Could we get serious for a moment... I've had two of these fans break apart at 1/4 throttle. The spinners both split on the first throttle up at 1/4 throttle. One Starmax fan was from Hobby Lobby, which by the way included an extra spinner and fan. I asked Hobby Lobby about the extra parts before I ran the fan and was told that the fans have been known to break up. Had the fan been run up at least once at the factory I'm fairly certain that it would have broken the same way it broke when I ran it. Also if the fan needs the delicate care that you speak of it would of been nice if these details would have been included in the form of a RED piece of paper included and taped to the fan. I guess it's just easier to call the plane a RTF and assume that the buyer is a mind reader.
