After you made the Corsair, I stated to try the same with an ASK21B.
I found a 3 Side View on the Homepage of Alexander Schleicher
and took that for my Lesson of making Plane in Freecad.
My Goal is to create a Hangglider for myself,
because I'm a Hangglider Pilot and I have Ideas for making
better Rigid Wing Hangglider than the Existing Ones.
I think it is more complicated to work with Faces that are bent in many Directions.
That's the Thing with the Design with normal Planes.
When I do an Airfoil Design, there is in Addition a Workflow that is not so
easy to follow in Freecad.
First you must simulate a few Shapes of Wing Designs in an Airflow Simulator such as XFLR, OpenVSP, or such.
That helps to find out, which Design has the best Flightcharakteristics.
In many Cases you end with having a .dat File and the Angles of the Wing in all Axes.
But for now, I found it difficult to work with it, in Freecad.
It is much more complicated as doing mechanical Engineering, for me.
