Hi,

I have been runing my saito .50,s with a 12x4 and the new saito .56 I just broke in with a 11x7.5 master airscrew and set the needle with a tac. to 10,000 rpm's. The 56 runs great and idles down, well below 2,000 rpm's , eveyone coments at the field how well its running and responds.

One thing , in all the saito's I have had . I set the valves before running, check them half way though breakin and reset the valve clearence after break in. Its real important to have the valve clearence set properly.
