Apart from my artistic painting I also like technical stuff. Its a bit like curse if you have multiple interests to enjoy. I took little break from painting now. While sitting in my backyard watching birds flying around I was curious how do they produce lift and thrust by flapping wings. I started watching different articles and videos on the internet about that. Accidentally    I came across  some thing I have never heard of called an ornithopters. I was hocked up.
It looked like very nice to do some fine technical things when have free time (semi retired now). And few months ago I have built my first rubber band powered ornithopter by free plans from website The ornithopter zone. Was not so simple to by different materials and parts, learn about glues. etc. But I have done few of them. They flew nicely but with rubber band power and without any controls flight where very short and unpredictable.

This video is recorded with iPhone camera  slow motion 240 Frames per second.

Actual flight lasted only about 30 sec.
