Vostok R-7 ICBM Soyuz Model rocket

I downsized the blueprint to about 1/44th scale, and now it stands at a height of one meter. When you look through the list of files, you'll see various assembly options available - just pick the one that works best for your printer. I built this model with four A motors and one C motor in mind. After numerically calculating its center of gravity, I found it to be quite stable overall. So far, I've only managed to get it airborne once, but even then, it only reached an altitude of about four meters before coming back down - clearly underpowered! Eventually, I plan on printing new conical liquid boosters that can accommodate larger motors. Honestly, I'm happy just having it safely sitting on my desk instead of trying to fly it again!
