The tough part is ensuring they all stay in place during rain, bugs, light hail, cold weather, hot weather, and whatever insults a ground crew might bring in cleaning the unit. All the display would require is a power supply through a slip ring, though the wiring to the blade(s) does have to follow the linkage to the blades - the controller and drive electronics would be about 1 ounce and a few grams for the LEDs. I love mixed units. It might even be possible to build a magneto setup so that no slip ring would be required and just run automatically when the tail rotor turns.
Still, people get in the news for falling into a canyon when they slip from top edge of the guard rail or going past multiple "EMPLOYEES ONLY" signs to pet the lions, so that seems like a lot of effort for the rare payout
Maybe a pre-flight video showing passengers what happens to a pumpkin tossed into a running tail rotor? Where's Myth Busters when you need them?
There is a point, and wondering if there are cameras for the pax to see and have their own dvd copy of the flight. Looking at Paradise Helicopters wondering if their 407 have cameras, like Papillon Bell 407?
