I've never bothered to take large cameras, lenses, or drones, out of my bag unless specifically asked to do so. A few airports do (in one case I had to take every single lens out and put them in a tray), but most just want the laptop, and some don't even want that. No problems at all so far, and no specific red flags to do with the drone at all.
Occassionally I've had my bag flagged it for extra screening when it goes through the X-Ray, but that's always been resolved either by a visual inspection of the inside of the bag or by a swab test. Seldom takes more than a few minutes extra on the queue.
