I was filming with a regular client of mine this week. We had just finished doing a shot when the first level battery warning was shown (25%). I began to bring the Inspire back to land about 10 feet in front of me, or about 30 feet from my take off position. I had the Inspire right in front of me and I brough the landing gear down and brought the throttle down to land. When the aircraft was about 1.5 feet from the ground, it hit the second low voltage warning (15%) and attempted to return to home. The aircraft rose rapidly upwards, I looked at my iPad screen and i had no option to cancel the RTH, nor would it accept my stick inputs. The aircraft continued to rise until it clipped a tree brach with a prop and tumbled about 30 feet to the ground. The Inspure broke a leg, jammed and bent the camera and bent the frame and centre worm gear. It was very frustrating because i was 1.5 feet high with the landing gear down and throttle down, ready to land when it shot up and hit the branch. Is this worth a repair or is it dead? Does anyone have any thoughts/ advice/ constructive criticism for me?
