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.

A few final days in Japan before an early flight south. This short video captures some familiar New Year sights: Mount Fuji from the train, the Sumida River and Tokyo Skytree, and the crowds taking part in the annual tradition of visiting a shrine. After five weeks away overseas with family, and finishing the manuscript of my latest book during a brief return to Tokyo, I’m heading back toward my boat, Wahine, in remote Uken Inlet on Amami Island. A small pause before the year gathers speed — and before the next chapter begins. #NewYearInJapan, #SlowTravel, #writerslife #PacificSolo, #JapanMoments, #ArtOfCommunity
