test flight of my TAROT IRONMAN FY650

Well, obviously this one didn't go as planned. Pilot error: I lost orientation for a second and pulled off the throttle, and it lost altitude, okay, ALL altitude. I simply got confused and didn't give it enough throttle to keep it from hitting the ground. Disappointing. But the arm shouldn't have broken since it was not a very hard landing. I think constantly snapping the arms in and out of extended position may have weakened them. This inspire me to move all the gear over to the Lumenier QAV540 frame. I will have to make my own gimbal mounting plate for the camera but i like that the lumeniere frame has aluminum arms (which bend, not break) and short landing gear that stay out of the way of the camera, not needing to be retracted. Back to the work-bench.
