The Orvillecopter, half cat, half machine. Named after the famous aviator Orville Wright. He was killed by a car. After that he received his propellers posthumously. This is Orvillecopter's first test flight, Soon to be flying with the birds. Oh how he loved birds. He will receive more powerful engines and larger props for his birthday. So this hopping will soon change into steady flight. For the catlovers: it is a tanned hide, just like the shoes you're wearing.
For the RC lovers: it's a Lotus T580 (still)
