RE: Saito shuts off
Visual looks the same on the smoke. A 12 x 7 is smaller than what I'm running on a 13 x 6, right? I know the first time I tried a 12 x 5 graupner full paddle and it went higher RPM than the 13 x 6. I have no idea of how used it is, bought it at a Hobby Expo a few years ago. there's hardly any carbon in the head or valve seat area. Really clean for what I think is it's age since Saito no loner makes it. So does the old rule of thumb for props work like this..... 12x5 would be 12 times 2 plus the pitch (5) = 29. 13x6 would then equal 32, so a tad slower RPM? If that's true, then the 12x7 would be 31, (less than the 13x6)? Also, I probably mis-spoke cause 3/4 to full throttle doesn't change RPM that much, I was probably at 3/4 or just a tad above. I don't know how to post a pic.
