lol people like this need to crawl back up the dirty mothers snatch where they belongquit yappin, if you are dumb enough to shoot down a chopper flying near your house you are a complete moron.
... in Israel they already have remote control dragonflies, wasps and hornets that take images , spy on,, and dub-plate ppl!!
Rather than risk your liberty shooting it down you simply need to remember that anything radio controlled requires a signal at a certain wavelength. If you want permanent 'Anti aircraft' cover then all you need to do is broadcast the R/C wavelengths in your grow area. When they come flying over they will drop from the sky as the controls are rendered useless. Much safer than shooting into the air and having some old lady 2 miles away keel over. Shooting at those puppies will no doubt get you charged with endangering the public, destruction of public property, criminal damage, all kinds of nice fineable things. Shooting at them will also give you away and make you a surefire target. Cunning will always defeat brute force.
Alternatively you could broadcast a stronger signal and take control of it yourself. I'm sure they'd be very surprised to see thier own helo go rogue on them and start straffing their car! lol
Guys here is a good video that shows how this works and the video is pretty funny as well. But my brother is Holland you are not alone, the US Forest sevice is buying drones to nab those outdoor guys as well here in the US.
On a serious note guys lets put our stoner minds together and figure out how we stop this bullshit. I've read way to many threads of how to grow a weed in a trash can and build a fucking grow room from garbage. I know we can figure out how to work around this one. And shooting down is a bad idea. Probably same penalty as killing a police dog. So high powered lazer in the eye might hurt? And this is just the beginning for those of you thinking legalization is coming. I don't want to say much but UAV's have had issues with the FAA until just recently, fighting fires is the crack in the door they will need to get these flying all over our skies.
