No visible light emission on the quadcopter. Only the DIY 940nm infrared illuminator module. Capable of flying it total dark (pitch black), after replacing the FPV camera for a starlight one.
Do not let the FPV camera fool you: in the googles the picture is much darker, and not so many details could be seen. I was flying rather blind.
