I am about to start building a two stage rocket, and in the designs I have the sustainer with a coupler that slots into the booster.
On a lot of two stage builds that I see on here, by some quite talented people, I see that they have the interstage where the booster has a coupler that slots into the sustainer.
Why are people doing it this way? It doesnt make sense to me. I thought that the open base of the sustainer would add a lot to the base drag, and that the coupler in the sustainer idea would reduce it and would allow the fins to be a little farther back.
I would love to hear peoples opinion on this. What are the advantages/disadvantages that you see in either design?
