These pictures are very nice and they support my general thoughts as to why the Stelzer wing has not (excuse the pun) taken off. If you look at the mechanism as a free body diagram you will see that the pivot is too close to the wing in comparison to the size of the wing and the placement of the "sprung" support behind the pilot. Too much force of the gust loads will go directly into the frame and not the spring. In order to work properly the layout must be like the patent sketch which puts a majority of the load into the spring while the pivot only, well, pivots! Otherwise this is a great attempt at using the concept. Another way to get the pivot point out front would be to use a non-symmetric scissor mechanism but this would require some way to lock the wing from rolling relative to the fuselage.
