My friend Bruno made this video with his scratchbuilt tricopter. On second launch the battery plug unplugged itself because of the high g- force, so the glider crashed. We repaired it on the field, 3rd launch was perfect, on fourth launch the booster bottle separated from the glider. Now it is repaired at home.
