employee on my back... if they only understood how to treat their customers... by the way they block people from their fora (forums) without any warning if one expresses criticism. Appilogies for going off topic.
Great glue work and craftmanship on the orignal post bravo!
According to some others, there are 'no issues, design faults'. I beg to differ, there is and hence the introduction of the new motors, enhanced shells.
Well Good news:
After received my "new" supposedly P3A from Germany, not only they keep the top old shell, but they also install a new one under, but the old, defective, shell and not the new model on X...
Also, one of the screws, we can see the shape of crack to appear on the same place and arm, that was the reason to send it to repair.....just love this movie ...

Lets keep this talk?

The introduction of upgrades and enhancements doesn't necessarily mean the assumption that something is "faulty" or wrong with an object by the manufacturer, be it a drone or a TV set or a car. Parts of appliances are constantly being modified and updated throughout a generation's lifecycle. It's just part of industrial process. Sometimes it's evident (in the case of the shell and the motors), others it's hidden and we don't even know about.
Also, there is no positive, absolute and undeniable correlation of cause and effect here. Shells are cracking despite being X or not-X, and with motors both old and new. P3P, A and S alike. And we don't know for sure (I mean 100% here too) the actual percentage of shells cracking X not cracking, so we can't really tell it's a "P3 issue" - except of course for owners of problematic units.
Receive mine yesterday from Germany and already before fly, i see cracks form appear...
Also they did install old shell...
Reclamation on the way....

It's well known if product fails during normal operations, it's either a design issue or a QA issue. Customers should be appropriately compensated in such cases.
