So, I have a few questions. Is shipping free? If not, how much does it cost? How long does it take to get your drone back and is it being shipped all the way to China? I could've been sure they had a branch in California. What specific link do I go to file the request? I went on DJI's website and it's all written in Chinese so I think those are for China residents? Is there one specifically for U.S. customers? Sorry if these have been asked before or if it's a dumb question.
