This is the "No-Signal" version of our Single & Double Blink Strobe, which does not require an active RC signal.  The No-Signal version can be plugged into any channel on your receiver, even a channel currently being used for a control surface or other device, like retracts.  It will come on as soon as the receiver is powered, and stays on until the receiver is powered down.  It can also be used on a "static" model that does not contain an RC receiver.  Just apply 5.0 volts or more, and it will work just like the switched version.  You can view the No-Signal Version here.
 
For those models like gliders or trainers that simply need a single strobe for visual recognition, or scale models that need a single strobe for scale accuracy, this circuit uses a single LED that can be set to blink at either a single (~1HTz) blink, or a quick double blink that can be switched on/off from the transmitter.  Now available with three different size LEDs (5mm, 8mm, or 1-watt emitter) and with red or white LEDs, to make it compatible with models ranging from small indoor flyers to larger scale models and gliders.
 
Select your LED size from the drop-down menu at right.  The 5mm LED is scale for indoor flyers and models up to approx. 48 inch wingspan, the 8mm Straw Hat LEDs are best for giant-scale models.  The 1-watt emitter can be used on any model (it is relatively small), and is very bright, but unless it can be embedded into foam, it will need to be installed under a dome or lens of some kind.  Select the strobe color in the same way, using the drop-down menu.
 
This circuit is regulated for use with any receiver voltage, including 7.4 volt LiPos and Li-Ion packs.  It does not require a separate regulator.
