I'm with you Dave on the Master Airscrews!! It seems like APC has a cult-like following, with people looking at MAS with disdain (typical comment= MAS is only good for paint mixing) and never conceding that it might possibly be the better prop. I think the "high-tech" shape, the pointy tip, and the pretty grey color are mesmerizing to them (I like bright and shiny objects)!

I have noticed with my Shrike and Diamond Dust that the planes run at least as fast and probably faster with MAS versus APC (same pitch, same diameter). Plus an APC tip is SO easy to break, the slighest touch with dirt or pavement and POOF tip is gone. With our Shrikes, Whips and Dusts landing in the grass, it just doesn't make sense to go with APC.
