Brett,

 Thanks for that info. Believe it or not, that gives me a pretty good idea of the rest of his structure. Based on some videos, I'm estimating that his stabs are no more than 120 mg because they appear quite floppy. It also would appear that the inner pair of wing ribs are only for keeping the basic airfoil shape. His motorsticks must be incredibly strong--there's a lot of weight budget available for them!

P.S. thanks everyone else as well. How can I contact Larry?
