RE: Welcome to Club SAITO !
RJ, I have always run a 13x6 Scimitar or a Bolly 13.5x6, the Scimitar would turn 9,700 on my old high compression .80. I used 14x6s on the Saito .91 when I had one briefly and 14x7 Graupner or a 15x6 Pro Zinger on the 1.00. I like to prop Saitos for mid nines except for the little .30 and .40. The .80 just can't manage mid nines with a 14x6 but I also only run 10 and 15% fuel. More later.
