I run a 14x7 3 blade with my O.S. 91 FX Ringed and my plane flys very well with it. I love the looks, the sound of the prop wash when I do a slow fly-by. And the whine it produces when I do a high speed fly-by with it. The Evolution 3 blade has more of a breaking effect then my Master Airscrew 3 blade. My plane does not slow down like my old PTS did when I cut the throttle. The cause of this is the width of the blades on the Evolution. It's designed to slow the trainer down for landings, where as the Master Airscrew it's designed for preformance and scale looks, rather than just for training. JMHO
