I've used CF, JCS Plasti-blades, wood symme's, wood flats. My money is on the plasti-blades full symmetrical. Why? CF is EXCELLENT but pricy. Wood anything blows apart if it hits anything, replacing blades can get expensive while learning just to hover. I'm on my second set of JCS full symmetricals and I beat the stuffings out of the first set (and they're still useable). Drawback to plasti-blades...Other stuff breaks because the blades dont. I've gone through 3 tail booms, 5 spindles, 3 main rotor shafts...get the point? All the other stuff you'll break with plasti-blades still won't cost as much as 1 set of wood blades. Trade off. Another bad thing about plasti-blades is they don't seem as smooth in operation as the woodies or CF (vibration), and I haven't found a way to balance them or adjust the vibration out. It's barley noticable, but the vibration is there and you can see it while its turning at eye level. High quality carbon fiber is a joy. They are smooth and do resist slight impacts BUT...if they crack, toss them. As stated earlier, they will blow apart. When I can FLY...I'm going back to carbon fiber. I can hover real good, but until the learning phase is over...PLASTI-BLADES. Just my $.02 worth.
