Oh, and something else to think about...

If you happen to go to almost any r/c flying club in the country, you'll often see not just one aircraft flying, but many. At the clubs I used to fly at, it was not uncommon for up to half a dozen aircraft to be flying at the same time. This, of course, was in the pre-2.4GHz days, when frequencies were often shared between various members, and you had a key system so that if one person was using channel 7, nobody else could use it until he was down.

With the advent of 2.4GHz, transmitters are uniquely bound to individual receivers, so there's next to no chance of inadvertently zapping someone else's aircraft out of the sky if you switch on your transmitter. In fact, theoretically, if you had 100 club members, you could see 100 aircraft in the sky.

Now what does this mean in terms of the DroneGun? Well, imagine 100 rogue aircraft in the sky at the same time....

EDIT:
Back in about 2005/2006 there was a model aircraft on the market that had, of all things, an autopilot. This was a training aircraft, and you could program it to fly straight and level if the student got disoriented. If I recall correctly, it only worked if the sun was within certain angles above the horizon of all things, although I can't remember exactly what triggered it.
Anyhow, a new pilot turned up at our club with this aircraft, and told me he'd disabled the autopilot function. When I asked why, he told me it was because CASA didn't want model aircraft flying without any means of control from the ground.
