So 20 minutes at say 60 knots = 20nm range. Then you have to wait for a couple of hours to recharge the batteries…. Assuming there is a charger available. Otherwise it’s limited to a 10nm out and back with no loiter time.
As if that’s not enough, if the sound of your neighbour’s drone flying overhead drives you nuts, imagine what a sound level of 100 times that would do to everyone. I’d suggest a bulletproof kevlar flight suit might be essential equipment.
Other than all that, it’s a great idea. If I had USD $92K to incinerate, I’d sign up for one. If for nothing else than to piss off my neighbours.
