I made a set of night blades and figured I'd give night flying a shot since I don't fly my 300x much anymore. This was my first flight. It was pretty windy so nothing spectacular

Perfect regulator makes some blade kits. This is just their 250 kit.
A little spendy. You could probably make one yourself with some copper tape, a 1S battery and some leds for significantly cheaper. But this takes much of the hassle out of it.
