According the build manual you first build the RF, then the CF and thereafter join them together. But this joining is quite a challenge because there are so many stringers, brackets and skins that all need to line up. Instead I’m going to continue section by section; so first the landing gear assembly and thereafter the main spar assembly and firewall.
I first riveted the forward luggage floor stringers in place:
Next I riveted the 6 brackets that connect the rf with the rear spar assembly:
There were 2 issues with the stringers that connect the rf with the cf. The flutes of the right and left piece were not at the same location:
With seaming and fluting pliers this was an easy fix:
I gave the end of the stringer a small bend so it doesn’t conflict with the first flute:
Finally the 2 holes needed to be enlarged to 4 mm because the main landing gear assembly has 4 mm holes at that location:
