- Reaction score
I have a few E9-8 motors and I was thinking about sticking three of them in parallel into a rocket. However, the motors all have ejection charges. I'm wondering how exact the time from ignition to the ejection charge is. What's the uncertainty in those? Because if they all fire at approximately the same instant it should work fine, but if not there could be a problem. Thanks.
