The PAU prop is the same as a Xoar laminated. If you are running a plain beachwood prop give the laminated version a try, either PAU or Xoar (same prop) it will be a bit quieter, it will hold the RPM down a couple hundred but pulls just as hard. My 111 ripped the beachwood prop like crazy (I like the sound) but it doesn't with the laminated one. If you want to try the PAU go here, http://performancercaircraft.com/
