If a pilot were to loose control, as you did, and/or if there were a radio malfunction, the drone could harm or kill someone on private property. Not even the "failsafes" built into the drone can prevent a disaster if one of the motors stops working.
As for the second sentence, irresponsible and ignorant drone owners have led to recent federal action that requires all pilots in the R/C community to register with the Federal Aviation Administration. To say that drone operator have "affected" the R/C Community is an understatement of monumental, and Biblical proportions.
Unless I am mistaken, this has kinda already happened, based on a tens of thousands of posts in the last few months, on various R/C forums. I even have a registration certificate to prove it!
P.S., Titanium Dude: if you are not registered with the FAA, you probably violated FAA policy when you determined that "...the quadcopter works perfectly." If you did so, the fine could be somewhere close to $30,000 or so. Might be time to do a little research.
Someone mentioned a possible "whistle blower" reward from the FAA. Who do I contact?
