Terrific service as always by PRC. The KBDD blades work nicely. Because they're glow-in-the-dark and are charged up by the UV LED, you can't expect them to be as bright as electrified blades, but they work well enough.
One note: The instructions specify mounting the LED to point at the middle of the blades. Because the LED only makes a band about 1/2 to 3/4" wide glow brightly, I'd advise mounting the LED a little farther forward on the tail boom so that it's pointing at the tips. This gives a nice glowing ring the full diameter of the tail rotor.
