I just got back from my weekend with Kasia in Gdańsk, Gdynia, Sopot and Hel. I thought I'd try to show Kasia why it takes so long to put one of these kits together using the front wing as an example.
The parts are all attached to a tree.

First, I use a pair of nail clippers to snip the parts from the tree.


Then these little plastic nubs are left on the parts

So, I grab a hobby knife and cut them down a little closer to the part

You can still see that a bit of these nubs remain

Then, now that it's much closer, I take a normal emory board that can be bought at any drug store, and file the part down smooth.


Now that the nubs have been filed smooth, I use a regular nail file that can also be bought at any drug store and use it to really polish the edges of the parts to remove any flash or scratches.

And now, one plane of the front wing is ready to be test fitted, but I'm not done with it yet.

I still have to repeat this process 5 more times for other components of the front wing.

Then, I test fit the parts, to check if they will need any modification before painting. As can be seen below, the main plane of the front wing that attaches to the nosecone is nowhere near straight. This would look really crooked on the finished model.

So I get out the emory board again, to file down one of the wing pilons that attach the front wing to the nosecone.

It's not exactly perfect in this picture, but I'm satisfied it will be straight to the eye when painted and assembled.

Next, I test the fit of the turning vanes that will go on the underside of the wing. I'm not gluing these on yet, because they will be painted black, while the rest of the wing will be painted white on the top and black underneath.

And then finally, I test fit all the wing components together with the endplates to make sure that they are straight. This assembly is now ready for painting, and I can move on to the next part assembly.

I recently picked up some tweezers to help in assembly of smaller parts

Total time: 16.5 h
