A Level Drone Project

I am going to be constructing a drone for my A Level Design/Technology project. As part of my research, I need other peoples views on possible ideas and what my target market would want. At the moment I am looking at designing a surveillance drone with an on board camera and possibly a sound system. I am looking at various wing designs (no helicopters) for maximum efficiency. Any and all ideas or other suggestions will be much appreciated :eagerness:
