How do I find the date my Phantom 3 Professionals were made/released?  I have two.  Where can I send their serial numbers to get back their production year?  I need this for my insurance company.  Insurance people require this before they will confirm coverage. Any infor would be greatly appreciated.

Hello andisoa, basically you can send an email to support@dji.com for this request. The serial number and activation account should be included in the mail. Thanks.
