Multicopters have always been an intriguing aircraft to me. My first knowledge of such device was a RC micro-saucer device from a company called Keyence which I saw at Akihabara in Japan back in the early 1990's. Few years later I was excited to learn about a company called Area51 that manufacturers a larger quadcopter called Roswell Flyer, which was able to fly outdoor in gusty conditions. Then my collection started to grow, everytime a new multicopter comes out, it goes on my most wanted list. Yeah I guess you can call it a fetish.
Here are some of the copters that I took photos of over the years. I really wish I still have the Keyence saucer, as it represents probably the first commercially available multicopter. But that has long been MIA.
