Ok so I reduced the tip diameter a few mm. See the diff:
Agilus-5
The extra segment in the wingtip should also make the sewing easier. I don't expect any performance improvements.
I will join the sail panels in the CAD program (takes me a few minutes) and put the "join_panel" function on my todo list. Winter is coming
The Ventus in 4.2 has still a lot of pull and is too close to the 5 so the next smaller size should be around 3.8.
Do you want to build both sizes together to save some time?
I will finish the DXF and PDF of the 5.2 on the weekend.
Here is the first draft of the Agilus-4:
