Just bought a Spark so I could document the build of our house.. I have built and owned various droned over the last 5 years and am blown away with the amount of tech packed into this tiny package.. So handy and inconspicuous - the builders didnt even notice it! Manually flew a grid pattern at 30m altitude. Loaded into Pix4D and 2.5 hrs later - Voila! now to try with Hangar Autopilot Waypoints (which apparently works with the Spark)
