one of my players, has a side hobby of building and flying RC planes. So during our game, he wanted over head surveillance, and comm intercept, but the target area was all ready wise to drones( 2 where shot down). So his techie, rigger, B&E guy. Uses a commercial of the shelf, mid sized RC plane, with remote. Modifies it to carry a micro camera, a cheap comm link with signal interception gear. Low tech yes, actually a drone No, but by flying near enough to the sight, he got his surveillance, sig intercept, and outer lay out with no one the wiser. I don't have the exact sheet here but it came out cheaper then roto drone. And sense it was old school radio control, no one was thinking of jamming that freq, or bandwidth.
