From the paper by Hiroto Tanaka and Isao Shimoyama entitled "Forward flight of swallowtail butterfly with simple flapping motion," Bioinspiration & Biomimetics Volume 5, Number 2 Paper 026003, 2010. dx.doi.org Abstract: Unlike other flying insects, the wing motion of swallowtail butterflies is basically limited to flapping because their fore wings partly overlap their hind wings, structurally restricting the feathering needed for active control of aerodynamic force. Hence, it can be hypothesized that the flight of swallowtail butterflies is realized with simple flapping, requiring little feedback control of the feathering angle. To verify this hypothesis, we fabricated an artificial butterfly mimicking the wing motion and wing shape of a swallowtail butterfly and analyzed its flights using images taken with a high-speed video camera. The results demonstrated that stable forward flight could be realized without active feathering or feedback control of the wing motion. During the flights, the artificial butterfly's body moved up and down passively in synchronization with the flapping, and the artificial butterfly followed an undulating flight trajectory like an actual swallowtail butterfly. Without feedback control of the wing motion, the body movement is directly affected by change of aerodynamic force due to the wing deformation; the degree of deformation was determined by the wing venation. Unlike a veinless wing, a mimic wing with veins generated a much higher lift ...

TRICKS - KAMAKAZE hand launch and easy catching An "Ornithopter" differs from all man-made flying devices in that it flaps its wings to propel itself through the air. This is a form of flight that most resembles the natural abilities of birds. The i-Fly VAMP ™ is styled to resemble a fantasy-inspired bat. At 12" in width and 10" in length it is the world's smallest radio-controlled ornithopter in the form of a bat. The flapping wings mimic the behavior of a bird or an insect, giving the eerie illusion that the toy is alive when it is in flight. In addition, the ability to control the i-Fly VAMP ™ through the use of a digital proportional radio controller gives the illusion that the VAMP flies along an intelligent path. The glowing eyes of the i-Fly VAMP ™ add to its mystique as a supernatural nocturnal creature.

Video of my Slow Parrot and a real bird flying together. I added the Bald Eagle profile picture to make the model look even better. Nearly every flight has attracted the attention of real birds. This video was shot during nesting season and resulted in the defensive actions of this Mocking Bird. Late afternoon flights always draw in the Buzzards who seem to think the Slow Parrot has found a good thermal. I also fly it with a 3s battery for amazing climb performance. This model has been lost twice due to winds around 8-10 mph. Both times recovered within 1/8 mile in the woods behind the local flying field.
