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.

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

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.

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.
