I mounted my Pa 65 RE with Muffler in a Strega ARF, made some flights this weekend. The engine is running very well, but I did not find a good a prop. I tried a Bolly 3 blade 13x4,5 and one 13x4,5 2 blade that I bought from the Randy and was not good none of the two, I has to close to much the needle and the engine got to poor. I also tested one 13x5 but wooden Rev Up, was the one that was a little better. Which prop I must use?
Which size and pitch?
