Parrot AR Drone 2.0 – Repair Part 1 of 4 – Remove Central Cross to Replace – Step by Step

Part 1 of 4. Topic = Parrot AR Drone 2.0 – Replacement of the Central Cross PF070036
This is a detailed video where I first remove and then replace a broken Central Cross.
It takes circa 120+ minutes all in (to the point you can fly again). I explain what tools and parts you need and then talk through step-by-step how to perform the removal and then the new part instal.

I created this video with the YouTube Video Editor (http://www.youtube.com/editor)

    I think its kinda dumb they made one of the most likely pieces to break, this hard to get to.

    Thanks for this video!  This was a lot of fun replacing the cross and motors.  I was able to get the connectors off the board by moving them out to the stops, then inserting a fine point tweezer in the gap and this forces the arms out a little.  I reinstalled all the motors, the unit went "green" immediately and I hit "take off" , the unit immediately crashed and broke a gear on the motor…it was cracked before I’m sure.  I’d recommend ordering a gear and propeller kit with the cross just to save time.
    also, as mentioned above, a fine point tweezer is very helpful positioning these tiny screws.  I also did disassembly over a small box, definitely caught some screws headed for the floor.

    You take excellent care explaining all the steps, but once you start this whole process of replacing the cross just takes 15minutes.  The motors take a few minutes each, label everything.

    Ryan. I am glad that you find them useful and like them….. and yes. It REALLY does help to know that these help. I found the Parrot ones lacking. These are certainly not perfect… But they do share step by step what issues and successes I encountered!
    As I crash and need to make more repairs – you can be sure I will make a half-decent video of whatever unfolds.
    Many thanks for taking the time to comment. 😀

    This guy doesn’t know what he’s doing. He pulled those ribbons out wrong and broke the clips. Use the parrot website or find someone that has tried it before posting a video.

  5. Tom Strong Reviews on December 20, 2021 at 11:38 am

    Thanks for the feedback. Does the Drone always fly to one side ? or just ‘out of control’ ??
    Possibly the ribbon edge connectors need to be removed and re-seated. Also worth double checking that the downward facing camera is aligned ok with the hole in the hull.
    + make some tests. Will the AR Drone still notice it when you tilt the drone ? hold Drone, start to take off and then flip it over. Does it say ‘Tilt emergency’ ? still ???

  6. Tom Strong Reviews on December 20, 2021 at 11:41 am

    I know and show that they are needed, I re-insert them in the re-assembly section of video. (both with only one clip intact)
    They were not easy to remove & the Parrot video did not show the technique you describe. I followed the instructions that Parrot provided….

  7. Marv Hein on December 20, 2021 at 11:42 am

    I found this series of videos very detailed and extremely helpful. The only suggestion I have is one I found a short video on elsewhere. To safely and easily remove the ZIF connector for the front camera (the one sandwiched between the two halves of the motherboard), also remove the Phillips head screws holding the left side of the motherboard to the frame. The motherboard then easily comes apart at a single hard connector and the ribbon is freely accessible without being bent or pinched.  

    As you allude to in your text comments at 4:42, ease the black portion of the ZIF connector just "slightly" out of the white socket by applying a little pressure at each end. It does not have to move much to release the ribbon and should stay attached to the white socket. Without being angled through the slot in the motherboard, the ribbon cable slips easily out of the connector once the black clip is loosened.

    UPDATE: The "hard connector" is not that "hard". After a couple of central cross repairs, which required me to separate the motherboard, the connector pulled loose from the motherboard. It’s hard to see that this has happened, but if you reassemble your drone and get a PIC WATCHDOG EMERGENCY message, there’s a good change it’s that connector. It is a surface mount connector and does not attach with pins that go through the board. I was not able to resolder it onto the board. Use extreme care working with this connector and try to only disconnect and reconnect it once. Keep pressure on it when plugging the boards back together so the female side can’t be forced loose from the board. Install the Phillips screws again so the motherboard has support from the frame.

    For reassembly once your cross is back in place, the camera cable WILL reach without going through the slot. Attach the nav board cable first, then the camera cable. For each, simply slide the ribbon straight into the connector and lock the black retainer back in place. This routing of the camera cable is not ideal, but it’s better than having to buy a new motherboard because of a broken board connector.

    Otherwise, your videos gave me great piece of mind as I performed this repair! Thank you!

    Hi, thanks for the video, I replaced the cross like you described, however when I turn it on, instead of hovering it flips over to one side. Any idea of what I did wrong? Is there a way to calibrate it ?

  9. Tom Strong Reviews on December 20, 2021 at 11:44 am

    I just wedged the broken clips back into place with the one damaged leg and they seemed fairly secure. My AR Drone flies just fine. If you do use a glue – find one that can be easily removed. Like the type companies use on the front of magazines when they stick ‘free’ CDs to the front covers.

