In the meantime, I realize that the openings of the funnel parts
must still point upwards on each side.
Good close-up photos have convinced me.

Excellent work so far. Not to be pedantic, but the concern over the angle of the RCS thrusters on the model is academic because they should be covered. When the shuttle stack was on the pad, all RCS thruster openings (forward and aft) were covered with Tyvek covers to keep out foreign objects and rain. The air pressure of launch usually blew them off; any that remained on after launch were blown out when the thrusters fired.

For example, they seem to have reversed the colors on the RS-25s (formerly known as the Space Shuttle Main Engines, or SSMEs). The expansion nozzle should be a dark metallic color, while the eight longitudinal "hatbands," as they are sometimes called, should be a lighter metallic color.

It's not really wrong. It may be a bit exaggerated, but the bands are usually darker than the engine bell. There's plenty of photographic evidence over the course of the shuttle program that supports this. Some images below.

On the other hand….

well, they are both right ...

the reality is that NOTHING is black. They are different "gray" scales ... I would even tell you that it is dark brown, (or very dark green)

also ... it depends on:
1- the mission that I am trying to recreate ... if it is very old ... YOU WILL change the materials used in the engines (the cooling tubes) ... comparing them with the new ones ...
(Look at the most modern SSME, they seem of different material)
(or from the SLS rocket)

2- the mission stage: during assembly in the VAB, before takeoff, during launch or landing ... in those cases you can see: naked (no blankets on the vab), clean (pre-launch), "frozen" (take off), and dirty (after atmospheric re-entry)

Even ... I would tell you that cryogenic vapor ... creates ice shells on the surface ... which makes it change color.
... it is also true that during take-off ... the SRBs powerfully illuminate all surfaces ... and maybe that's why (cryo ice) looks pale as well.

... maybe, in the photos of dhanners, the engines are in the VAB, or engine models ... I have even seen and there are photos of the engines with clear grey tubes ... but they are in the vab, prior to launch (two things could have happened: either they were covered with blankets ... or the ignition and intensive use changed their color ...)

something is certain, they are not black.

I would like to recommend (as a curiosity) to see the axm MORENO model ... it is NOT black ... it is very dark gray ... and BROWN, in addition to dark green inside. (tubes are clear)
this model seems to coincide with the photographs of the engines when they RETURN to ground (more dirty)


the photos that I put here, keep in mind that they are in different stages of the mission (vab, launch, space, landing) ... and ALSO they are of different missions (old and new)

Hello, dhanners, Rambler and craft!

I can only follow your discussion about the engines with thanks.
I myself am only a simple model builder, who has hardly any idea about the
details of the shuttles.
This model sheet is the second of a space shuttle I have under the knife.
The first one was from HOBBY MODELL around scale 1:72.
This 1:33 scale model by L. Cherkashin attracted me because of the enormous size of the model.
the enormous size of the model. Also the detailing here has a higher degree.

Thanks for the information and great pictures.

You're doing great work, Adolf, and there will always be "rivet counters" in the hobby. I'll admit when it comes to the Shuttle (and X-15...) I'm a rivet counter. My comments are not directed at your skills, which are proving -- yet again on this model -- to be among the best in the hobby.

I've built some of Leo's models before and always found them to be well-researched and expertly engineered. They are also generally very accurate in design, colors and markings. It's just that to this rivet counter (who has spent a fair amount of time over the years researching and modeling the Shuttle in card and styrene) I think he missed a thing or two. The issues seem magnified in 1/33rd scale.

Today, the construction of the bow section of the shuttle is completed.

The construction of the middle part of the shuttle - the "cargo hold" - will continue soon.

don't worry ... it looks great ...
It also happens to me (with racing cars ... rivet counter..especially when it is a specific car..of a specific race of a specific year)

something I noticed ... is that the main landing gear caps are missing ... something missing? (under the nose)

Your model looks excellent ... here I just want to say that (it's not your mistake) it seems longer than usual ... or is it just my vision? (long nose)

[A. Pirling]

As for the length of the bow section, I can only recommend,
wait until the very large cardboard model is finished.
At the moment, you can only see about a fifth of it.
In addition, the wide-angle shots of the smartphone can easily cause
the object depicted is easily shortened or lengthened.

Greetings

Adolf
