Took my phantom out for a quick flight today. I live on the outskirts of the city and have flown unbothered from my own yard for several days. Today was different. Within two minutes of takeoff three people has congregated, all local neighbors. I don't want them to be concerned so I landed so I could talk. Wasn't a minute before the word POLICE came out of each of their mouths, separately. Not as in, "I'm calling the police", but "isn't that what the police use to spy on people?" I explained that it was made to fit a gopro and showed them that there was no camera attached. Has anybody else run into this and what is your reply to them?
