Here is my entry. I tried making a teeny tiny little ssto, but it's pretty difficult without lots of part clipping, and I'm not really a fan of that. So here is the WASP instead: Wasp-SSTO by killakrust on Sketchfab It weighs in at 6.6t (recon I could shave a bit more off by removing more oxidiser). It's a variation of an SSTO I designed ages ago, and was a lot easier to get into orbit prior to the new aero, so it's a bit bigger now. Because it is so light the flight profile is pretty easy; just point her to 45degrees till about 6-7km altitude, then push the nose down to 30 degrees and ride it out. Here is a video of Valentina taking it for a spin to AP 81148 / PE 79066, then returning to the KSC runway.
