From a beginner's perspective the performance of the various prop materials isn't the real issue. The real thing to worry about is durability. If you are beginning and learning to fly there is only one choice. Nylon. Wood props will break and shatter if you even THINK about touching the runway with them. They shatter very easiy and do not stand up to any type of abuse whatsoever. If you go with wood props you had better pick up 10-15 of them to get through your training. Nylon props will stand up to the abuse they are going to get while training. You're going to have plenty of dings and dents on the prop while you train, and for the most part the nylon props will take the licking and keep... well, you know the rest. You can usually get through your training with 2-3 nylon props.

Out of the nylon props available it's been my experience that Master Airscrew props seem to take more abuse than other brands.

Hope this helps
