Just a heads up, not negetive but fact.
It is against international copyright law to use a trademarked design (the logo) on a product without the express permission of the rights holder to do so.
If your going to sell ten then maybe it doesnt matter but understand that it is against the law.
I personally don't mind what you do ( unless your ripping off the copyright of one of my companies!) but just be aware that DJI could take umbrance and issue a complaint now or some time in the future.
As a note the act of buying something that you know to be counterfeight is also a criminal act in many places.
If you were doing it with Nike or Adidas you would have the same issue.
