MAVIC PRO Rear Arm loose when unfolded - Side to Side

yesh_pwease · May 15, 2018

Hi, I have had my mavic pro for almost 4 months now and I ensured all arms were rigid in every direction before flying and they were all fine.
Just today before going for a flight, I realised that the left rear arm has a decent amount of wobble side to side when unfolded (instead of the up and down folding movement). Worried me too much to fly since I did not want to lose my investment due to the part failing mid air. I have attached a video showing the left rear arm (loose one) compared to the right rear arm. Please share your thoughts

@Thunderdrones will know straight away what is wrong. I say flux capacitor, but have been known to be wrong before.....

Another video from a better angle showing the side to side movement... Sorry for the noisy picture

It's so hard to find plutonium these days! lol

OP, check these 2 screws and make sure they are hand tight, but do not overtighten.

Do you happen to live in a hollow dead volcano?

The screws are as tight, Anything else in mind?

Try pulling the arm out laterally, not folding it, but pulling on it. Not hard, just see if there is any movement. If not, youre probably ok.

So pull it to the side away from the body?

Yes. It shouldnt move very much.

Thanks heaps, so even if it has a but of give side to side you dont think it will be a problem?

As long as it flies straight and the tab above the joint where the arm connects to the body is not cracked, it isnt going to fall off or affect your thrust line.

@yesh_pwease I have noticed a similar issue on my MP.
Not sure it it was caused by a crash...
So far it does not seem to be a big issue... if it gets worse.... I'm gonna replace the arm pivot as per attached photo.
