Mavic 2 front leg replacement problems.

@Vinylimage, thank you for the additional information. I'm sure it will come in handy for other people who are interested in doing this repair.

Hi all, my name is Jon, I just wanted to say that I am the person who made the video on replacing the two front legs, and I thought it would be beneficial to provide an update after the repair, I have been getting a lot of traffic to the video and assumed this forum may be the reason why.... in answer to wether I tested the LED, no I didn’t, while it was “broken” I turned It on, the LED’s performed as they should, I turned it off, repaired it, and then turned it back on and they worked the same, so assumed all was good.

thunderdrones is obviously a mountain of information and knowledge, and I read many of his posts and information before even tackling my repair, so obviously take his warnings seriously, and I will confirm I am not a repair specialist and this is not my field of expertise, but I have repaired many phones, iPads and other technology in the past so felt confident enough to do this.

I wanted to address the points he made...

using the small screw driver to pop those wires didn’t nic anything, the wires are abit more robust than people think, go easy and you’ll be fine.

I used almost no pressure at all the when using the pliers, and in all fairness I’m sure I could have used a pair of tweezers instead, but he is right, pliers should probably be avoided.

I replaced both front landing legs, and made the holes in the same place on both sides for the LED’s, and had no problems at all with the LED sitting back down flush, exactly where is was originally positioned, and the cover clipped back into place perfectly fine.

Moving the wires to make manovering the leds through the hole caused me no issues at all, if your gentle and don’t approach it like a bull in a china shop then you shouldn’t have any issues snapping wires.

And finally the hot glue I used was all I had, I figured securing the pieces again was more important than the stuff I used to secure them, I used a tiny tiny amount simply to secure the antenna and wires back into place as they were originally.

Since the repair, I have flow the drone around 30 times and have had no issues what so ever, so I can confirm that my repair was not only successful but I would say simple enough for almost anyone to carry out with abit of care, this is not intended by any way to replace having your drone fixed by a professional, but not everyone can afford to do so and some people like to do it them selfs, and this is a method i made to do so.

I hope it’s helped a few people. [emoji1303][emoji1303]
Yes I'm sure it helped that you had repaired many phones in the past. That's what I consider microelectronic experience, and it is essential before you even try to tackle a project such as this.

To the person who attempts to tackle this on his own, you should have the right tools, the right experience, take your time with it, and if something goes wrong try not to make the problem worse. A "simple" repair such as this could cause you to have to replace the whole arm and void your warranty if you accidentally break something else when all you are trying to do us replace the leg.

Repair successful. Cut out the center to make a cross like hole in between the snap holes for the led cover. The whole lcd assembly slid right through and out. No need to solder the led with this method. process took 20 minutes. Thanks for the assistance now my new drone is new again. Thanks for the tips fellas!

Where did you get the replacement M2 legs from?

Ebay: Looked like a new arm. Shiping took about 5 days. All I used was the plastic leg... keeping the rest of the arm for spare parts.

Nice work! Thank you for sharing your photos.
 
TBH, @Geronimo76 got lucky that the antenna wasnt glued all the way down the leg. Most of the time, the antenna is glued all the way into the leg, and you cant get the glue to let go without completely ripping apart the leg. When you go to remove the antenna from the broken leg, if you are not careful, you can sever the antenna lead, or break the antenna itself, and it is not reparable, you will need to replace the whole arm, and then you will void your warranty and/or break something else in the process. If you have never soldered bcak on an arm or leg, sometimes simply replacing the leg is best left to the pros.

How would I know? Ive done many and I specialize in Mavics.

Be careful when doing this. It is not as easy as it sounds.

Well I do laptop and phone repair for a living so I wouldn't say it was all luck :p. The two arms Ive taken apart had a few spots of that black glue holding the antenna in place at the top of the leg and the wires. I used the tips of my tweezers to remove that before removing the antenna. My bigest fear was breaking the LED wires when fishing it through the new larger hole...as I did not want to replace my LEDs.

Thunderdrones is correct if you don't have experience working on electronics I would not recommend trying this if you have a warranty.

Sorry, I didnt mean to say you were lucky that you didnt break anything, I meant that you were lucky the antenna wasnt glued all the way down. When it is, it turns an easy repair into a nightmare, "what have I done" repair.
 
lol Its all good Thunder...I knew what you meant.

DJI definitely wanted to increase their repair income by moving the LEDs into the legs on the mavick 2. Someone should design metal leg protectors that snap around the base of the legs to avoid the props from eating the leg, antenna and LEDs when the arms fold in during a crash.

Good idea. The problem with metal around th leg is that it might disturb the signal, not sure though.
