The 1st method, split aileron
Thank you for the information.
I had not seen this video.
Development of my bird type airplane started in 2002.
At first, although it was the method of moving wind end wings, this was able to turn only at a few.
Then, I investigated the frame of the bird and considered how to move by a frame.
Then, I thought of how a bird is stale about the back of wings.
By this method, rapid revolution became possible.
This method is split aileron.
However, by the method of a split aileron, revolution of the sea gull with the thin point of wings is well impossible.
Now, the method of circling by the method of changing a camber was added.
I think that a camber aileron system becomes the method of using by a flapping-of-wings mechanism.
