Carbon blades don't flex as much due to the weeve.

Wood blades may have different CG depending on the wood grain.

The other advantage is where wood may warp due to humidity Carbon Fiber will always retain it's shape.

During a crash Wood blades have the advantage they disintegrate faster saving the rest of the heli.

At very high RPM's some wood blades are known to eject their lead weights.

Woods have a weight advantage and a cost advantage so it's up to each flyer and their own flying style to decide which is best.

I remember before the 450 pro came out the Align woodies were very popular and many would ring it out with them. I think if your just a beginner woodies will work just fine, just don't use too high of a headspeed.

There is a company out there called www.stealthblades.com You might want to check their blades for a 450 class heli. I had bought several for my Mini Titan and they are good. Besides at $13.50 a set they are much cheaper than the woodies. Once you make the jump to carbon there is no going back. They are much better.
