Make your own composite starters. We supply the wire and chemicals, you supply the acetone and labor. Make up to 240 composite starters. Requires 12 volts to fire, and the wires have a chip for precise chemical separation. The chips are .15"/3.8mm width where soldered to the wires, so please make sure they will fit in your motors. The base of the chip can be trimmed before dipping to fit smaller throats, or can be removed all together. Just make sure the copper leads don't touch, or aren't too far apart as the mix is conductive.
