Over the weekend we finished the cores for the third pair of wings. They also look very good. Excellent stiffness, and the weight difference between the two wings on the second pair is only 8 grammes and the two wings on the third pair only 5 grammes (on a total weight per wing of around 830 grammes).

Georg covered the first pair of wings in glass and yesterday cut off the outer wings and added the dihedral (V-shape) to the two outer wing segments. The system for the exchangeable outer wings that we built into the wing cores works great, both outer wings (4.28/15m and 5.14/18m) are a perfect fit, and the wings look just like the original. Hopefully we should be able to do a first fit of the full model in the next few days.
