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.

Chinese sailor Jingkun Xu's wore his heart on his sleeve as he raced around the world. So did many of the other sailors and while everyone's story was fascinating, the fact that Jingkun has just one arm speaks no English and ran his entire campaign with barely any shore crew made his story all the more fascinating. But his journey was more than that - when he talked to the camera he did so to mark a moment in his journey, for good or for bad and you just couldn't help but get drawn into his world. This week we take a summary look at his incredible story and trip around the world in our Week 15 review - here's a teaser. @VendeeGlobeENG @xujingkun99hines

Questo video riguarda Gassa d'amante e nodo bandiera. Sono due nodi marinareschi fondamentali. La Gassa in questo video è eseguita in uno modo molto semplice ed efficace che tutti i bravi marinai dovrebbero imparare! :-)
