Browsing Amazon, I came across this flight tail. I can't see how this could improve the flight characteristics of the NEO. Maybe if it was a fixed wing drone?
For orientation assistance, those flexible plastic stick-on bookmark stickers work well. I used a red one on the first drone I flew. Without the tape, it was difficult to tell which end was which when it was more than about 60 feet away. At least the bow and stern are different colors on the Neo.
