The Estes Pro Series II Sonic Igniters are designed to work with Estes and Aerotech E- to G-class composite model rocket engines. The Sonic Igniters are 9" long, two-wire igniters with a slim, pyrogen-coated tip for positive ignition. Although these igniters will work with most 6v to 12v launch controllers, they are perfectly paired to the Heavenly Hobbies' Lightsword 12v launch controller.
