I am glad that you like your blades, but I think that I should warn the rest of you that if you want to do 3d/inverted flight, these are not the blades for you. Like a real helicopter, the flexibility of the blades makes it impossible to do loops or fly inverted. If you did so, the blades would flex downwards causing a boom strike (or killing you if it was a real helicopter). I am sure they would be fine for hovering and FF though.
