Hi all,


My Mavic pro keeps crashing. When flying at high speed (sometmies not even in sport mode) I would hear the propellers scratching at the body of the drone. Yesterday when this started happing again, the drone started spinning out of control and then fell to the gound. I'm using the stock DJI peopellers. I'm planing on getting it repaired locally as my warrantly may be up by now. Do you guys have any idea to what i may need to change in order to fix this issue? My brother trimmed the areas of which the drone blades were hitting... I know, bad move. He's getting the new Mavic air so he gave me this one so now I'm stuck trying to figure out how to get it functional.

Regards,

Something is MAJORLY wrong with your AC. The prop should not cut into the main body at all! These are OEM/DJI/Genuine props, correct? Not an aftermarket clone/rip-off?
Do you feel any axial or rotational play in the motors? Are the props still intact, never gacked or crashed? Does the arm move "up and dow"  when you try to flex it gently?

Try Dis Guy:

If you need service to your DJI Mavic, I can help. I have bought, sold and repaired hundreds of Phantoms and Mavics and have every available spare OEM DJI replacement part for the Mavic both new and used.

I don't ask for any money up front, I will send you a Paypal invoice after you decide whether to fix it or not. Please make sure before you send it to me that your Paypal name and address information are up to date.

I charge $49 to give you an estimate of the damage. It will take 2-3 business days after I have received your Mavic to generate the estimate, and I will email you when the estimate is complete. The estimate is just that, I will determine what the error messages are and what physical damage is apparent, but if I find any additional things that need to be repaired after the estimate, I will let you know before I finish the repair and wont proceed until I get your approval.

My repair rate is $49 per hour or fraction thereof, and if you decide to repair it, the $49 estimate fee is applied to the repair. Before I send your Mavic back to you, I normally calibrate the IMU and controller and take it for a test flight of at least 3-5 minutes.

Turnaround time for the repair is 3-5 business days after you have accepted the estimate. After your repair is complete, I will contact you and let you know it’s done and send you a Paypal invoice. I accept Paypal only as payment, and my Paypal address is Thunderdrones@aol.com. I use USPS Insured Priority Mail as return shipping and I will bill you the cost of shipping along with the repair cost after it’s done.

Thank you for your reply, unfortunately where I live, shipping outside of the Caribbean is really expensive.. that's why I decided to do it locally.

I don't feel any axial or rotational play in the motors. The props are new also. I was hoping that this was an issue that others may have also experienced so that I can get more of a second opinion before commencing repairs.

Damn that is a seriously defective drone, did somebody stand/sit on it! The left hand side of the drone is seriously bent/twisted.

No, the front arm got damaged during the fall. I'm thinking about changing out the entire shell as well as changing out the arms. I'm hoping the guy I go by to repair can delve deeper into what's causing the props to hit the body.

Do the other blade/arms "track" at the same angle? Not front to back, there is a differential angle in design front from the rear prop angle.
The left front prop track the same as the right front prop? and same for the rears?
Either something is bent/flexing to cut into the body, or over extending, or the props are not right....

There is a dji service center in Costa Rica, closest to you? Or Puerto Rico?

They look as though they have the same angle. I'll try ordering props from DJI store and see if it makes a difference. Could it be that something is wrong with the arm?

The back left arm however can be pushed up as the tiny lid which stops it from going higher than the original height was trimmed off.

it seems either the motor is misaligned or the arm maybe bent slightly, possibly either from a crash or someone stood on it. it might have been better to cut the props a bit shorter than to cut the body but anyway how to fix? i would suggest an entire new leg with new motor and a new body/frame. at least get those holes covered to prevent foreign objects falling in.

