A few days ago I was searching for some wires for my charger I came across some Carbon Fiber blades for Coax helicopters here: http://hobbyfly.com/en/helicopters-48/helicopters-rtf-4ch-183/-2170.html?language=en
I think this will be a nice birthday present for myself. I am going to try these on my Lama smiley I am hoping the bird becomes better at flying straight as these blades should be stiffer and more durable.
