小型アジサシ型羽ばたき機 Sterna139 66g： 5th Flight Test and Gliding in strong southwest Wind

[@fsangre]

Beautyful ! And impressive good work, as usual !

[@BZH07614]

Thank you.

The wing seems more resonant now, and wing beats result more pronounced

[@poobertop]

Do you think it would be beneficial to have the outer half of the wing rigid and non-flexible?

[@BZH07614]

Yes. I agree.
After this test flight, I added a second 0.6mm carbon rod to the 0.6mm carbon rod in the WingTip section.
