Thank you, I have the 2 year dji refresh but just bought the mini 4 pro two days ago and this hinge broke. Cheap fix without having to send it in. Great tutorial on how to to do this 👍

[@sciencebygabrawy]

You’re welcome! Less hassle for sure!

This is a video I’ve been looking for thank you. I just got my DJI mini 4 Pro. I ran into the wall. I just disabled the obstacle guard😩 Thank you.

[@sciencebygabrawy]

Something I do way too much lol. Glad it helped!

AWESOME video, thanks so much for sharing!

[@sciencebygabrawy]

You bet! Thanks for watching!

[@BravestDawg101]

Holy hell you have steady hands, trying to get those screws in without a magnetic tip was a nightmare for me. At one point a screw fell down the little hole where the wires come out, spent a good 10 minutes shaking the thing to get it out lol. Regardless, thank you very much for the video, I was really worried when it first broke, but less than $15 for a repair and we're back to flyin!

[@sciencebygabrawy]

Yep! A bit stressful when you’ve just spent a good amount of money only to break soon after! It’s great knowing there’s plenty of replacement parts out there. Thank you and happy flying!

that looks so easy to fix

[@sciencebygabrawy]

[@Alhusam]

What a professional and fast job! Unfortunately, my new Mini 4 Pro broke its front right wing in exactly the same way. Sadly, one of the cables attached to the propeller was also cut. My question is: where can I get the original replacement part for that triangle? Thanks, everyone.

[@sciencebygabrawy]

Oh man! Sorry about That! Well in the DJI app, I believe you can purchase anything. apps.apple.com/app/id899147555 But I just use Amazon to be honest. Everything’s there and available. Good luck!

[@Alhusam]

Actually, I have already got that. Your video was very helpful and informative regarding that issue. Thanks.

[@user-hf2fj8wz8c]

Man you saved my day!!!

[@sciencebygabrawy]

Go get ‘em bro!

[@cameragodvisionary]

Great instructional video, I just have one question: if the broken arm isn't lighting up and calibrating upon startup (like the other 3 do) does this mean that I also have damage with the wires as well? Or will replacing the shaft acid hinge fix this issue? My arm is hanging out more than the damaged one in the video.

[@sciencebygabrawy]

Thank you sir! So unfortunately, it sounds like you got a wire issue at hand. There’s always a chance that you could repair the cut wire without having to pull apart all the body shell pieces but if you do have to remove more, I would write down the steps you take being your first time so you don’t forget anything! Btw new arms come with new wires and they’re about $100. Good luck!

[@NicManGun]

I really wish somebody would make an upgrade kit for those cause they break really easy

[@sciencebygabrawy]

Yeah. Maybe there’s just not at big enough market yet. I’ve been really trying to remember to switch back from sport mode to normal mode when the drone is no longer in an open wide space. You just forget sometimes in the midst of all the fun lol

[@NicManGun]

Yea, that’s what happened to me, I lightly ran into my vehicle and it fell 4’ and broke… upgraded axis arm hinges and custom Kydex clip on pieces for the arms and body would make it still really light but extremely strong. I might just buy the materials and do it myself.

[@lincolnikeda]

Muito obrigado!! Eu quebrei esta peça do meu mini3.

[@eadjh98]

Thanks for sharing, just broke mine a couple of days ago , any ideas where to purchase a new Axis hinge please? Subbing to your channel 👍

[@sciencebygabrawy]

Sorry to hear that! Thanks for the sub! Here’s the link for what I picked up from Amazon. a.co/d/9bDIcsz

[@michalralu]

Are the sockets into which the screws holding the arm spring are screwed in, plastic or metal?

[@sciencebygabrawy]

Thankfully metal screws into metal sockets!

[@michalralu]

Thank you very much for your reply! I have one more question - when you move the front arm by the presser foot front and back (unfolded, of course), can you feel a slight loosening?@@sciencebygabrawy

[@sciencebygabrawy]

Yes maybe a little. And now this totally makes sense Michal thank you! In the video I said everything looks great but now that I’m really thinking about it, that axis hinge does seem slightly less powerful than the other side. I mean it’s all made in China, idk. I guess the bright side is that, when it comes to flight performance, it shouldn’t make any difference. If you’re wondering if you should buy original DJI parts, I’ve looked through the DJI phone app and all they have are replacement screws and propellers. My go-to is Amazon lol.

[@michalralu]

@@sciencebygabrawy One more question - does this slight loosening occur on the repaired arm or both? Where the arm meets the body?

[@sciencebygabrawy]

No, just the repaired one because the axis hinge is an after market part and not necessarily made by DJI. Did you already replace the axis hinge and the new one feels loose? If you’re having issues with the repaired arm being wiggly or loose, maybe purchase a second axis hinge. If the new one feels tight, you could take the other axis hinge and return it.

[@iamshredder3587]

Awesome. Thanks man. I was worried I broke it after just a couple weeks owning it and would have to send away for lengthy expehsive repairs. This is much better. 😀 Question: is the back legs a different looking axis hinge that i shoild probably order now in case i break one? Thanks again.

[@Alhusam]

Hello everyone, the transmission cable of my Mini 4 Pro was severed in a crash that also broke the arm shaft axis hinge. What is the best solution to resolve this issue, and can my drone still operate without repairing it? Thanks.

[@sh3llbac]

NICE !!!!

[@ItzJasonJustin]

I messed up bad…. I damaged the screw in the arm and it’s the one I need to take out to put the shaft on… the screw is damaged and won’t come out so I’m unsure of what to do now…😢

[@sciencebygabrawy]

I’m sure you’ve seen those KZbin videos where they put rubber band between head of the screw the screwdriver to help get some traction. Another idea, and this may be way too aggressive, but there’s always the option of using a screw extractor. You know the screw that you drill into the screw, where the threads spin in the opposite direction. Sorry man! Let me know how it goes!

