I just got my order of 3 racing spur gears and they are all true. The ones I got are not flawed in any way. Maybe there was a bad first batch that was shipped out. The new 2 speed setup is pretty interesting as well. the first gear 1 way bearing actually rides on a steel collar so that they can use a larger bearing as well as a titanium shaft. I will take pics and let everyone know how it works when I get it mounted up. I was pretty amazed how fast I got my order from RC Mushroom. It was sent out form Hong Kong on Tuesday, and it arrived today. That is fast! Yee haw.
