Could you please tell us (for reference) what size is (in centimeters) THE BASE of the OMS motor (the tiny little circle where the OMS motor is supported / attached)??

It is one of my biggest problems, the smallest pieces, they fall apart in my hands ... simply deformed to death. that's why I don't make VERY detailed models on a small scale (even my lancia had to resize it)

Dear craft!
The OMS motor is supported by cylindric base d=5.622 mm.

Rudder - Airbrakes

It took me a while to understand,
that there are two flaps vertically mounted on the vertical stabilizer.
Right and left flaps are movably mounted on the tailplane,
Both extended at the same time, they serve - so I assume - also as airbrakes
when the orbiter lands on the ground.

[A. Pirling]

Special attention is to be paid again
that you clearly assign the components of the right and left flap.
With a little feeling when moving the flaps can be opened and closed quite well.

Catching up on all the posts, and I have to say your model is coming along nicely and looks great! Pretty cool the speed brakes actually deploy.

Scare in the evening hour

I was just about to edit new pictures,
I was shocked to discover
that for some inexplicable reason an entire subfolder of the Discovery
had disappeared without a trace.
A grueling search began. Fragments of the folder I could bring back to life from the "trash".
No idea how they had gotten there.
Other parts were fortunately on a recently made backup copy.

Nevertheless, unfortunately, many files were lost.
Among them were scans of parts I had made before I started working on the model.

How good that I had already changed the parts for the cockpit windows before the loss.

Now the frames of the windows correspond better to the original.

I have ordered aluminum wire for the cooling tubes on the engines.
Until that is delivered, I'll start building the wings.
The interior - i.e. the bulkheads - consists again of a huge number of
of laser cut parts. At first I collected them in two plastic envelopes -
right side - left side.
Then began an extensive 3 D - puzzle.
I can only advise here not to build simply on it.
If you assemble the profiles beforehand, some of the profiles can only be
can only be attached very awkwardly.
Hopefully I have correctly aligned the formers at the edges of the wings.
the edges of the wings correctly.
On some of them thin lines are burned in, only,
where these should point now, whether to the front or to the back ,
was not quite clear to me until the end.
Hopefully my approach will not result in uncorrectable errors!

The skeletons of the wings should now get their skin.

A look at the components W 01 to W 11 and the undersides W O 1a
( two sides for each wing) already gives an idea of the construction.
I would like to emphasize that the designer uses arrows, small red numbers and
boxes to indicate how individual components should be glued together before attaching them to the skeleton. If you follow these indications, you will succeed in getting the outer skin well attached to and around the skeleton.
To give the components a better hold at the edges and at the transitions from one component to the next, I glued narrow white or black strips at the corresponding places. It has not been shown that the dimensions are no longer exactly correct as a result.
And again, I like to repeat myself, I am thrilled by the accuracy of fit of the construction.

[A. Pirling]

I started with the right wing.
I started with part W 01, to which I glued parts W 07a and W 0 7.
It is important to note that all components, starting with W 0 2 to W 11, must be preformed
must be preformed very well so that they later fit snugly around the skeleton's formers.

Since component W 0 7a is particularly long, it must be preformed with special care.

And this is how to proceed:

First, align W 0 1 - the white upper surface of the right wing - with the left and rear edges of the skeleton.
skeleton and glue it in place. Then draw the curves of W 0 7a and W 0 7 around the
the curves of the formers and glue them in place.
Now you can glue W 02 with its parts W 08 to W 11 on and around the skeleton in a similar way.
skeleton.
This is followed by parts W 03 and W 04.
W05 is not attached until the wing is attached to the hold.

[A. Pirling]

Now you can turn the whole thing upside down so that the underside is facing upwards.
The main surface - W 01a - is aligned and fastened first.
Then it's the turn of component W 0 2a. It closes the remaining surface with a perfect remaining surface.
Finally, W 06 is attached to the rear edge.

When I had finished building both wings
once again I had to do a test with all the components of the orbiter I had built so far.
Here are the pictures.
