We use for yotin' and pasture checks. General rule with EVO2s is 30min cycle time. I.E. roughly 20 mins over "target area" with 4 mins travel out and 4 mins travel back and 2 mins for battery change on the ground. So consumption is 2 batts per hour. 8 batts required for 4 hour sustained ops. Biggest variable is the wind.

I was testing those "landing pads" to see if that would help the auto-land be more precise. I saw no evidence that it did. But the landing is really precise 99% of the time within 2 foot.
I am always watching the landings and ready to intervene if required and it is required sometimes in tight spaces. And around where I am, I'm usually in tight spaces. In swamps or other drone-bad terrain, we run the TOC out of the truck bed and land/take off from the cab roof.
