A tutorial? Aren't you the guy that still uses default wings?
Yes. But I think I still have some experience that can help new people get into building fighter jets. More specifically, I mean twin-engine generation 3/4 fighter jets that have fuselages that aren't just highly advanced tubes. (Sorry, F-16.)

Moving on...

For the purposes of this tutorial, let's look at 3 aircraft in order of increasing difficulty to build, in my opinion.

The Su-27 Flanker,

F-15 Eagle,

and F-14 Tomcat.

DISCLAIMER: I am not an aeronautical engineer and I cannot gaurantee the correct usage of any terminology. I'm also not nearly as clever as one.

A universal tip I can give is to break the aircraft up into sections. Typically, with most twin-engine fighter jets, you can seperate it into a nose section, engine/intake section, main body section. (Not counting the cockpit, because it's obvious.) Of course, there are SEVERAL exceptions.

Su-27 Flanker

I've color coded the fuselage here: The nose section is red, the engine/intake section, blue, and the main body orange. (Some other bits are those colors too, but I think you can tell what's what.)

The reason I say the Su-27 is the easiest one is because it has one of the most pronounced nose and engine sections of fighter jets. It's very easy to differentiate them just by looking at it. You can even easily see how the nose section continues down the length of the aircraft, almost like a spine, but stays visually distinct from the main body.

The main challenge, however, is the transition from the nose to the body at the front, which is very smooth and curved. I've highlighted this part in a different shade of orange and it uses hollow fuselages with ~50% left/right cut and ~50% top cut to achieve a low part, but perfect curve.

Then, there's the rear section. The green section from earlier must be blended with the main fuselage, which I've done here using this yellow piece. (It looks better with the horizontal stabilizer, but the wings are removed for clarity.)

F-15 Eagle

Next up, the flying tennis court. Same deal, the nose is red, the engine/intakes blue, and the main body orange. This is more difficult than the Su-27 because the F-15's engine and body are more blended together.

But, by looking at the bottom, we can more clearly see how the engine/intake section is sperate from the main body.

And like the Su-27, there is a section (green) that originates from the front and continues to the rear, upon which the horizontal and vertical stabilizers are placed. And again, it must be blended with the main body. I've also made the top half (cyan) of the engines different from the bottom half to achieve the shape, which was also done on the Su-27, but not as much.

But unlike the Su-27, the main body must also be blended with the intakes, which can be seen here as it transitions from orange to blue near the front.

F-14 Tomcat

This. Plane. Will. Drive. You. Insane. (If you try to make it accurate.) The sections are pronounced, but the section above the intakes (pink) must be a seperate section. This is the most difficult part to make on the F-14, but once you get past this, the build becomes easier.

Here, you can see how the nose section blends with the orange section of the fuselage. Speaking of the nose, I've used a technique where the bottom and top half are seperate, which allowed me to get a sort of egg-shaped cross section. Having it as one circular top and smooth bottom section makes the bottom too curved. It's a very versatile technique that I also used on my F-86 and Me-262.

And here's the rear section. Not really much to talk about here though. There's a section along the side (green) and the top is shaped using a seperate section (cyan) like the others.

Oh, and you also need to have sweeping wings. Have fun with that.

Not really sure how helpful this was, but this is how I go about building these awkward fuselages. And I hope more people go out and try and build these planes. When you make a fighter jet, break it up into sections that can be made with SP fuselages, figure out how these sections transition into each other, and hopefully you get something that looks nice. Oh, and use fuselage cutting. A lot.

And if you do it right, you'll have something elegantly contructed and maybe even low part count. You could even call it: simple.
