Well, to tell the truth, I had a short break to finish an electric sailplane which I wanted to get ready for some winter-, and, next year, some holiday flying. And this is how it looks like when there is no space and you build one plane on top of the other ;-))

 
Back from the off-topic:

I cleared the debris and continued on the second wing structure and completed it so far that I started sheeting the upper side today.

 

I am working step by step with single sheets as they come from the hobby shop. This approach might seem a bit strange as normally, one would expect  larger sheets which have been assembled in advance? No way to proceed that way here and I do not fear any deficiencies concerning the wing strength. In view of the fact that the tensile strength of balsa is lower than the pine spars, the positive and negative g-load bending forces have to be picked up by the spar assembly anyway while the torsional forces are the task of the "finite elements" which are constituted by the fully closed rib/sheeting "tubes".
Thus, the work is proceeding fairly fast and I hope to finish both wings within the next days.

The sheeting is 3/32" (2.5 mm) and I strongly recommend to wet the outer side in order to relieve the tension from the many pins one has to use in order to secure the white glue joint. I am using a slow drying type of glue to leave me enough time to do the work.

 
  So far for today, back to the next sheet!

Looking good Herbert! Anything to report relating to pats and plans fit?
