Drone Pornography can be done from your rear yard / garden!... fly the drone inconspicuously past the neighbours bedroom/bathroom windows!
The noise plus sight of the craft buzzing around beside their property could be a giveaway. You say they also have a Pool?..... saweeeeeet !
Yeah, its a whole new Hobby! I've splashed too much cash into my R/C Drones plus FPV.
I'm actually selling a lot of that gear, to free up funds for new biking gear. My biking is now my priority!
The AR Drone is a fun intro into Quadrocopters plus FPV / Aerial photography. Very nice craft.
But as you find, DJI gear is on a whole new level! Infact nothing flies as good as a DJI drone - their Flight controller technology is cutting edge.
Most of my Drones I built myself, but the goal was to one day use DJI electronics, for a superior machine!
Or, do as you've done, and just splash out on a complete DJI product - big bucks!
