Taking the plunge—literally! We’ve started our Open Water Diver certification with @diveindia, the largest and one of the most reputed dive centers in the Andaman & Nicobar Islands. After consulting our expert diver friends, we knew this was the right choice. Thanks to @divessi.india, we could complete our online learning while sailing, making the transition to real-time diving smooth and exciting! Stay tuned as we explore the underwater world, one dive at a time. Full video is out now!

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.
