Most likely you'll have to settle for a 14x7 or 13x8. Three blade selection is pretty limited so you usually have to compromise

Graupner 14x8 3 blade,there is none better. Looks good and pulls like a clydesdale. I have a Saito 120, I had a 15x7 APC on it and it was to much power for the plane it was in.I decided to switch to a 3 blade prop because all the know it alls said a 3 blade prop is less efficient. I picked the Graupner because it looks close to scale. The know it alls were wrong the Graupner 3 blade pulled just as much and because I went to a higher pitch the plane was even faster. I left the prop on though because it looks so good.

2 blade props = speed through rpm's. More lots of air through hi speed rotation
3 blade prope = torgue. move lots of air through low speed rpm's.

RE: 3 blade propelor for my engine
I have an .82 Saito and was wondering what is best. I ordered a MAS 12x6x3. My other choice is a 12x8x3. I have a 2 bladed 13x7 on it now while breaking in the engine and it spins that around 9000 rpm without being properly tuned yet. What prop should I put on it? It is going on a CMP P40.

Hi!
As I said earlier ...there is no substitute for a 2-blade prop.
You may find a 3-blade that works Ok but there will always be a 2-blade prop that is better if you look for it.
APC is a good prop. Ma is not!
