Kinkade Yard Hawk
This is almost too nice of a work-of-art to actually fly. It is really a thing of mechanical beauty. If like me you had the small Tim Bird as a kid (rubber band powered ornithopter), you have probably dreamed of flying a genuine R/C orni. Well here it is, and it does not disappoint! If you're not familiar with orni's, they use some interesting gearing to transfer rotational motor output into linear wing flapping. The flapping wings are indeed the mode of propulsion, and the steering is via tail tilting similar to a real bird. There are several sizes of Kinkade orni's, this is the smallest at a 26" wingspan. It is also the quickest and most maneuverable. It is definitely not for beginners, due to the unusual appearance in the air orientation is a real challenge. And landings can be tricky as well, one wrong move and you will have broken parts or stripped servos to deal with. But there's nothing like it to stop people in their tracks at fly-ins!
These are available at http://www.ornithopter.org/ and are largely pre-built. Final assembly takes a single evening.
Equipped as follows:
Brushed motor (380 size I think)
3s1p 730 Thunder Power li-polys
Hitec HS-55 servos (x2)
Wingspan is 26", length 20"; weight without battery pack is 8.5 ounces, 10.2 ounces with battery pack
I recently bought a second Kinkade ornithopter, this one is called the Park Hawk. It is very similar to the Yard Hawk, but is slightly larger. It flies slower and will glide a bit as well. It is not built yet, below is how it comes out of the box. It has a 42" wingspan compared to the 26" wingspan of its baby sister. I really dig the neon yellow ripstop!! This picture was taken in the shade, maybe you can imagine what it looks like in the sun!
