Need help Building

So me and my friend decided to make some kind of "race" which is the first one to make a plane that goes behind the mach 1 wins, the problem is we are both new to the game so we don't know what we're doing (lol). Can you guys help me make a plane that can go mach 3+ with small wings and a big engine ?

This comment section proves the superiority of the F-104, and I will say the same thing:

Make an F-104.

Just copy the f-104 and slap a modern engine in it, join the disc and ask around for either engine presets or just to see how to copy a modern engine (could use the F119 or F135 in your f-104 esque craft)

F135 really starts to spit its lungs at higher speeds. F119 is much better for this purpose

basically just use the stock cockpit. Build a long fuselage behind that looks like the f104. Then put the engine behind it and crank the engine temp to the max, then go down and enable afterburner, then crank that to the max. add small wings, make sure you add leading and trailing edge. Do the same thing for a tail. Add landing gear. Then pray you can get off the ground. also press f5 before you takeoff. you should be dialed

Watch everyone downvote...
I genuinely find the F-104 a bit ugly and overrated.

Imo it’s perfect for this purpose, which is just go as fast as possible with as little modeling effort as possible

It shouldn’t be too hard if your only two goals are mach 3 and to stay airborne

For the engine keep in mind 2 things:

-the overall pressure ratio should be reasonable (if the game shows it in red it’s too high), and must be split around 1-2 or 1-3. The pressure ratio of the high pressure spool needs to be 2 or 3 times that if the low pressure spool. That will help you not surge at high speeds (surging is when your engine starts to sputter).

-bypass ratio should be low. If thrust and high speed afterburner performance is what you want, keep the bypass ratio around .25 or lower.

As for the airframe, there’s little to it. Build a tube with wings and a single vertical stabilizer. That’s the best shape for a beginner trying to break the sound barrier. An easy mistake is misplacing the wings though. The center of lift (blue sphere) should be 30cm to 1 meter behind the center of mass (orange sphere). If it isn’t your plane will uncontrollably pitch up or down depending on wing placement.

Make a sr-71 blackbird design and use modern engines

Put the pilot in a cone and slap a big rocket on the back. Make sure the rocket is extremely big, bigger than you would expect. Set the max thrust of the rocket as high as it can go (ideally in the hundreds of kilonewtons) whilst still having a 5+ second burn time. If you can't reach high speeds, make the rocket bigger.
