Nice. Like how TPU hinge is integrated Appears that elevon just slides on, a nice design detail.
That was a serious tumble weed demonstration, something that is typically hard on a flying wing.

Thanks❤

What you reckon will happen if you print it with the hardest tpu you can find like 60-70D hardness and try to use as little of it as possible? I know material hardness doesn't show airfoil stiffness until you print it but still I am curious of the potential weight reduction if any.

woww... the first impact is very hard.... great idea in use TPU

Thank you !

This is the first time I have ever seen a 100 percent TPU sailplane! Incredible! Flies fast for 12mph winds, so it must be pretty heavy. Regardless, still beautiful and innovative! Looking forward to a build video and more details. Keep it up!

Thanks for watching. Design & construction video is available here - ruclips.net/video/eoSnLrfQoRs/видео.html

Great looking wing. What's the wing loading and wing span?

[@geode_rc]

Vital - Standard Valkyrie
Span - 90 (cm)
Area - 19.3 (dm2)
Mass - 780 (g)
Loading - 40.4 (g/dm2)

Looks like it flies like a brick. :) with enough wind, you can slope soar pretty much anything.

[@geode_rc]

Yeh, as low as 12 mph wing is good enough 😀

How are you mounting your FPV system?

[@geode_rc]

Thanks for watching. At this moment, this is not ready for FPV. A redesign of the front/rear end is required for FPV & motor.

Nice. You play with varioshore yet? I was thinking of CF reinforced low density vase mode TPU but not sure if I should bother. Eventually ..

[@geode_rc]

Not yet. I use 98A Shore hardness TPU with CF spar. I would try harder TPU if they’re available.
