Welcome aboard!

Is that an old HP 15C? I loved mine -- especially when students would ask to borrow my calculator, then come back a minute later because they had no clue about RPN. 😂 I sold it on eBay a few years later to a Japanese engineer working in Saudi Arabia.

Ah, the ol' Witwenmacher! 😉

Here's something you don't like to see in your laser-cut frames set: That's a lot of slop in that fit there (not glued yet), and it doesn't help that the kit has only a single wing-length spar, so there's further potential for misalignment inherent in the design. It's little things like this that signal the kit being a step down from say, oh -- a Halinski kit. But hey -- it's also much cheaper than a Halinski kit, so there's that.

The dorsal hump behind the cockpit is no walk in the park. If you look closely at the internal frames, you'll see that there's multiple curves and sharp angles. There were also no joiner strips in the kit, so I added some from 20# bond. I assembled the hump off the model. And here's the final result, which didn't turn out too bad IMO.

Which is part of the reason I choose to build in card. As much as I marvel at the realism achieved by some of our plastic modeler friends, I know it would take a long time and many less than satisfactory efforts to even approach that level of skill.

Internal framing for the horizontal stabilizers added; skins cut out. Scratch-made joiner strips added. And voilà! Empennage completed.

Congratulations on your award!

Vertical stabilizer added. I opted not to go for separate control surfaces.

I have a very dim recollection that this might be a browser issue, but someone else will need to confirm that for me.

At this point, it was safe to open up the cockpit again.

Surgery Here's the start of the left wing root repair. And the finished repair -- maybe. On to the right side. And the finished right side. Since this gap went right through one of the green splotches, I had to fix that as well. I rather liked the effect -- it camouflages the repair -- a little. So I decided to add some splotchiness to the left side. As usual, this looks better in real life and when one isn't deliberately looking for it. I can move forward now!

Very nice result! Congratulations!

Well, I'm just having fit issues all over this model. As usual, I never quite know for certain whether these are due to my efforts or to inherent design issues (but I will observe that so far I have only successfully completed one out of three attempts at models designed by Mr. Paczynski). As you can see in this photo, the upper and lower parts of the fillets, which are NOT separate pieces in this kit, are not going to come together neatly at the aft end of each wing. Some substantial surgery will be needed. I think this model is going to be more of an "artistic representation" than normal.

That is very nice indeed!

Well, as hinted at in an earlier post, the skinning of the forward fuselage poses quite the challenge. First we have the bottom skin added to the cockpit/fuselage frames: Then the forward skins added -- the front part is not glued down yet in this photo. As you can see, this structure is going to have a few gaps to repair. It also has, despite my best efforts, a little bit of 'starving cow' action going on, but the camouflage scheme hides it pretty good. To repeat what I said earlier, this is a very unusual fuselage + fillet design. I can't say I'm too fond of it. Having said that, this same model will probably turn up on one of the Polish forums looking like an absolute work of art and free of any errors! 😂

Very nice work, Geordy! Is the model completed, or is there still some work to be done?

Nicely done! Congratulations!

Since completing the forward fuselage looks a little intimidating, I decided to work on the rest of the fuselage first.

That's a really nice presentation, Jeff!

Beautifully done! Congratulations!

Giving this topic a bump after reviewing all 22 pages in this section. Please remember that the ONLY tag we use in this area is the word 'done' to indicate completed builds. No other tags are permitted. Thanks!

I have formed and glued together the front two fuselage skins. After dampening the forward opening, I temporarily inserted bulkhead A to help the skin dry into the proper shape.

Hmmm. 🤔 Might not be a bad idea. Of course, I don't have any balsa here, and the horse has already left the barn, but it might be something to keep in mind if I ever run into this again.

Okay, folks, here's an unpleasant lesson in card model designing. This particular design element is something I did not know about this kit in advance of its purchase. The outlined portion of this photo indicates the location of a wing fillet. I have done enough wing fillets now that they no longer intimidate me like they did back in the beginning. But this kit does fillets in a completely different fashion. In most kits, the fuselage is a roughly cylindrical structure coupled to a more or less straight wing, as indicated by the dashed lines in the photo. The fillet (solid line) is then added as a separate piece. But not this time. This brings us to the external cockpit skin (the inner skin posed its own set of difficulties -- I cut it into left and right halves to facilitate assembly, and the left half took three tries to get it on right). Here you can see that the fillet, instead of being a separate piece, is an integral part of the skin. This made shaping the skin quite a challenge, because first we have the inward curve of the fuselage, then the outward curve of the fillet. And to complicate things even further, the radius of each curve changes from fore to aft. 🙄 After much fiddling around and test fitting, I decided that trying to glue this skin on in one step was going to be a nightmare, so I started by tacking the left and right edges to their respective wing frames, which ensured the alignment of the piece (hopefully). At this stage, you can see that there was still plenty of slack to be taken up at both the back . . . . . . and front of the skin. I then glued the front of the skin down, making sure the front and rear tick marks were lined up and pinching the skin down over its frames to eliminate the slack. I did not glue the rear down yet, as I want to see how the next skin aft fits before securing it. The kit numbering suggests that the next skin forward is the next step of the construction sequence. The dashed line indicates the fillet that would be a separate piece in 99% of the card modeling world. The shaping of this part adds another challenge as the shape of the fuselage changes from cylindrical aft to a more squarish cross-section forward. That's it for now!
