Hi Anthony,
I used the a400m updated file you posted for Karsten is there a later version in the new Prop Designer ?
Re the scaling factor I used the distance from Span to B curve points for my calculations and if I understand you use Span to A (leading edge) curve points I will check what difference that might make.
Regards the network option see attached photo and just to be sure I only use the A & B curves plus the airfiol profiles the span curve is not used.