  10. Stephen Richard on December 20, 2021 at 11:46 am

    I am wondering if you can help me solve a issue, using your video here I changed out the Central cross on my AR Drone 2.0. I also put in new high speed gears and bearings I have put everything back together and took the drone out for a test flight today. Everything powers up and the motors spin, however its almost like something is reverse wired on one side because the drone wants to turn on its side. Even when holding it in the house in my hand I can feel it pulling to one side. But all 4 blades spin.  What could cause this? Did something get cross wired somewhere? What things could I check or test to try and determine how to fix this?

  11. Aja Dam II on December 20, 2021 at 11:46 am

    what kind of mother board is it

  12. Jackson Ingalls on December 20, 2021 at 11:46 am

    So how the hell do you fix it

  13. Larry Simmons on December 20, 2021 at 11:48 am

    I’m getting an motor emergency error….won’t get off the ground

  14. Larry Fernand on December 20, 2021 at 11:48 am

    Hi tom, it seems that my battery connection is loose. Is this normal?

  15. John Hawes on December 20, 2021 at 11:49 am

    Hi Tom, I was wondering if the replacement cross had the legs connected to it because my current (broken) cross has a missing leg from a rough fall.

  16. 73stratocaster on December 20, 2021 at 11:49 am

    I replaced my central cross and now all of my motors run backwards. Props are correct, but it blows the wrong way. Whats up with that?

  17. G Force Gaming on December 20, 2021 at 11:50 am

    Hello I was unplugging the connectors to the mother board and the black prices broke how can I fix them?

  18. Jason Brown on December 20, 2021 at 11:52 am

    I ha e seen this jellow affect but it didn’t bother me… All my smart phones have had that for years… At least I think I know what you are talking about regarding the jellow.. I have ordered all new props, pins and gears so hopefully I will report back that it’s fixed…. Bte why did you ask about the jellow affect?

  19. Sahir Sutar on December 20, 2021 at 11:52 am

    I connected everything back and turned it on and my phone said camera error.

  20. Tom Strong Reviews on December 20, 2021 at 11:53 am

    This video is part 1 of 4. You may find watching the remaining 3 videos helpful.

  21. Sam Shaw on December 20, 2021 at 11:53 am

    Hi Tom,

    I replaced the cross section like in the video, but now when i take off the drone flips upside down, the propellers are on the correct way there just not turning the correct way. Do the motors spin a different way round? the only thing i can think of is that i put the motors back in the wrong positions.

    Regards

    Sam

  22. Larry Simmons on December 20, 2021 at 11:56 am

    I was wondering if you can help me…I put a new cross member in and did not mark my motors..at a loss on how to fix this

  23. G Force Gaming on December 20, 2021 at 11:56 am

    Pieces sorry

  24. Yska363 on December 20, 2021 at 11:56 am

    What do you do if you break the ZIF connectors? Can you buy replacement connectors or do you have to buy new boards?

  25. Watching in 3d on December 20, 2021 at 11:57 am

    were i buy them connectors as ive bought 4 of these all got broken pins but i got em cheap for diy. im well happy but were i get them? and whats the proper name for them?

  26. Jason Brown on December 20, 2021 at 11:57 am

    Thanks for responding, I didn’t get to fully explore its symptoms today BUT it seems to drift to the same side. Today at work I played with it indoors and it seemed to mostly hover ok but it would occasionally drift and occasionally it would drop and climb. I will forgive today’s symptoms of due to work stations and tables everywhere. Can a electronic part inside function interminably? I was hoping to look at the rotors tomorrow.

  27. Awesome Pizza on December 20, 2021 at 11:59 am

    Is it possible to take out the motherboard without the official tools but your ordinary tools from any store?

  28. Gary Hardy on December 20, 2021 at 11:59 am

    Scotch tape! When you fold back the ribbon cables, use a piece of scotch tape to hold back the ribbon cables. It makes the job easier and you’ll be a lot less likely to bust one of the ribbon cables.

  29. Ties Rademacher on December 20, 2021 at 12:04 pm

    Great video! Thanks to you I’ve repaired the central cross myself. I did a flip at 2 feet high and it felt on one of the arms and broke. After watching your video’s several times I repaired it just like you did. Otherwise I had to pay €40 repaircosts. So thanks again! PS see my flight here in the French Alps AR drone 2.0 flying in the French Alps! :).

