New props came today. http://www.ebay.com/itm/121090066480?ss ... 1439.l2649 9 days from purchase to delivery, pretty fast from HK! These came already balanced! I was surprised when I saw that they had some light sanding on the undersides, and sure enough, almost perfect balance. (I did add a tiny bit of tape on two of the four though) I'll see how they stack up with a test flight in a while.
