In my experience it didn't work well with a 3 standard. If you lose R/C signal part way through, the drone will continue taking pictures on the planned route, but the app doesn't know where it left off, so when you need to put new battery in it goes back to where it lost signal (not where the battery sent it home), so you end up with many duplicate images, making for much more data to process. Also basically had to fly it back blind as only thing showing up on the app after reconnecting was the tiny preview video.
I tried to make several large maps, (100-150 acres) often ended with huge chunks missing, as well as i stated above, duplicating images as i was pushing the range.
As for the green ticks, can be a struggle to get them all...everything has to be loaded just right. I would like to try it with a pro/adv....as i said it just didn't work well with a Standard IMO. Neat idea though. Also seems that it always underestimated the battery time needed to run the map. I tried to set maps up to maximize battery life, and while planing the missions i would be sub 20 min....figured i could do that on one battery. But in actually flying time, was much longer and took multiple batteries. Didn't help with the duplicate images as stated above.
That's what i remember from using it. Worked fine for really small maps, but struggled on larger maps like i was trying to do. I was trying to map large fields for crop scouting. They have probably updated stuff since then, it was mid summer last time i tried to use it. Gave up, as it was easier, faster, to just fly and manually shoot images and then look at them on my computer to see which area's of field i wanted to inspect.
