Hello!
Vinalssergio155: thank you.
Isaac: good idea! I will make two versions to choose from: with petals and conical sections. Thank you for the idea.
deltapike: I hope that the render with the view from above will explain everything.
chicharrero, Richschindler, Lex: thank you very much. I try to make my projects as good as possible. I hope that this time it will also be like this.
BTW: the model is tested by a colleague
Andrzej Ciepłuch.
Next photos: frames of the rear part of the fuselage.
Best regards.
