"Luck Runs Out" High Power Rockets out at BlackRock First HP cluster First air-start / cluster First on-board video 7-1/2' tall, 4" dia. four motors, two computers, two timers, one camera This rocket will eventually be the second stage...
Why did yo have two timers? Is one for the staging and the other for the airstarts? What batteries did you use for the airstarts? Did you use Thermite?
One for the 2-38mm & one for the 2-29mm. Used Duricell 9v.
No Thermite, home dipped low current ematch & chunks of Blue thunder painted to the core. I feel safe using one timer for 2 motors only, the battury is pritty well spent with two ematches. The first flight I used 1 timer for each 29mm but in the 2 stage mode they will need to light 2 motors each.
This rocket is the upper stage, the first stage is under const. & will be 98mm with a L952W for first flight then lighting (2)J570's then (2)I200's. But to answer your question for this flight it lifted off with (2)J350's & air-started (2)I200's.

Two timers yes. Both for airstarts.
One for the 2-38mm & one for the 2-29mm. Used Duricell 9v.
