A shotgun is cheaper and has better range.
It doesn't matter if it falls from the air there will be extensive damage anyway. If anyone shoots my legally flown $10,000 drone, I will find them and they will pay for all repairs.
Buckshot would be most effective and would still have better range than a net.
Paranoid much, where did I say spy on people. I would never spy on my fellow Americans. I specifically said "legally flown" and yes you are legally culpable for every dime of damages. Don't be ignorant, be informed.
I have extended mine to 45 minutes and it can carry up to 20 lbs. I built it myself but it still has a DJI radio and controller so I am still limited.
Sorry for your pain Anon. You don't know who you could be speaking to on this board. We should try to always remember those less fortunate then ourselves.
