Found Another Crack @115.5hrs..

...Found Another Crack @115.5hrs.., emanating from battery bay, right-side, almost the exact same spot as
left side, I now believe this to be a weakness in the structural design rather than a defect in the plastic...

I'd drill a tiny hole at the end of the crack to avoid its "spread." Then I'd carefully fill the hole and crack with a marine product called "Marine-Tex" (white). Expensive, but you can buy a small package for less than 20 bucks. Use care inside battery compartment to remove any excess to ensure later proper battery fit. All this may work for you unless you go for warranty repair, I suppose.

WOW... and I thought DJI had this problem worked out on the P4!
GEEZ.... will they ever get this problem sorted out???
Sorry to hear of your problem though and I hope you get the spread of the crack fixed!

Spotted a very tiny crack close to the motor mount on my P4 after over 250 hours. Contacted DJI and received a Case #.
8 days after sending the P4 to CA (from the Caribbean) I received a brand new quad including Tx shipped by UPS.
No charges

I have the same crack in my Phantom 4, but is smaller of this. My drone is perfect in all other parts and have not crash or hard landings. So I sure is a weakness in the structural design. My Phantom 4 has 3 month and fly very fine.

...Ive already taken care of both cracks, '..to each 'is own..' but I don't think drilling a hole in this case, with this plastic, in this area, would be a good idea.. also am familiar with MarineTex, used it many moons ago (80's), great product.. no way i'd send my drone to DJi for Repair/Replacement again '..to each 'is own..' also all 3 of my batteries have heat-stress crack(s) at/near the indicators...

You can drill a hole holding the bit in your fingers without drill pressure. Slow but not forceful.

I wonder if storing the phantom without the battery would relieve some of the stress from the battery bay?

 

[d4niven]

Hmm need to check out my P4 for this when I get home.

I noticed last few battery changes had quite a 'reassuring' click into place even though pressing the release buttons.

...I like the solution of drilling holes, albeit not ideal.

i always remove the battery after flt and store without a battery

stop drilling a small hole at the very end of the crack prevents it from cracking further. it is the preferred method, even on large aircraft this is the norm !

Grizz1 Please check "goofy *** spell check" May send wrong message. Just sayin'.

I'm just happy I didn't have to fight DJI for replacing my P4 with that battery bay crack like that and for the smaller crack on an arm. April 12th will be my one year mark, so no further replacements after that.

Don't know your jurisdiction but in the UK if it cracked again outside of warranty you'd have a very good claim under the Sale of Goods Act.

 

[John Locke]

I have three days left in my warranty. I guess I better thoroughly check my craft for cracks.

 

[John Locke]

I'm sure glad I read this post, thanks Daemon. After checking my craft I also have the identical crack. I just sent my claim into DJI.

 

[kndll]

now you know why some people have had their batteries fall out during flight !

Exactly like mine was. Looks like you're going to have a new drone in the next couple of weeks.

Everytime I see one of these cracks it angers me.

John do you store your P4 with or without the Battery inserted?

I'm now storing it without in these winter months.

I store mine with the battery inserted most of the time, ready to fly.
