ORIGINAL: Luftwaffe Oberst
I run a 14x6 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

Evolution 3 blade ????????????
The only ones I've been able to find are the thing that comes on the Raptor and the "Evolution Alpha 60" 3-blade. That Alpha 60 is listed as a 12x4. That seems a bit small and flat to use on an OS91FX. All of my OS91s like the 14x7(3) Master Airscrew. They're on the H9 Spitfire, P47, and Corsair, and a Hobbico Sukhoi31. I'd tried the MA 13x8(3) that the OS75AX likes on one of those but it acted small. I can't imagine a 12x4 even coming close to applying the power of a 91FX, so what Evo(3) are you referring to and where can it be found.
