After reading about many people having small cracks near the motor mounts I started checking mine every couple flights. I only noticed a few on two motor mounts but wasn't too concerned. Then it started to make a very strange noise when flying. When I checked the cracks had connected between two screws on a single motor mount and made that motor loose and not stable. I contacted DJI via email through their support site and had an RMA # with free shipping label within 5 hours! Repair covered 100% under warrantee! Ticket Received - Problem Report - Tue, Dec 15, 2015 at 11:51 AM RMA Issued: Tue, Dec 15, 2015 at 4:17 PM It took me a while to get it in the mail but they only had it for 8 calendar days before shipping back to me. They received the unit on 12/30 and shipped it back to me on 1/6 Then I finally got it in the air today and went through two batteries with no issues, looks like they just put everything into a new shell. No stickers on the new shell but I used the extra stickers included when it was new. I know there are a lot of posts about issues and problems but I wanted to share the great customer support I received and help future potential owners feel comfortable about the company.
