No one can conceive the variety of feelings which bore me onwards, like a hurricane, in the first enthusiasm of success. Life and death appeared to me ideal bounds, which I should first break through, and pour a torrent of light into our dark world. A new species would bless me as its creator and source; many happy and excellent natures would owe their being to me. No father could claim the gratitude of his child so completely as I should deserve theirs. ” – Victor Frankenstein (from Mary Shelley’s original novel).

That is exactly how I feel about my latest creation, the TallStein, or is it Steingeese? As I indicated last week, I’m kit-bashing the MG Sinanju Stein Ver ka and the MG Tallgeese into one giant monstrosity, as my side of a Build-off with Lupes of It’s a Gundaaam! As you can see, he’s already well on his way (to kicking my ass).

Now I get to reveal some of the modifications I am doing to my Stein but before I could do anything I had to wait for my parts to arrive.

When they arrived the first parts I grabbed were the armor for the side of the lower leg.

I picked up extras because I have decided to do away with those large side thrusters found on the Sinanju Mobile suits and go with a leaner look like that of the Tallgeese who doesn’t have anything down there. As the design for the construction of both the Sinanju legs is the same I only need to get two of these inner leg parts.

But it’s not as simple as just slapping them on because I want to be able to get access to this area.


I have plans for that circular frame part at the ankle so the, using the outer leg armor parts that I no longer need I did a couple of test modifications.

Starting with the easiest first I just hacked off the armor panel at the bottom. It definitely opens up the ankle area but also a little too much of the lower leg.

I voted no.

Using the second piece I created a line using a piece of tape. As this is a test piece I don’t have to be precise.

Cutting along that line game me this result.

This is much better than the first test, though still needs to be adjusted. I ended up trimming a little of the plastic off of the end.

With that settled, the hacking began in earnest.

Next up I turned my attention to this extra part I ordered.

I then cut it off the runner…

Oh no!

Just kidding. That was purely intentional.

Here’s a comparison shot of the side skirts of the Stein and the Tallgeese.

I want to use the Tallgeese’s side skirts on the big Stein because I think they will look good with minimal modifications. To get them onto the modified skirt frame piece I’ll use the very top frame section of the Tallgeese.

Test fitting for placement.


That white armor part is in the way. Something will need to be done about that.

Now a test fit onto the standing Stein.

It’s like… they belong.

As I expected the proportions don’t seem off thanks to the large skirt armors of the Stein.

So let the trimming, sanding, gluing commence!



I’ll just let that sit. Though that does mean Stein is looking a little odd.

And while I’m on the skirt, there’s this area that needs attention.

This section of the Tallgeese has a very unique feature.

That little sucker. Should be easy enough to get that onto the Stein.

I’ll just drill a hole here…

And then repeat that process twice before then removing more plastic with a knife.

Test fit.

Using camera trickery I can give an idea of how it will look when secured in place.

Probably the most significant modification I’ll be doing on the Tallstein will be to the backpack. We know the Tallgeese has a very distinct backpack unit and I wanted to incorporate it almost fully onto the Stein. So the first step is to trim away some plastic on a small, but important, piece.

When playing around trying to determine how exactly to make this work I realized that it could be accomplished if I use this small part properly, namely, getting it to fit here.

Trimming away the little bit of plastic allows it to sit almost flush on the side of the Stein’s backpack frame meaning all I need next is glue.

While it fit well after my modifications it still was an awkward position and I needed to clamp it place while the glue dried.

But it worked.


Once everything was dry I attached the arms from the Tallgeese and slapped the new backpack onto the Stein.

Then I attached the Tallgeese thrusters.

Not bad. Though quite large on the Tallgeese they seem not out of place on the Stein. I mean, look at this sexy backpack.

I’m still considered using more of Stein’s backpack parts on this guy but for now I’m satisfied.


Still more work to be done!

    The thrusters seem to be high up. They also look small and less imposing on the stein as compared to the tallgeese(duh..XD) In any case, they have asimilar effect to the GP01 FB..perhaps something below the backpack?

      I don’t think they’re too high up. I think in the last shot they look to be in a good spot. That said, I’ve still got some work to do on them and other areas to balance things out.

      • XZF says:

        Maybe the perspective in person is different. XD Anyway, looking forward to the result!

      • David says:

        it seems more reminiscent of the Hi-Nu, or something, with the backpack sticking upwards. (without funnels, of course.)

        nice job, they go together really well.

    I see that you’re incorporating the Tallgeese’s pelvic thruster. I never considered the possibility of taking that part of the Tallgeese and putting it on the waist of another unit, but I guess it works with some of them.

    I also can’t imagine how fast that thing would be with all of the Tallgeese’s rear thrusters in addition to a third of the Stein’s. However, that makes me a bit disappointed that the leg thrusters aren’t being used. If you really want to go with the idea of “unbelievably fast mobile suit” (although I’m pretty sure that isn’t what you’re going for) then you might want to consider putting the Stein’s “Wing” thrusters on the back of the legs or something.

    i cant believe youre doing this… this is awesome! i think im in love!

  4. Josh says:

    Are you going to add the Spartan Mohawk to it :O
    Plans to paint?

  5. David says:

    Where did you order the extra parts from?

  6. Ryan Edgar says:

    Loving the work so far Syd, i agree with others that the Tallgeese headpiece is a must on this kit. Are you going to give this kit the Tallgeese rifle and shield?

    Have just ordered the Armored Messiah Alto version and it should be here within a few weeks. I worked on the V Dash Victory Gundam during the Christmas break, amazing little kit. Looking forward to my Messiah tho, should be a very satisfying build 🙂
