Hello. First post here. I thought I would post my experience in the hope that someone else has a similar problem and can benefit from my solution.

After about a week of flying my Mini 2 I decided to fly it indoors. I hit a wall about 3 meters up and then shortly after hit the ground.

I inspected the craft and found no visible damage. The arms all sat right, the props were in good condition, and everything seemed okay. So I took it for a test flight.

It immediately swung backwards as soon as I took off. I re-calibrated the IMU several times but the same problem kept happening.

I was familiar with the inner workings of the craft from YouTube videos. After looking into the battery compartment with a flashlight I saw that the IMU/GPS board was sitting crooked inside the case.

I removed the 4 screws that secured the top plate. Actually removing the plate was the hardest part, I did not have a proper spudger and managed to unclip it with a flat head screw driver. I recommend you get a proper spudger for this. By the time I had the top plate off the IMU/GPS board was already sitting correctly, I assume it was wedged against the top plate. I did a test flight with the top off and it worked perfectly.

I replaced the top plate and screws and re-calibrated the IMU and was good to go.

If you experience the craft seemingly intentionally titling in a given direction as soon as it gets into the air I recommend you look in the battery compartment to see if the IMU/GPS board is crooked. It is the square board farthest into it on the top with a ribbon cable.

This was a relatively easy fix, but I think I voided my warranty. I don't have the extended protection and this was a not manufacturers defect so I am not too worried about that. I do think DJI could probably change the shape of the mould for the top plate to avoid this sort of jamming in the future but nobody is perfect.

Thanks for sharing.

Great tip - many thanks for sharing

Thank you, if it behaves strangely in the future I will contact support. Right now it is working as good as new.

Nice job.  Glad you got it fixed.  I have done several DIY replacements of arms (1 for my Mini and 3 for other flyers).  Not hard if you have the right tools and steady hands.

By the way, 3 of the 4 arms I replaced were due to accidents of pilots flying inside.  Mine was outside but I missed seeing a small cable and cracked the arm.  I was amazed that it kept flying long enough to safely land.  

Thanks for the post.
Question. I’m a little confused. You said top plate and 4 screws. Do you mean the bottom because the top cover snaps on  and the bottom screws on.
If you can see the IMU in the battery compartment is it below the battery or above it.
If it went back into place when you removed the cover could it be popped back into place threw the battery compartment.

Yes in hindsight I probably could have poked the GPS/IMU with a chop stick through the battery compartment to resettle it. At the top back of the battery compartment.

It was the top plate, I removed the screws on the bottom because a YouTube video said that was needed to remove the top plate, but I am not certain it was needed if you say it just unclips.

Thanks for the update. I had to replace a broken arm pivot and had to just remove the top (no screws) to remove.
But your description was highly helpful to all of us so thank you.
When mine broke the pivot arm I had some cool video of it tumbling down threw a tree from 70 feet up.lol.