[@ItzJasonJustin]

@@sciencebygabrawyyes I have tried the rubber band and that didn’t work and well the part where you screw a hole in the screw doesn’t work for some reason I’m not sure why I used a corded drill and it’s powerful so I’m not sure😢

[@user-nh5xt4mw4w]

Just flew into some power lines and did exactly this. Identical broken axis hinge. Did the epoxy method work instead of full replacement of the axis hinge? Will try that temporarily while i wait for the replacement part.

[@sciencebygabrawy]

So I did end up using epoxy on the broken triangle piece, but I never used it because I just ended up installing a new one. So I never really got to test the one that I epoxied together.

[@ItzJasonJustin]

SAMMEEE THE WIND AND LOW BATTERY MADE ME HIT THOSE DANG LINES

[@user-nh5xt4mw4w]

@@sciencebygabrawy I just went ahead and tried the epoxy method. The super glue stuck the plastic back together and I have placed the axis hinge back into the arm in its original position. Have flown the drone once without issue however I believe if I pull that arm in the wrong direction when folding it out then it will likely break the axis far more easily again. In summary the epoxy method works but I dont trust it long term so I have ordered a replacement piece anyway in case.

[@GoldenMarky]

how much does it cost and where to buy it?

[@sciencebygabrawy]

[@JMegliorino]

Have a question, did you use any thread lock or Locktite for the screws, if so which do you recommend? Just curious if the vibration from the motors can make the screws vulnerable to coming loose without some sort of thread lock. Thanks.

[@sciencebygabrawy]

I’ve never been worried about any screw that can be tightened down snug but I’ve thought about this question a lot because I recently bought a pack of knock off propellers hoping to save money. When they’re screwed in snug, the propellers won’t spin, so I’m forced to back off the screws a bit. I know sounds like a really bad idea. On several occasions, upon putting the drone away, the propellers would just come off and I’d wonder how did they not fly off during the flight. Anyway, for parts that are not being constantly replaced, like arms and stuff I think it’s a great idea! But I personally am replacing propellers all the time because I like to do a lot of various stunts and maneuvers lol. Well, my worry is after a while that locktite will eventually gunk up the inside of the screw socket from so many propeller replacements. But for arms and that kinda thing? Awesome idea! I don’t think it would hurt a thing!

[@JMegliorino]

Thank you for the response, I just replaced the left arm yesterday, tightened down all the screws, and flew it. Seemed fine but will check them prior & after each flight to ensure they’re tight. Thanks!😉✌️

[@sciencebygabrawy]

Wow! Pretty big job replacing the entire arm! Makes you think twice about using sport mode huh lol. I love sport mode lol. But about rechecking your screws a few times- Good plan for sure!

[@jordanfolkard4009]

I managed to snap one of the arm screws leaving a piece of the screw stuck what's the best way to remove it

[@sciencebygabrawy]

I’ll tell you but please use ultimate caution and precision. Use the smallest finest punch and punch a dent in the center. Drill with the absolute skinniest drill bit you can find down as far as the screw goes. Drop a drop off lithium grease to loosen. Put the punch back in and gently wiggle it out. Good luck.

[@rubelahmed3377]

Camera Lens Error 1C000310 please tell me how to fix it

[@sciencebygabrawy]

Hi Rubel, I’m sorry you’re having this issue. It’s more common than you think, even right out of the box with the mini 4 pros. I hate to be the bearer of bad news, but there’s a good chance that you’re gonna have to send it in to DJI to have it repaired. 1C000310 and 1C000317 are common error when there is a loose connection between the camera lens and the board. You didn’t do anything wrong it’s totally a manufacturing defect. Now, there is something you might want to try before you send it in. There’s a small chance that a simple software reset will do the trick. If it works, it wasn’t a loose connection. A five minute software reset or update is always worth a try. Good luck Rubel and let us know what happens!

[@chizama4110]

What would you recommend of one of the screws is stripped

[@sciencebygabrawy]

Well, if it were my drone I’d epoxy the head of my screwdriver to the head of the screw. Then wait 24 hours. Then I would spray a very small amount of WD40 or lithium grease down the threads. Then I’d try backing off the screw. I don’t know if you have a better idea but anyway good luck!

[@Wilcox93]

what would you recommend if a few of the wires are torn in half too? asking for a friend

[@sciencebygabrawy]

I mean, if the break is in an easy spot to solder, obviously you could solder them, if you can isolate each one and not melt the plastic sleeves etc. honestly, I wouldn’t spend more than 15 minutes trying. If he can’t get it I’d just order a new set online, but you’ll have to take the whole thing apart, unfortunately.

How to get the arm screw out if you striped it

[@sciencebygabrawy]

Sorry about that man. With these small screws, stripping one makes it a lot harder. I saw a video of someone glueing a screwdriver to the stripped screw head with epoxy. After a day, he was able to back it out. Any other ideas guys?

[@ryaldeveau6299]

Such a HORRIBLY weak point!

[@sciencebygabrawy]

Yeah lol. Gotta keep your weight down. Maybe flexible joints is a good innovation for the engineers to come up with

[@ryaldeveau207]

​@@sciencebygabrawy they could of at minimum used glass fiber reinforced plastic instead of just thin plastic connected to a chunk of metal...

[@explorewithvaly]

Indeed .. I just broke mine

[@champikadp]

It a good design IMHO, I just broke mine and got it replaced thanks to this video pretty easily. If the hinge was stiff arm could of broken (at least with situation I had to face) which would be harder and expensive to repair.

It’s good for pilots to work on their own drones as this gives them a better appreciation for the engineering that goes into it! It’ll work bud!
