I am Considering replacing my GSC propeller and I am not sure weather to replace it with a two blade or a three blade propeller. Which one would be the best to use for performance and idle vibration. It seems to me that a lighter two blade would work the best for the idle vibration problem that I now have but will I sacrifice performance? Any and all opinions are appreciated.
