For the construction of the wings, the stab and rudder, I used Profili software.
After generated the profiles in Profili and importing them in good dimension in autocad, I separated the upper profile from the bottom while keeping the same basis reference.
To cut at the correct speed on both sides with the hot wire, I draw vertical lines, I will avoid doing so in the future because it is easier to draw directly them on the Formica and the problem with the vertical lines is that I should not go till the end because the risk of hanging with the hot wire is high. So I restarted everything.
You need to make a perfect surface so the wire does not catch anything, a light sanding with very fine paper achieves the goodsurface.
The value of computing is that I could directly integrate negative twisting wing tip easily.
Then the CNC has cut into the formica templates of the wings, stab and rudder.
Here are some examples:
Stab + rudder 1st version
Second version of the rudder thickened.
