Our Haas GR-712 CNC machine and her crew are hard at work milling a laminated sapele wood transom. The transom will be installed on the construction strong back and glued to the keelson before the hull planking is laminated in place. It is one of many structural components cut by the CNC for the new LM 65 ft cold molded sailboat project.

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.
