Yeah, I think it's more of an Oshkosh show mock up that might just barely fly. Mock ups need all the features. That's the only explanation I can imagine.

Yes, most can be ordered in either version. There is various reasons for choosing one or the other.

Lawnmower engines are vertical crankshaft. They are converted to horizontal.

I built and tested a wing D-cell almost like this. The caps were stacked (laminated) .032" 2024-t3 formed angles. The laminated angles didn't work as expected and started to buckle in compression between the rivets. I added an additional angle of .125" extrusion. The lesson was that laminations...

Direct drive. Lots of folks are converting the vertical shaft Briggs and Stratton 810 to horizontal. Search for SD-1 discussion here or elsewhere.

Sugar and white flour are considered simple carbohydrates. Potatoes are complex carbohydrate. Brown rice, whole grain wheat and whole grain corn are also complex carbohydrates.

You might find a used 25hp lawnmower. Remove the engine and convert it to horizontal shaft.

A rolled high strength alloy tube might have superior properties compared with extruded. Or a custom extrusion with thicker caps might be ideal. The kits were probably round "drawn", which is not the same as "extruded".

I think the 1976 model has the drooped cuff on the entire wing.

Wheat is poison to me also (gluten). But unlike Americans, most of the worlds people stay slim and almost no diabetes with starch centered diet for energy and less than 10% meat and dairy. (book source: The China Study, T. Colin Campbell PHD Nutrition Biochemist) The MIT Daedalus human powered...

Or weld a tab to the nut.

Might need .020" at root. I recall that Lazair upgraded to .020" and the strutted Lazair wing is much lower bending moment.

Get a long nut and bolt on the outside end of the long nut. No clearance issue. About the same as a thick spacer, I suppose.
