Two issues I could see a problem with: -As somebody mentioned, these things can't fly that high. Is it going to be dangerous to try to fly it over tall houses or buildings? -Even if you can get above street level, is the thrust going to, say, ruin your neighbor's garden? You could have a problem with smaller communities banning these, even if it stays legal.
