## Improvements in the flight controller behavior

With this update we have significantly improved safety aspects of the flight behavior in particular emergency landing behaviors under motor failure. It is also expected that flight behaviors are more reliable in particular kite heading control under significant disturbances such as high gusts of wind.

There are other under the hood improvements which should further improve reliability under sensor signals deterioration such as those of GPS.
