Igniters for Composite Motors

The copperhead igniter is use to launch most of the smaller composite propellant motors. For bigger rocket motors, we recommend the First Fire Jr. Igniter, because it is more tolerant of rough handling.

The Copperhead is a unique design that looks like a single part. But actually, it is made from two copper foil strips; that are separated by a thin insulator. The insulator is actually an adhesive that bonds the two foil strips together.

To use the copperhead, you must insulate one side of each micro clip by using a piece of tape on the jaw. Then just attach the clips to the tail of the igniter, with the insulated sides of the clips on opposite sides of the igniter. At this point, you'll have continuity and you can fire off the igniter. I recommend a 12V car battery to set these types of igniters off, as they take a bit more current.
