Wow. I sense a string might be involved but impressive nonetheless.

I think the circle was a bit irregular for a string to be involved, but
I'd guess it certainly didn't do that with the rather rough trim setup
shown in the video: plenty of up-trim, but what he did to get the tight
turn wasn't obvious. I'd think a few test gliders were in order before
trying it over the stove - either that or a set of oven gloves would be
needed.

He has flaps right up / left down so the turn is no surprise, and he
says that was the 87th take because most times it doesn't centre
properly.

Um... wouldn't those flap settings cause a RIGHT turn? At the very least, a right bank... or have the laws of aerodynamics changed since I did my licence exam?

Then again, perhaps the plane is actually doing right turns, and it's only my fading vision or fatigued brain that thinks it turning left?

Maybe he integrated a really good thermal assistant... :-P

I saw that the elevons were bent to 90 degrees and did at one point think
I saw one down. However I thought that the last shot of its rear end
showed them both up, so thanks for correction.

I'm not surprised he took several shots, though 87 seems like a lot.

On a related topic, back in the 80s (IIRC), a few of the American indoor
fliers discovered they could win Indoor Hand Launched Glider contests
with very light microfilm covered models that they launched over a patch
of sunlight on the floor of the venue. I heard about this but never saw
plans or photos of the models: does anybody know if there are any films
or videos of these things flying? They'd fly a lot like that paper glider
though much slower.

No, but search for walkalong gliders on Youtube. Varietal constructions, paper and foam, tumbling and stable.

I built one of these models. The covering was made by floating a film of
dope on water and very gently lifting it off and covering a very light
balsa frame. They did work as you suggest.

PT Barnum was right.
