Can you please let me know the suggestions to improve the Saturn V? I am presently building it and although just started and only about 7 sections are ready, it there is room for improvement, I would like to know. Thanks

For those of you who are building the Saturn V in 1/48 scale to remember this year's 50th. anniversary of humankind's greatest achievement, I have a beautiful highly detailed model of the LEM that I downloaded (legally, as far as I know read the enclosed sheet) several years ago and I think it is a much better model for such a big and beautiful rocket. Even more if David's LUT is used. PM me and I'll send it.
Pete

I downloaded this model not from any pirate page and about 12 years ago. So I cannot provide any permissions because I don't know who published the model. If I have to follow rules and be banned from the forum, I'll accept it, no problem. Thanks for your help on this matter, but rules are rules and they have to be followed. I just wanted to help.

Assuming it is the Greelt model you are building (which is what my model is based on) here is what I have found. First the updates in the download section of this model are important. Once you have them then:- F-1 engines are perfect Stage one is perfect. Interstage 1 to 2 is perfect J-2 engines are perfect Stage 2: There is a thrust structure issue with this being too big (in terms of depth) to fit into the interstage with the stage 2 engines attached. There is a work around by modifying the parts given in this thread. However an improvement would be parts that work without modification. A second point is there is no designed "join" for the J-2 engines to the "cross beam" of the thrust structure of stage 2. I think (and it is just my opinion) that this cross beam area would greatly benefit from a complete design "improvement" that full incorporates the J-2 engines, the cross beam and the LH2/LOX pipework. that would make it as "polished" as the stage one engine area. I realize this is really easy to say but a lot of work for a designer (which I am not). Personally I also found it better to do the umbilical tunnel and pipe fairings etc on the outside of stage two in the same method as the umbilical tunnel on stage one. Interstage 2-3. This would really improve if the "inside" of it had a design in the style of interstage 1-2 (which is pretty incredible I think). This would be an intricate number of struts and curves but one advantage is that (I think) they would all be just white card. But it still a huge amount of work to work all this out. Stage 3. A small point is there is no "designed" way of joining the J-2 engine to the thrust structure but that certainly has a strightforward work around. On a personal note I preferred to make a more "box shaped" umbilical tunnel than the one that came with the model (details in this thread). Also the silver fairing for the aux propulsion systems could be made more "curvy" Finally if you are going to add the Instrument Unit you need to decide if it is going to be "fixed" to stage 3 or a separate detachable piece. If the latter then you need to some way to connect the top of stage 3 to the IU to the SLA. A simple (but bit ugly) method is given in this thread. IU: This part would be greatly improved if the inside, instead of being a printed graphic, was instead a 3d model. It would be very intricate. SLA An improvement would be to have the "craddle" (at the bottom) that supported the LM LM is perfect SM I found a bit of "on your own" on how the main engine joins the main body. I guess some people would say an improvement would be having an openable 3d SIM bay CM The docking mechanism is a bit "on your own" and I think could be improved design-wise. BPC I found it needs to be slightly enlarged to fit properly over the CM. However that may well be due to not making the CM and/or BCP well enough LES is perfect Finally just to say that when I say "improvements" it is not meant as a criticism of the current designers. The current model is wonderful, these are just ways it could be tweaked to be even better. Hope this helps Regards Kevin

@ Petestein
That looks like the LEM from U-Don. I'm working on it myself, hence the familiarity with the model. It's legit and is available here U-DON'S FACTORY If you search the forums here you'll also find some build logs of the same.

U-Don's LEM is a fantastic kit! It turns out beautiful. But if I ever do it again, I will print the windows on vellum.
 My aborted 1:48 Saturn V first stage is along side. I couldn't prevent warping of the side walls of the stage so I trashed everything except the thrust structure: And the odd F-1

What goes against the forum practices is to offer to re-distribute a kit by any means (publicly or privately) without the designer's explicit permission.