Thank you very much for your reply. I agree, the blades should have been cut rather than the shell. Where do you recommend that I order these parts?

i would recomend you get then from who ever you can find who will send it to you. in south africa i cannot get items from some companies because they do not post to here so i end up looking for places that do post to here and invariably end up paying premium:-(
My best recomendation though would be for you to bite the postage cost bullet and get it to a professional repair person.
They will have the unique tools required and the know how to deal with things like ribbon cables and proper rebuilds ect.
If you were just replacing the arm i would say give it a try but swopping out circuits ect should be done by pros.
Otherwise try to get just an arm and try to replace that and fix the body with duct tape and see if that works.
I wish you luck on the repair

I disagree.  The props should not have been trimmed.  NOTHING should have been trimmed.  This thing is obviously seriously crashed and damaged.  You shouldn't treat the symptoms.  Treat the problem instead.  Fix it right.  I suspect the arm axis has been damaged, similar to one previously posted.  If I understand what you wrote, the arm will move up and down more now that the body has been trimmed giving it clearance.  This is wrong.  The arm should not move at all, other than to rotate back for storage.  The same for the rear ones that flip downward and forward.  All of the joints should be tight, no play/slack.

Indeed nothing should have been trimmed. My brother is a bit weird... there is a play on the back arms and I would look into changing out all arms as well as the shell so everything is intact. It’s better to be safe than sorry.

I have the same problem, see this picture of my MP.

Wow, is the same thing.. I”m going today to have it checked out. I will update with what Technician has to say.

Looking at those pics I would say that the drone has simply had it's day and it no longer fit for purpose. It would be a serious risk flying that. Send it out for a serious repair or better still sell as spare parts and use the money to put towards buying a new one.

So far it seems that changing out the entire shell together with its arms are still way cheaper that purchasing a new one. On eBay I was able to get full shell and 4 arms for 140US.

I have buy a new upper shell on Amazone.
On my drone it’s not a big problem, just this corner, no idea about how it came off.
Did not hit anything, only thing a can think of is hitting by the prob, little damage on the prop.

Arm the motors when on the ground for a minute before taking off and see if it still catches.

A CW Posted at 2018-3-25 00:53

No, on the ground they never touch the shell.
This is the strange part of it.
No idea what happens in the air.

Yes, same thing happens to me. When taking sharp corners as well the props would hit the shell.

Shivan, I feel sorry for this. Please do not trim the propellers. Please try to change another prop or switch the prop on the diagonal line to see if the body will be hit. Since the drone was crashed, I suggest sending the drone in for repair. Please contact our support on the following page to start a case: http://www.dji.com/support

Just to verify, you used the genuine DJI props, right? Did the drone crash before? Please also send the drone in for repair for this case since we don't recommend self-repairing. Please contact our support on the following page to start a case: http://www.dji.com/support

DJI Thor, Yes i use the Original props that came with the MP, and never have been a crash.

I hope you are not trying to fly this thing! Crazy!

I spoke to a local technician yesterday and he said that the front arms are not exactly where it should be. During the crash my brother initially had, the shell may have been damaged on the inside, allowing the props to extend further forward than usual. I've ordered a replacement shell (Just the upper and middle shell) to replace the current one. I may take some time to post an update as packages usually take 1-2 weeks before arriving in the Caribbean.

Find someone who can solder, you will need a good quality iron to swap the case and replace the arms. Trimming the case would make the situation worse as it removes rigidity from the mid case. Good luck with the repair, I have repaired much worse back to a healthy (safe) condition.

Thank you, when checking up on Mavic repairs most sites went into detail of how important it is to have a high quality solder as one that takes to long to break the solder can damage the board.

In my case the arms are in correct place and the drone did not have any crash.
So it’s only the little piece of the corner how is missing.
Replace the upper shell and the prop that hit this corner in my case its ready to go again.

Bat I never know how it happened.

DJI Thor Posted at 2018-3-26 00:28

DJI Thor, no need for bat thanks.

Always do an IMU calibration after a crash/hit , even if it fells up side down due to wind.

Time2Party Posted at 2018-3-28 00:14
DJI Thor, no need for bat thanks.

Alright, however, for the safety concern, please take good care of it, or send the drone in if needed.
