Since childhood, I had adoration toward flying in the sky. I like birds
and do not get tired of looking at a flying figure of a black kite. In
elementary school days, I was deep in a paper airplane. At the time of
junior high student, I flew a radio control airplane for the first time,
but the airplane crashed by the first flight. It was continuation of a
crash afterwards.
I became a doctor, and I got possible to spend money freely and came to
let at last you fly in a model helicopter somehow. However, it required
the part purchase, adjustment and money and time abundantly and gave up
the helicopter. I have been tired when I fly a too fast model airplane.
So I arrived at gliders. In particular hand lunch gliders are small and
are hard to be broken even if I fall, and repair can immediately even if
broken. A small hand lunch glider I forecast wind, and to fly is pleasant.
I can fly it in a park nearby.
In winter, 2005, there was broadcast of Indoor Plane of Mr. Koichi Tanaka by the NHK eagerness times. I watched this, and I enlarged a dream to
the ultra small radio control airplane which could fly indoors. I run about
for study, the material gathering immediately and make No.1 airplane of
3g in weight (Indoor 1).
I made No.2 airplane (Indoor 2), and I was captivated by a ornithopter of Mr. Takahashi.
I made an ornithopter (butterfly 1).
While I made it, it flashed when an ultra small pteranodon of radio control (Pterosauria) might be made by this method, and I investigated documents of a pteranodon.
I found documents about detailed flight of a pteranodon and started a reading, production.
I did various trials in Pteranodon 1, but it does not fly well, and I learn
it from failure and make Pteranodon2. And I make smaller Pteranodon3.
Now I am making Pteranodon5 which had a near flight system to a more real
pteranodon afterwards. I have a dream to fly Pterosauria.

I want to show it to allergic children (my pacients). However, I do not
get that time in medical examination and treatment. Thus I put the appearance
that pteranodons fly in HP.
When you click an image, a detailed page opens.
There is a video of a flight (VTR).

I have described the progress of the development of
the pterosaur-type ornithopter from 2007
to the present (30/June/2023).

A publication article on Flapping Wings
An article about my Pterosauria type ornithopter was carried by the news letter which American The Ornithopter Zone published.
I wrote an article by a request from Nathan Chronister which was the sponsorship.
