All your new birds have hybrid wings yes???? not just plain membrane , the front is solid yes ????

regards Brian

thank you my dear friend Brian.
membrane wings only for dragonfly,others are all hybrid with solid front.

Great work Sam

So why not try using the dragonfly flapping mechanism to flap and actively twist single wing ...it will take some trial and error to fine tune the out of phase motion of the double spars but you will get there ..

Good luck ... I know you can do it ..

Khaled

thank you indeed Khaled.
it's always nice to hear and learn from you.
my tailless dragonfly had a hard crash 2 days ago and it takes time to fix.
I'll study on the double spars concept per your advice.
you are awesome and a nice gentleman to the ornis' world.
