Small update. Still busy with the Fokker on a daily basis, but currently puzzling on some minor issues in the prototype together with Ramses. The design is perfect, but some wooden parts seem to be slightly over- or undersized, both in thickness as in circumference due to inch-conversion and / or the laser cutting. When I solved those, I hope the rest of the wood arrives and I can make some more progress.
For now, I’m assembling some parts and sanding all the balsa parts. The toothed connection for divided parts works wonderfully and is easy to glue (I used white Aliphatic glue for this):
