Dragonfly Dogfights
Like fighter pilots of old, male dragonflies engage in aerial combat where each tries to outmaneuver the other to keep a sight on their rival’s tail. A recent study observed this combat in the field and uncovered some surprising similarities to dogfighting. Like pilots, dragonflies used spiraling turns and other high-g moves to gain an advantageous position behind the other. In human combat, that position favors the forward-facing weapons of the pilot in back; for dragonflies, it keeps their rival in the part of their vision that best detects movement.
Interestingly, the team found that–even in the midst of combat–dragonflies spent at least a third of their time gliding. It’s unclear whether they glide to conserve energy or because it’s easier to track a rival when gliding.
The authors dig into the control rules needed for dragonflies to execute these chases and found that even relatively simple control schemes–constrained by the dragonfly’s physical limits–result in complex flight contests. (Image and research credit: S. Fabian et al.; via Ars Technica)

Controlling Hovering
Hummingbirds and many insects hover when feeding, escaping predators, and mating. While scientists have decoded the mechanics of a hummingbird’s figure-8-like hovering wingstroke, it’s been harder to understand how the creatures control their hovering. Most of our attempts to control hovering require more computational power than hummingbirds and insects are thought to have. But this study describes a new control scheme: one that allows stable, real-time hovering with little computational cost. (Image credit: J. Wainscoat; research credit: A. Elgohary and S.

🚀✨ #Flightcontrol promises to make #AWS a dream and ends up as a cloudy nightmare of #buzzwords and emoji-like redundancy. 🔄💸 "Outgrowing" other PaaS? More like "outgrunting" through yet another sales pitch for 24/7 "support" that is as comforting as a Windows XP error message. 😂🔧

Flying Without a Rudder
Aircraft typically use a vertical tail to keep the craft from rolling or yawing. Birds, on the other hand, maneuver their wings and tail feathers to counter unwanted motions. Researchers found that the list of necessary adjustments is quite small: just 4 for the tail and 2 for the wings. Implementing those 6 controllable degrees of freedom on their bird-inspired PigeonBot II allowed the biorobot to fly steadily, even in turbulent conditions, without a rudder. Adapting such flight control to the less flexible surfaces of a typical aircraft will take time and creativity, but the savings in mass and drag could be worth it. (Image credit: E.

Skydiving Salamanders
The wandering salamander can spend its entire 20-year lifespan in the canopy of a coast redwood. When predators come calling, they have a special skill that helps them get away: skydiving. These little amphibians have no webbed appendages and no wings, but they’re some of the most skillful skydivers out there. By carefully repositioning its tail and feet, a wandering salamander controls its pitch, yaw, and roll. It’s not only able to orient itself as it falls; it can actually steer itself to a safe landing! Other salamander species, as seen in the video above, do not share this skill. Check out the full Deep Look video to see these incredible gliders in action. (Video and image credit: Deep Look; see also C. Brown)

I need some ideas for finding a rudder pedal to use in dcs. It should cost around 100€ while less is better.
Right now I do use the z axis as a rudder control on my T.16000M, but this thing got some real jitter and is far from precise.
It needs to be shipped to Europe.
Any ideas or recommendations?
