I got a little ahead of myself one day and zigged when I should have zagged, branch, gravity, rock... so I am on my second Neo. lol. But I did pop the other one open, for Science, and the mainboard and connectors are all pretty well soldiered and I'd bet coated in urethane spray from the looks of it. We don't get rain often here, but this morning the marine layer was thick and I was sending it for 5 batteries, drone was wet, beads of water on the lens, flew just fine. Thing just keeps impressing.
