I was out flying just before dark yesterday and after recalibrating my compass and letting the satelites lock in I took of and started flying. I probably hadn't been in the air for 2-3 minutes when the copter started loosing altitude and came down gently just missing my neighbors storage building. Fortunately it landed in a patch of dead weeds and no damage was done. I cycled the power on the controller and copter and let everything reset. I flew for another 20 minutes and never saw any signs of trouble. Any ideas what might have happened here?
