I have a really cool idea for a rock I want to build, but I have no clue how to do some stuff for it. What I want to build is a 24 in long (at most) rocket, that will fly on a b/c engine. But what makes it cool is that when the main engine has completed the burn cycle, it will ignite these three little rockets (1/2 or 1/4 A's) that will fly up, and then streamer down with the big rocket. How would I do such a thing?
Oh, and some backround, I am very profecient with rockets. I have build a few level 3's, and a rocket from scratch, so I can understand what you are talking about.
