Solid Rocket Booster Realistic Flame-Out Test

I've been thinking about this for a bit now. If you watch Space Shuttle launches, you'll notice that even when the SRB's experience flame-out, and are detached, there is still leftover fuel being burnt. So, after several tests and revisions, I got to a place where I am happy with the results. It's not quite perfect, but it is only with the visuals, and no one can really control that. If you want a tutorial, please let me know in the comments section below, and I'll do it if there is popular demand.

The mod RealFuels (I believe that's the one) introduces a thrust curve like that for SRBs, quite fun!

Man I wish I came up with this because most of my low kerbin orbit spacecraft use this SRB as first stage

I think i know how you did this, and I gotta say, big brain move

Hmm, did you clip small SRB inside? Or is that a mod?

[Tkia_]

i'd say 40% less fuel in the SRB you've clipped inside

I think there's an RO mod that does this? I forgot but they're called residuals

I think it would be more realistic if you tilt the smaller srb nozzle up

At first I thought it was a kal-1000 lol
