GemFan Starlight LED 51433 Tri-Blade Propellers
GemFan have always been the innovators of LED props, and the latest Starlight prop is their best one yet. One blade on each prop is set up to accommodate a custom LED strip, so you get full light on the blade, not just from the hub.
And of course, they fly great too!
Note: requires two button batteries, not included.
