I got my plasti-blades from HeliDirect.com, along with the Super Skids. There is a weight penalty, and I'm down to about 5 mins flight time with the stock motor and battery, but its not costing me $17 / per flight when I trash the wooden blades on one of my "landings". Where I would have gone through over 10 sets of wooden blades by now, the plasti-blades barely have a nick in them. I am bending the main shaft more, but its easily straightened, and its also alot cheaper to replace than the blades.
