Saito 56 Prop size?

What props do you guys use with your Saito 56's?

Hi Crist.

There is a wide variety depending on the sort of run you use. I used a fairly big venturi (about a .320) and so the engine ran at about 10,500 RPM on the ground. Consequently, I used a 12x4 3 blade Bolly or Eather prop. My buddy Pat Johnston used a 13x5 and 13.5x 5 or 6 B,Y&O with some success on a somewhat smaller venturi and a ground launch of about 9,000 RPM. These engines need to be loaded a bit.
