A smart engineer would say “give me $100 and I can design you one with 5”StreuB1 : The upper fins have 4, not just 3 like the lower.
Marty DiBergi : Oh, I see. And most rockets only use 3 fins?
StreuB1 : Exactly.
Marty DiBergi : Does that mean it is any more stable?
StreuB1 : Well, it's one more, isn't it? It's not 3. You see, most blokes, you know, will be flying with 3. You're on 3 here, all the way up, all the way up, all the way up, you're on 3 on your fins. Where can you go from there? Where?
Marty DiBergi : I don't know.
StreuB1 : Nowhere. Exactly. What we do is, if we need that extra stability, you know what we do?
Marty DiBergi : Add a 4th fin?
StreuB1 : 4. Exactly. One more.
Marty DiBergi : Why don't you just make 3 fins a little bigger and optimize both the both the bottom and the top stage?
StreuB1 : [pause] But this one has 4.

For youngsters, search for 'it goes to 11' on youtube or similar if you have no clue what that's from (Movie: This is Spinal Tap, not other music stuff that might pop up).
I like the idea. Do it!!!
That's exactly what I was thinking!!And this would be a Fat Daddy?
Not a dumb question. Intuitively, yeah. Actually, not always.Stupid question though: Doesn't the lower stage require MORE fin area to be stable, or does it not matter?
