yup, it is a 60%I.
Getting them all started? Not a problem, really, the flash pan works really well.
Will they cato? .... that is another story.

I would not recomend flash in the pan . Its not that many motors just wire them upwith a big clip whip. And glue the **** out of the motors.
If you wire them in parallel, which is how most clip whips are wired, you must multiply the current necessary to light one igniter times 19, the number of motors to be lit.
Robert Briody's report on igniter currents showed Estes igniters using 12 amps each.

I don't know what current Estes igniters require, but if it's 12 amps each then you're looking at 228 amps. That requires a pretty substantial launch system.
People who do large clusters usually wire in series or do flash in the pan ignition.
I launched 241 estes d-12 and 9 c-6 motors cluster with flash in the pan. Thats how I know its not reliable.16" sonotube stuffed with as many motors as I could fit. 1 1/2 lbs black powder and a bunch aluninum and titanium powder about 80 percent lit right away 10 acouple seconds later. 12 never lit.

That's impressive! I would have enjoyed seeing it.
