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.

There is a video of a flight (VTR).
