Rc,

Don't laugh, but I like my OE yellow blades !! LOL My T-rex fly's very well with 335 or 325 woods but I didn't do so well with the 315 woods. I highly doubt that a 430 or 420 motor will outspin wood blades , but that might depend on your gearing , battery , ESC , ect. I know that Techmodelproducts has 335 woods for a great price but have not yet tried them. I like the idea of CF blades but between the price and basically strapping a guinsoo to your T-rex , its a little scary !! I've heard a few horror stories about blade CP's with CF blades taking chunks out of things. I do not have a ton of experience but if you like the yellow blades you might like 325 woods. If you haven't tried wood blades yet , you do need to know your Heli will get a little touchy with the lighter blades. I've got expo turned up on mine , takes the edge off.