  30. Frank Baritell on December 20, 2021 at 12:04 pm

    Hi Tom, I broke one of the little clips as well. The smaller one from the sonar, or what ever it’s called. My question is, did it fly ok when you installed the with one broken side of the clip, or do you think I should put a small dab of glue to better hold it still? Not on the contacts, but on the top. Do they sell new clips? Thanks

  31. Thomas Kim on December 20, 2021 at 12:07 pm

    This video helped me to fix central cross then now my AR.Drone 2.0 says "Pic Watchdog Emergency" TAT

  32. bmoviestgams on December 20, 2021 at 12:07 pm

    Hello! Can i change the controller(motherboard) of the drone ? I’m thinking to put a kk2 controller. Because i needed for one project. Is that possible ?

  33. Davy Jones Locker on December 20, 2021 at 12:08 pm

    Thanks for this, since early on in it’s life (1st week intact) my drone has been erratic and one prop kept hitting the housing, never seemed to hover stable and only now when I was about to bin it did I find your video. Cross member in 3 pieces!!! Hopefully problem solved. $60 for tools + crossmember = $300 saved on written off drone. Thanks again.

  34. Yska363 on December 20, 2021 at 12:10 pm

    Wish that text was on the video before i made the same mistake

  35. TO DRON on December 20, 2021 at 12:10 pm

    Me suscribo espero obren de igual modo gracias.

  36. Jason Brown on December 20, 2021 at 12:11 pm

    GreaT video, but I have a question, but AFTER SWAPPING all the parts my drone now dives out of control to the side. And I think at some point I saw it display Camera problem… Any advice? I thanks again for such a detailed video.

  37. Andreas Wendelboe on December 20, 2021 at 12:12 pm

    What if you don’t have those special screwdrivers need to unhook the circuit board

    Hi Tom
    I didnt read all the comments, but you might want to edit this video.
    Those 2 ribbon cables that you broke the plasic holders, they are needed, they are to used to press the connections pins on to the board, u only need to push them out about 2 MM to release the pressure, then you can pull the cale out

  39. Tom Strong Reviews on December 20, 2021 at 12:18 pm

    I did not explain fully – The ‘Jello’ effect is when there is actually a vibration about your AR Drone 2. Looking at the video when in flight reveals this very easily.
    However – I do recommend that you have a full exchange of Props and Pins so that you can be sure.
    (It may also be worth while checking out some of my other videos on how to change / test / check / all is well. You also do not want to also find that you have damaged gear teeth) Good Luck!

  40. Tom Strong Reviews on December 20, 2021 at 12:18 pm

    The screw driver is just a cross head screwdriver on one end & a flat head end on the other. Nothing special.
    You will need something to help you guide on & off each circlip though.

  41. Mikey D on December 20, 2021 at 12:19 pm

    I totalled my AR drone chassis, found this video and managed to restore it back to new.

    Thank you!

  42. Tom Strong Reviews on December 20, 2021 at 12:20 pm

    I agree with you. For it to break so ‘cleanly’ – it is a design flaw.
    ok – I will make the video. Just need to dig it out again.

  43. Tom Strong Reviews on December 20, 2021 at 12:21 pm

    Testing indoors is always a good idea – you can exclude topics such as cross-winds.
    However – Other things can affect flight / hovering such as ‘warped’ props or ‘Warped’ Shafts.
    If you had a serious crash – you need to consider checking all 4 Props and 4 Pins. (I show this in other videos on my channel).
    Q. When you record video whilst hovering indoors. Does the Video show any evidence of ‘Jello’ / ‘Jelly’ wobble ??

  44. Alan Joseph Bauer on December 20, 2021 at 12:24 pm

    I think that it would be a great contribution. Parrot seems to have a business model based heavily on selling replacement parts. If you can show others how to keep their drones flying with a fixed up crossbar, maybe they will work harder on making a sturdier drone in the future.

  45. TO DRON on December 20, 2021 at 12:26 pm

    A mi dron le conecto la batería cargada y no enciende el dron….que puede ser.???

  46. Tom Strong Reviews on December 20, 2021 at 12:27 pm

    Glad it was of some help 😀
    I have also ‘fashioned’ a repair of my broken one – in case I break my new one. Similar idea, but I also added 2 washers above & below, 4 zip ties tightening them into a compression type joint. (I might make a video to show later this summer)

    Hi I have a problem with my drone. Yesterday was the first time I tried to make it fly, and I have to admit it’s not something for me: my drone hit agaisnt the tree. But it was totally normal, I continued trying a couple of time and it didnt have any problem but today, when it takes off it has 2 lights red and 2 lights green, and it keeps turning around by 360 degree. Can you please tell me what’s its problem? Thank you in anticipate.

  49. Alan Joseph Bauer on December 20, 2021 at 12:33 pm

    Tom–thanks. Very nicely done and a great help in fixing the crossbar. I removed the broken one, glued it with heavy-duty epoxy and used three zip ties to hold anything in place should it break again. Put the bar back and will watch how it flies, before I switch to new part, which could just as easily break.
