If the blade rotation is just an offset and a rotation there shouldn't be any noticeable performance problem animating the blades as the animation rotation setup is quite efficient and to implement this is just adding 4 more animation transforms. FYI Setting up an Animation transform is more efficient then setting up a 'general' PLIB transform as they are 'special cased' and the matrix math has been optimized significantly. Of course this is assuming that determing the angle of rotation isn't an expensive operation, but I don't see why it need be.
