Michael Dennis used a miniTimer3 to fire twenty igniters in his 12” diameter cone-style
rocket. A central J275R motor provided initial lift, and twenty E9 motors were successfully
airstarted using low power igniters, a high peak current capable battery, and the
high current miniTimer3 timer. Michael launched this rocket at the 2004 XPRS in
Black Rock, Nevada. You can see his ground test video on our Gallery page.
