Not just for RC! Try using them to light up your car, your wall, or even your pumpkin! Strips are 100cm long with 60 LEDs spaced every 16 mm or so. They are wired three LED in series so you can cut them into mulitples of three LEDs. There is a an easy to solder tab on each side of the groups of three so you can make custom strands. You can wire as many strips together up to the ability of the battery to support the load. Each strip comes with a set of bare wire leads. There is a pressure sensitive adhesive on the back of the strip. Just peel away the backing and stick the lights to just about any surface.
See the picture below for an example of a solder connection.
