Crash Incident:
At approximately. 1930 hrs. I flew one flight on newly charged batteries. Flight was approximately 8-10 minutes. I landed and took off. I flew approximately 25 yards at approximately 15-18’ in height over a metal roof canopy. Brought the aircraft to approximately. 20 ft and it then descended without any control. It went to a hover approximately. 3-4 ft above the roof. Rear light was flashing yellow rapidly. I had no control response. The control sticks had no action, return to home did not work, pause had no effect.
I moved myself and controller withing approximately 15 yards with no change. I then purposely change the angle of the patch antenna to various angled position with still no response. I raised the controller above my head. I moved myself / controller both right and left approximately 15’. I tried “return to home” with no response. I tried pause button several times with no response. The rear continued to flash yellow rapidly.
After approximately 10 minutes the aircraft dropped to the roof and slid down the roof to the edge. As it slid off the roof, two blades were broken while hitting a rot-iron fence below the roof line. It came to rest on the ground (cement).
I suspect it only descended after the battery went dead. The CrystalSky maintained a full screen picture but not sure if it was just a frozen screen. It never did a return to home when the batteries were low. I had NO control over the aircraft.
Any comments welcome.
