You might also want to consider the liability of some yoyo who just HAS to do a full-bore dive from 1,000 ft, and with max (3D) elevator pull-out, the wings fail. Of course the story YOU would get is "gee, there I was flying straight and level at half throttle, and the wings just folded..." Given that they did absolutely none of the building or even assembling, it would just HAVE to be manufacturing fault, right ??! Then they want a refund, or a totally new plane, etc...

OK, so maybe I am just a little sinical...but, something to think about when folks lay out that kind of money....
