On the larger props, I prefer wood, Beech to be exact and my preference here is Xoar. They retain their pitch. But for props that are 14" and under, the APC are the standard. And yes, I agree that MAS props have some good applications. Like when you do not want a prop to break. They are durable that way, and also some sizes were great in RC combat. But overall, if given other choices, The MAS prop is at the bottom of my list. Problem is, they are one of the companies offering a better selection of 3 bladers.
