Thanks for the reply. I know I have more reading to do, but I am in one of the 300 blocks. Does that mean possibly that I could fly as long as I stay below 300 feet? All I would really want to do is fly a max of about 100 feet anyway. The main reason for flight around my house is roof inspection. I sent an email to DJI support but have not received a response. Has anyone had issues communicating with them on a pre-purchase basis of conversation?
