I am going to use a pair of these to control air starting up to 6 extra motors. When I am trying to get them all started ASAP (when boost detected), I am having some pause.
I have tested and am certain there are no issues firing two matches at the same time, but, If I set two channels with the same lighting criteria to light at the same time, I could actually be trying to light 4 at a time, which *seems* like more than I may want to ask from a small battery through the timer. Altus metrum default shows a 0.05 second firing duration to each e-match, so I was going to be slightly nicer to the battery by setting the second channel to be separated by 0.1 second or so. I'd like to be sure that when the electronics function, I haven't put them to use in a way that will cause a problem.
I can either put in a second battery, I can leave the delay in there to be sure I'm not reaching too far with the little timer, or both. Also, I am leaning toward ground starting two and eliminate the (potential) problem that way, or just fly a smaller number and have some redundant e-matches in empty cases for post flight inspection to see how they worked, or add another timer (yuck).
Is there a general practice here that most use? I may be concerned about a non-issue.
