I think this is more logically than 0:33 - 0:38


Professor Gupta - according to my design.

Dragonfly21-11 with Wing flapping amplitude change system　Test　Flight 2

Dragonfly21-11 with Wing flapping amplitude change system　Test　Flight 2 (6 min 50 sec)

A test flight 2. Flight control by changing of Flapping amplitude is very effective.
It does very interesting movement. It may be easily to do looping.
I am not yet good at maneuvering of this ornithopter.

Dragonfly21-11 with Wing flapping amplitude change system: An effect to a roll axis

Dragonfly21-11 with Wing flapping amplitude change system: An effect to a roll axis (3 min 15 sec)

Wing flapping amplitude change system ---- No Effect
A change of an attack angle of front wings ---- Rolling Effect

Butterfly20-2 with Wing flapping amplitude change system : Flapping Test

Butterfly20-2 with Wing flapping amplitude change system : Flapping Test (1 min 33 sec)

This is a new flight control system. Wing flapping amplitude change system.
Flight is controlled by changing the amplitude of flapping wings.
Flight control by changing of Flapping amplitude is very effective.

Good learnings
thanks for sharing
looking forward to your maiden flight of the flapping butterfly
best regards
Sam

great work D Kazu kind regards Brian

Butterfly 20-2 with Wing flapping amplitude change system : Servo motion

Demo Flight in Model airplane interchange society ( Department of Aerospace engineering of Teikyo university)

Demo Flight in Model airplane interchange society ( Aerospace engineering of Teikyo uni.) (13 min 39 sec)

Acrobatic flights,smooth glidings and nice hand-caytchings of the birds are impressed again
I'm convinced he staff of the Teikyo U were impressed too
the audience loved all the birds in the demo,but Falpter and Falcohobby gained biggest hands
great vid,thanks for sharing
best regards

Dragonfly21-11 with Wing flapping amplitude change system: Test Flight 3

Dragonfly21-11 with Wing flapping amplitude change system: Test Flight 3 (2 min 8 sec)

A test flight 3. Flight control by changing of Flapping amplitude is very effective.
It does very interesting movement.
I understood that either operation became Pitch Down.


Butterfly 20-2 with Wing flapping amplitude change system : Test Flight 1

Butterfly 20-2 with Wing flapping amplitude change system : Test Flight 1 (2 min 47 sec)

This is a new flight control system. Wing flapping amplitude change system.
Flight is controlled by changing the amplitude of flapping wings.
Flight control by changing of Flapping amplitude is very effective in Dragonfly 21-11.
But, as for Butterfly 20-2, it is not effective.
The amplitude of flapping wings is changing, but, Butterfly 20-2 can not turn.
I have to think about other methods.

GosHawk 26iV Light Ornitoper with 2mm EPP wing: First test Flight

GosHawk 26iV : Light Ornitoper with 2mm EPP wing (3 min 41 sec)

Width 94cm Length 44cm Weight 55g (180mA 2cell Lipo)
This ornithpter is in making.
A goal: Production of a light ornithopter less than 50g
It follows TB30--- http://trhk.exblog.jp/i16/
Power is insufficient.

Dragonfly21-11 with Wing flapping amplitude change system: Test Flight 5

Dragonfly21-11 with Wing flapping amplitude change system: Test Flight 5 (2 min 46 sec)

Flight is improved. I get possible to fly it slightly well.

Awesome
very much enjoyed the vid.
thanks for sharing
