and further ...
Now to the tower. Spant T18 is installed in the turret using auxiliary lines.
I reinforce the frame with 2mm cardboard.
Cut out the 12 "windows" and glue them to 0.4mm colored cardboard...
In the area behind the "windows" I glue cardboard with 1.5mm Finn and cut out the openings again.
Sincerely
Kurt
