The fuselage is a simple set of rounded cross sectional pieces.
parts
disks
Note:
For whatever reason, this one as well as some other of MaksArt models have no glue tabs in the axial direction ( front to back ). However, those are straight pieces and easily made.
When gluing the tabs for open section around the cockpit opening, make sure you orient them properly. But in reality the parts are all round, so it makes no difference.
Here is the center section with the cutouts for the main gear wells.
And all the rolled sections ready
