DXF-data ASK 18

The DXF data of Hermann Eichner refer to the ASK 18 designed by Arnold Hofman (VTH construction plan 3200707). They allow the production of the components on the home CNC milling machine or at a milling service.

The data includes all major components such as ribs, frames and the slipway. Compared to the original construction plan by Arnold Hofman, they have been modified and modernized: Among other things, with a more powerful airfoil (now: SD7034), with support feet and without a pre-sweep for easier assembly, with a comb spar and a modified wing stitching.
