NeoPixel Color LED Ring Mount for Quadcopter
If you are running Cleanflight on Naze go to Adafruit right now and buy one of these LED rings and install it. You will get an awesome after-burner effect tied to your throttle. As a bonus it will also provide some basis status information.
The LED colors and behaviors can be customized in the Cleanflight configurator.
This fits the 12 LED ring found here.
