after the rapid delivery were the rotor guards, assembled and immediately the punk quality was evident: begefügte screw does not fit exactly with the prev thread and are very very soft steel.. The rotor protectors are designed so that the propeller in flight grind it, after the first flight already considerable abrasions were visible, so I could no longer set to return. The Props are extremely soft and the Phantom so flies considerably worse than the original props. I would never buy these things again.
