This is the simplest and least expensive way to add a strobe to any model, just plug it in to any channel on your receiver, it can even be connected to a channel being used by a control surface servo using a standard servo Y.  Features a single blink (1 hertz) pattern, the function is built right into the LED, no programming or other parts are required.  All it requires is the power it gets from the receiver. The current-limiting resistor necessary for use on a 5-6 volt system is pre-installed, just plug it in and go.  Includes a 5mm plastic holder for easy installation.  Wire length is 30".  Available in White or Red.
