Neat stuff. Here is another variety:

I do not offer this as a way to use a vertical shaft engine on and aircraft, just an example of how it's been done in hovercraft and airboats. They use a v belt and two extra pulleys for hte 90 degree change. The belt is long enough it can twist easily. I'm not sure how one would tighten this...

I still think this would be cool for small venues.

I'm not an expert on the Timbren. The info calls out hollow rubber bladders for the main support. Also there is an opposing rubber bladder on the front side that acts as a damper. No air bags. I've never seen it or how it works but it is interesting.

In a similar vein, I would present also the ZDZ engines (4 cyl 420cc and 500 cc) available with electric start and 1:2.7 reduction. https://www.zdz.eu/inpage/zdz-500b4-jsr/ 37 pounds (17 kg) and 50hp...$6k range

I agree, that the independent caps might be able to move. Now, the view (#3) showing the C channel top and bottom and the corrugated panel in between might be good, approximating a box spar.

I found this video of the Bally Bomber leaving Oshkosh 2021. I cannot help but love the look of the pilot hanging out the cockpit while taxiing.

Good tough machines. Interestingly, derived from Volmer Jensens' original VJ-23 design, then beefed it up as the design grew. Here are some pics of the prototype. Note that it is still a cantilever wing design at this point, and I assume it could be dissassembled just like the VJ-23 could. He...

...and Fat Albert still had rocket-assisted takeoff...that was cool.

I liked that book too, Pops.

Rather than a heat shrink covering what about a formed (molded?) piece of trim? A stiff but somewhat flexible rubber or plastic. The front side open with a channel made to snap on over the able, but not entirely cover it. You could see the cable to inspect for fraying and if deeper inspection...

Stits had some neat options. I wish his plans were more available rather than $300 sets from a museum. These were proper quick release and manual fold affairs. I would love a copy of these plans!

Looks like an Eaa Bipe

For those that don't want to find it on the site: UWS-4 design As far as Facebook goes, it is what you make of it. I've edited and blocked all the junk news feeds and have it tuned to show all the hobby groups I like (boats, motorcycles, airplanes, model building, gardening, etc) and...

Just a picture added to a post.
