My friends and I could never get any of the pointy darts to work with a hard throw--they never had the right balance not to loop or nosedive at high speed. What we settled on as the most satisfying to hurl is this design (found online widely under this name; requires letter proportion paper): https://www.instructables.com/The-Hammer-Paper-Airplane/ https://www.instructables.com/The-Hammer-Paper-Airplane/ Carefully made, it flies straight when yeeted without trimming, and the blunt nose handles landings without damage. I surmise that the fold along the entire edge of the wing contributes to high-speed performance by preventing the trailing edge from fluttering. Could this also be why the world record designs tend to have winglets? A design that's amusing to experiment with is the most minimalistic glider, made with a heavy roll-fold of the leading edge of the paper and three parallel folds forming the wings and fuselage.[1] The parameters being length & number of folds and camber of the wings, it can be tuned to manage a hard throw straight before stalling and leveling out to a long flight in phugoid motion. Flying rings are interesting, too. The rotationally symmetrical type formed from only a roll fold and tape (purity notwithstanding) are similarly minimalistic [1] like this without the winglets, thus a case against my theory of wing support: https://www.origamiway.com/plane-spy-plane.shtml https://www.origamiway.com/plane-spy-plane.shtml
