Great job, very detailed!

I'm too lazy to make that diamond shape, but I did make a new version of my own design, which should have better stealth characteristics.

Thanks for the input. I've made a bigger version that has 1,5 MKII cargo bays worth of internal payload. I also removed the rudder, burried the engine deeper and made sure all surfaces are angled. Speed at sea level is worse ("only" 1000 m/s instead of 1600 m/s) and it's a lot bulkier than the previous model (I like small planes), but manoeuvrability is still good.

Here's my take on the 6th generation fighter theme: a hypersonic drone (that's supposedly stealthy).

I haven't been very productive lately, except for some stupid stunts around the Space Center such as this one: I have a bunch of replica's that are pretty much ready to release, but I'm too lazy to write up a post. I also can't stop trying to tweak them performance-wise so they feel somewhat realistic. (The planes awaiting release are: A-10 Warthog, SU-27 Flanker, F-15 Eagle, Mirage 2000, SU-25, MIG-21, F-5, Saab Viggen, F-16 and AV8 Harrier)

I changed the pitot tube of my Mig-21 to something that won't break off. I also clipped in counter-productive control surfaces, to imitate stalls when pitching up hard. (clipping isn't cheating if it's meant to decrease the performance, right?) I'm now more likely to slam into the ground or other objects, but performance is still good enough:

Great job, now I feel the urge to further tweak my own MIG-21. Do you mind if I lend your idea of clipping the engine with a circular intake?

Very impressive. Would you mind giving us a peek what the craft looks like? Do you use some kind of ejection seat to get the kerbal out of the vehicle?

Please disregard my pathetic sub-600 m/s attempts. 618 m/s is my new record. Special thanks to Jeb, who had to make some compromises on cockpit comfort; that 35G brake must have hurt in that command seat I wonder if we could surpass 700 m/s.

I improved my speed to 512 m/s. Feel free to disregard my puny first attempt. I feel like I also deserve bonus style points for how ridiculously close that braking was :p. https://gfycat.com/LikableWelltodoHornet

First attempt with embarrasingly slow sub-500 m/s speed in the spoiler:

I'll bite. This one should fit all the requirements, except I didn't add canards. I added red stars for bonus points. craft file here Ejection seat in action:

Yup, small planes can do stunts that you can't even imagine doing with bigger jets.
