My Octocopter UFO…
using an adafruit pro trinket which is basically a mini “Arduino” to read 3 standard ppm channels from my RC receiver to decide which sequence to display. I also have the nav lights on a “oh crap” switch so that I can always get to them if I get disoriented.

For the lights themselves, I am using a neopixel strip also from adafruit.. https://www.adafruit.com/product/1138
