So I just built another airliner for a decent comeback. Wanna see how I built it?

Step 1. Determine the shape of the fuselage.

Recommended to use blueprint mod if you are building a replica.

Step 2. Nose section paneling.

Read this tutorial for details.
Here is an update though, be aware that the shape of the nose area does not always give you a circular shape, thus you should do CUSTOM PANELING if needed.

Step 3: Wings and Landing Gears

Follow blueprint as usual. Read this for wing flex information.

Step 4: Test flight

Please set up an accurate mass and a proper flight model before adding more details. Characteristics you should check:
1. Wing Area. Test your aircraft's takeoff and landing speed to demonstrate if it's fine.
2. Engine Power. Make sure your plane does not take off like a rocket!! Most planes on this site have this issue and I'm tired of it!
3. Drag. DECREASE DRAG, just do it. You know your plane's drag is proper when you can glide the plane to the ground safely from a default airport approach location. A narrow-body jet in this game should NOT have more drag points than 10,000.
4. Roll, Pitch, Yaw, Trim, Flap efficiency. This shouldn't be hard.

Step 5: Interior

I would recommend you build the interior detail separately from the main aircraft. It reduces a lot of lag and makes it easier to add parts. And it is a good strategy to scale it up 4 times.

Step 6: Combine

Pretty self-explanatory step.
Only use ONE attach point between your interiors and main fuselage. It enables you to nudge the whole interior out when needed.

Step 7: Final Check

Do you know that you can stretch your aircraft to make it a variant?

T to be tagged. Coming next week.

Vote for China eastern A319 or American A321 please!

I will only be uploading one of them, but the other variant would be uploaded as unlisted and you guys can download both.
