This might be of interest to those building an S1...
I have converted all of the components in the fuselage to cad and have had all components cut by water jet- better than laser as the edges of the components are not hardened. I am also in the process of getting all the tubes cut by laser from a 3d cad drawing, so no cutting and filing by hand.
If anyone is interested in a complete or partial parts kit, please let me know.
