I don't know how approachable or mad he currently is, but I always offer to let them fly the drone. (I can be rather persuasive)
When they get their hands on the sticks and see it move on their command, their attitude changes considerably.
I'm also explaining to them how the camera has a wide angle lens on it, it doesn't zoom into backyards, that I don't care about backyards - they are boring, and that Google and Apple fly over their backyards all the time. If I want to see someone's backyard, I just go to the internet.
