I tried integrating a microdrone into my layout several months ago, shown in #40 of my LCJ&I Lines video series:

I found microdrones very skittish and hard to control. Even though the one I used had a HD video camera, it wasn't nearly stable enough to take layout pictures, so I faked it by waving a video camera slowly over the layout. But it is interesting that a microdrone seems about O scale, and fits nicely into the layout scenery.
