Exploring the beautiful Folkestone Warren for sea glass, with stunning views of the white cliffs. Be warned, this hike is tougher than it looks! This was filmed in 2022. #FolkestoneWarren #SeaGlass #CoastalHike #WhiteCliffs #HikingAdventures

Test of the hover controller, in particular in yaw direction (multicopter frame, i.e. roll direction in airplane frame). The yaw is stabilized using the flaperons which are in the propeller wash. The flaperon deflections are visible when Chris pokes the kite with the broom. The controller quickly reacts and stabilizes smoothly the yaw angle back to zero. Note that differential propeller directions as used for small multicopter-drones do not offer nearly enough yaw moment for control authority of the kite's inertia or expected wind loads. In addition, such a control scheme greatly reduces the thrust for yaw stabilization. This is why this is not feasible for our system.

Did you know that octopus can change the color of its entire body in just three-tenth of a second? They camouflage themselves by changing color and pattern to match with natural features or even other organisms nearby. They truly are the smartest invertebrates on earth! Come and explore the underwater world on our catamaran "Primetime" with us, next stop SULU SEA PROJECT 2020 with WWF-Philippines in Tubbataha and Cagayancillo.
