My EVO II began developing cracks within the first few weeks of having it. Short story is that I had my EVO II sent back to Autel at the end of summer for some warranty issues. During that time, they replaced my shell due to the forming cracks on both sides of the body in the same places on both sides. Everyone has had an philosophical answer as the the reason for the cracks. A few days ago I noticed more developed cracks in the same spots as before. I found the culprit! Both sides of the body have mounting screws for the top shell mounting the sides to the battery cage. These screws are not countersunk and protrude outward pressure against the plastic bottom shell on both sides. I could feel the bulge under the shell on both sides where the cracks were formed. I decided to remove the bottom shell to have a look and see if there was a solution to this ongoing issue. The fix is to remove each side screw and then there is no longer any outward pressure putting constant strain on your bottom shell. The top shell is still mounted to the top by several other screws and is still plenty sturdy. Now that the screws are removed, I an no longer see the cracks since the bulging pressure is gone. See the photos for reference. The first pictures are the cracks prior to removing the problematic screws, and the others are of the screws themselves and the location to be found. Notice the picture of the screw alone, you can barely see the cracks anymore without the pressure pushing the shell. The shell is easy to remove for access. You only need to remove the bottom shell to have access. YouTube is your best friend if you wish to do this too. Hope this helps anyone who has a cracking shell and wishes to mitigate the issue to prevent any further spread without having to send your drone back to Autel for weeks at a time. Adios!
