RE: RCV .91 CD & Matching prop?
I think the real problem with the three blade props is getting a good selection to try and choose from. Usually we are very limited as to which prop to use with three blade versions. But with the two blade props, we have a rich variety of different props to choose from and to use. Plus some brands tend to be not as good as some others too. so it is easier to have good success finding a two blade prop that works well with a particular engine and airplane. But when you do find a three blade prop that works with your plane and engine, you have a good combination, it can work really well.
