I finished the engine by gluing the front half to the back half. Everything fit well and the completed engine mates with the engine pylon with no problems.

Continuing the engine build, the only major problem I had was the fit of the internal exhaust parts into the exterior exhaust shell. I ended up cutting off the bulkhead and trimming the internal parts until they fit properly. I then glued the internal side parts to the external shell, then...

I choose to build up the engine from the inside to the outside. Thus, I first made the internal intake and exhaust pieces. The internal exhaust cones have a bulkhead designed to be bent up to form the end pieces. It's best to cut these bulkheads off from the side pieces, and glue them back on...

The ailerons are pretty straight forward, but it looks like the design didn't take into account the thickness of the cardstock. If your paper has no thickness, I'm sure the parts would fit perfectly. But here in the real world, paper has thickness, so if you build the parts exactly as printed...

The outboard flaps are next, same problems as the inboard flaps and spoilers.

Today I found a major mistake in my build. When I built the wing, I thought the inboard section of the wing included a flap, and built it accordingly. However, what I thought was the flap, if inverted, is actually the inside walls of the flap well. I guess I will have eventually make another...

When I built the second wing, I glued the first three sections together before slipping them over the spar. This seems to create a straighter wing, but there is a gap around the landing gear wells when it is assembled. I then assembled the engine pylons and the flap actuators. None of these...

After completing the wing, the next project is the flaps and slats. Here's how they are supposed to look.

I've completed the basic structure of one wing. Lessons learned so far: The outer skin is glued directly to the wing spar outboard of the engine pylons. This means the spar must be built straight or the outer skin will have a warp. If I was to build this kit again, I would not use the tabs...

On my 737 design, the wing skins are joined together to form an envelope, which is then slipped over the wing spar and glued to the fuselage. No so on the PaperArts version. The wing is designed to have all it's flaps slats and spoilers out. As the photo above shows, there's not much wing...

Now comes the hard part, the wing skins and flaps.

Continuing the build, next on the agenda is the wing spars and skins. The wing spar is composed of a series of boxes glued together. The only end piece is at the wing root, so the boxes once glued together are able to twist a little. If I was to build another model, I would probably put some...

I don't think I'm such a fast builder. I still have a SMS Rhine/Mosel model that I started in 2000 which I haven't finished. Not to mention all the plastic models I have from 40 years ago. I'm picking up the speed on this kit so the momentum can carry me to the finish line.

Oops, hit the wrong buttons. Here are the photos.

Here's some photos of the horizontal stabs. My model in the background shows the additional details that could have been included in the PaperArts model. I've also included some photos of the real stabs so you can see the details. I hate to nit-pick, but once again this is an area that could...

Today's installment is the horizontal and vertical stabs. All three surfaces are built using the same technique. Basically there are the outer skins, an internal box spar, and an end piece to give it the right airfoil shape. All three surfaces are designed to fold at the trailing edge, and...

I thought I would post a photo showing the difference between the PaperArts model and my own. The PaperArts version is much more advanced. I also wanted to show how I join the fuselage tubes. I smear a bead of glue around the piece without the tabs, bend the tabs inward, then join the two...

Today was spent in building the back half of the fuselage. I started at the tail end, and worked forward. Some of my comments on this review may seem negative, but they are not meant to be. I'm just commenting on things as I build. Overall, this is a very detailed model, and the fact that...

Here's a better photo of how the fuselage over the window is crooked. Also, a photo of the completed fuselage so far. From this point, I'm going to build from the tail forward. It is easier to fit the fuselage tubes from small to large and part 15 is the widest fuselage section. Also, the...

I got up early today and completed the fuselage through parts 15. Just a matter of making paper tubes and gluing them together. My only real complaint is that there should have been a center line printed on the bulkheads. If you don't get them lined up correctly, the fuselage will lean to one...
