This sale includes the STL files for all the 3D printed parts as well as fin templates to build a semi-scale model of the P-270 Moskit (SS-N-22 Sunburn) Ramjet Anti-Ship Cruise Missile: https://en.wikipedia.org/wiki/P-270_Moskit -- I am asking $8.50 for the STL files. Please message me and I will share paypal info and will send a .Zip file with STLs and some build notes once payment comes through. Buyers get rights to use the files to print the various versions of the rocket as many times as they want but I do ask that you not resell the rockets or distribute the STL files to others. I am also happy to make tweaks if you encounter problems or have feedback.
This model winds up being just over 21" long w/ 145mm front BT60, 110mm BT55 & BT20 ramjet tubes, and 85mm rear BT60 tube. STLs include nose cone, front and rear transition sections (from BT60 to BT55 + 4x BT20 tubes), rear square ramjet slotted for rear fin (longer or shorter slot options), and engine mounts. No need to cut BT20 tubes longways, I designed this to let you leave them whole (I used scraps of cardstock, from Viking kits, to square off ramjets but you can also use thin balsa or basswood - I included tabs to help get these pieces in the right place at correct angle and used some wood filler to smooth things out). I am not good at finishing so just prime my models but I am sure this would be even more beautiful if you are good at finishing.
I launched on C5-3 Super C engine and it was very stable without any nose weight added - video included below. I will add 24x95mm engine mount option and D-to-E adapter and include in .ZIP. Note: For my P-270 model I moved the large fins to the rear and small fins to middle (prototype has large fins in middle and small in rear) but model should be stable with the large fins where they belong in the middle (especially with a bit of nose weight). It simmed stable in OR w/ large fins in middle but I went with more conservative design for my first build.
