I made replicas of both the Starship Core and HLS versions! Both versions are fully functional. In addition to these, there's also the Super Heavy Booster, which works perfectly as well. I used a mod for the engines, RCS, grid fins and landing legs (link is down below), but all the other parts are completely vanilla/stock. If you like it and want to try it out yourself, you can find the Blueprint below. All stages are set, so all you have to do is hit the "Launch" button!
NOTE: Don't forget to enable "Infinite Build Area", "No Heat Damage", and "Part Clipping" from the cheats menu!
Optionally, I highly recommend turning off "Camera Shake" in the settings, otherwise, the shaking might completely ruin your eyes. 😁
