Hello anyone have this symptoms? After a nice flight I return to land and the drone does this little circling right at ground level before landing. I've calibrated GPS before but not at every flight, and this happened more than twice and crashed on the ground plus broken propeller's. And twice I've caught it above head level, then turned off by pressing red button because of this circling effect. Any input? Thanks! Note: had 20 satellites before, during and after flight.
