Maybe I’m missing something.A few weeks ago on a chance buy I bought a small drone, its a HS430 drone on Amazon for 55 dollars shipped, yes its straight from china but the darn thing is pretty easy to fly and has a decent 1080 camera on it, hooks to a phone threw its own WiFi signal and three Batts that run for about 12-14 min with the camera on.
I will say in a grid down it will be nice for someone to just fly it around the house or beyond to keep an eye on the perimeter and for the short cost of 55 bucks a few can be bought and put away for just such a use.
My son in law has a better one that will stabilize its self and can return when running low on Batts. But for 55 dollars you get a birds eye view of your yard and several can be had.
If it connects via Wi-Fi wouldn’t it be useless in a grid down?
