Are there any issues related to selling a drone (DJI Mavic Air 2, in this case) which was purchased from the DJI Store for delivery in the US to someone abroad? Is there anything about a US market drone that makes it flyable only in the US? I'm showing my ignorance, I know... but my drone is up on eBay now, and I've got a couple of foreign bidders. They made me think about this.
