I occasionally publish portions of the Belite assembly manual, which will help you build your very own ultralight airplane. Here we go with another installment:
Mating the Rear Fuselage to the pre-welded Aluminum
cabin
In this section, you are going to mate your rear riveted aluminum
fuselage to the cabin. This is done by
leveling both sections very carefully, trimming the length of the aluminum
longerons on the rear, and then riveting on gussets.
This isn’t too tough to do, let’s get going!
1. Level
the cabin and the rear fuselage. Using
blocks and a level, ensure that the top of the cabin is level. Although only one level is used in the photo,
make sure it is also level side to side.

| Figure 1 -- Level the cabin |
You’ll notice the small stubs pointing backwards on the
photo above, along the bottom of the fuselage.
Current production cabins no longer have the stubs.

2. Trim the longerons on the rear fuselage.
All four of the rear fuselage longerons are trimmed butt
flush to the cabin. Also, the top skin
will need some trimming to make it fit.
