Thank you very much, Ondra!
All your words proof again what a great place this is here.
Meanwhile I painted the interior. I took the opportunity to replicate the typical Fokker metal with a gel pen which worked perfectly. I cannot remember where I read this idea here on this forum, but thanks for the hint, it's really a simple technique.

For the wooden parts I switched from oils to acrylics. Worked fine too and dried within hours.

Here's a test fit of the cockpit component. I am afraid it needs some sanding to fit between the fuselage halves...

As this is a pure fun build, I thought about using the kit's Oberursel U. I. But then I changed my mind and built up a spare Oberursel from Wingnut Wings.

Now on to the seatbelts...
best regards
