Flapping Eileron

Wings are flapped and direction is changed.
Right wings are raised and it circles on the right.

Very interesting concept Mr. Kanai.
Did you test it in flight already?What are your impressions, is it working well or even better than your previous concepts?

Nice work.

Very interesting. With the angle of the hinge line I would expect the rising panel to have an increased angle of attack, so roll the model to the left. If it turns right, I guess it must be the increase in drag that is the dominant effect.... much like the drag brakes used to turn a paraglider.

Looking forward to seeing a video of it in flight.

I imagined that technique but I really didn't think I would see it. Birds do that all the time (but opposite). Excellent Mr.Kanai! Let know how the new way turns out.

The impression of a test flight

Although the hand throw was carried out about 15 times from the bank, the course has been changed safely slowly.When the right wing was raised, it inclined to the left at first, then direction was changed to the right.
Since it went to the bank alone today, I was not able to do video photography which is flying.
I think that there are some kinds of methods at which a bird turns.I think this method is set to one of them.

That makes sense to me. - At small deflections the outer panel would give increased lift but not much drag, and so a raised right wing would give left roll. At large deflections it would give lots of drag, so model would yaw and roll right.

Kanai, can you make it a raised wing and lower the wing the direction you want to turn?
