Since composites burn from the top down and the delay charge is burning at the same time as the thrust charge, is the delay time the time from ignition to ejection, or do they add a little extra delay to account for thrust time, making the delay end of thrust to ejection (like Estes)?
Just wondering, a rocket can travel pretty far at terminal speed in one sec! But I guess it would be more of a reverse effect, the ejection is going to come a sec early on a composite versus the same time delay as a BP engine.
