Some form of SU-27 probably
thingiverse
A some-form-of-SU-27 model I made... The aerodynamic centers and the neutral point are marked just like https://www.thingiverse.com/thing:5352640/comments#comment-6435165 and with some tweaks in setting you can probably balance it. The dot in the front (that's actually a CG sign) is the CG location required to properly balance it. If you wonder why it says no moving tails, I was intending to build one with rotatable tails so you can twist them to balance the plane at different speeds, but that turned out to make the tails hazardously fragile so I just fixed them flat. Sadly that means the balance speed is very high. You can download the stl and do, in Prusaslicer, right click -> split -> split as objects to get everything on the bed, or download the already set-up 3mf file. *DISCLAIMER*: This plane is here strictly for it's cool. No political stands are inferred and please do not introduce political topics in this post.
