Default 3 Blade prop for Sai .72

What three blade prop would be best for the Saito .72. A Master Airscrew or the Graupner ones. It is a scale airplane.

A 12-6 should be fine

Enjoy

Hi
I've used the Master Airscrew 12x6 for my OS.70, works well and looks great. Though you can feel that it has a bit less power than an 13x6 two blade APC.

I have run a 12-6 Master Airscrew on my Saito .72. Not quite as good as a 13-6 2-blade, but works OK.

The MAS and Graupner props are made different. The blades are wider on the Graupner whereas the MAS has narrow blades..

You best try each one and decide for yourself which one you like?

Enjoy,

Jim

I think u must use 13X5 3bale instead of 12X6, if using 13X6 3 blade, cause when i used 13X8 MA 3blade, it had same thrust as 13X8 2blade, and more speed. if u remove 1 pitch and will use 13X5, u will have bittttt more speed and same thrust, if not more
