nice bird! you lowered the flapping frequency for this one. Usually what is the difference between the frequency with wings and without wings? is it divided by 2 or less?

Thank you,
Good work!
Thank you.
Articulated wing is low flapping by increased thrust?.
And wings of Goshawk25iV has Aerofoil, so, lift is big?
Then, it necessary a few falpping.

[QUOTE=Kazu-kaku;23656559]GosHawk25iV with articulated wing


It flies great Doctor. It bites and swallows a big portions of distance with every beat of its wings and this along with the articulation and relatively slow rate of flapping make it look as a real bird. I suppose it isn't only about beautiful wing motion but it's more efficient as well. I am sure that this bird can take longer distance on the same battery charge than conventional non articulated wings or passively articulated one.
Will be very kind of you if next time Syu record it in slow motion.
Thanks for the detailed technical data report as well.
Bravo very good job!

Thanks to Kjell as well for inventing and demonstrating this simple but effective (Wing tip accelerator)system!

チゴハヤブサ FalcoHobby 22iV Acrobatic Flight: Looping and On the Tree (4 min 1 sec)



Actobatic Flight. Looping and On the Tree.
Good acrobatic flight. I added 1mm Carbon rod on wings for to increase thrust. Then, Loop is OK.
I have spurted too much carelessly, FalcoHobby22iV has been caught on a top of a tree.

Colored Body.
I change 0.8mm pianoline which is using in order to bend wings to 1mmPianoline with tied 1.4mm carbon rod beside pianoline.
The wings came to turn well and thrusts increased.
Good Flight and Gliding.
