RE: Welcome to Club SAITO !
Bill, I'm not much for staying inside the fence or on the tracks, sometimes you just have to do things because you can. The engine barely sips the Diesel fuel with that prop and it makes lots of wind.
Barry, I like Graupners a lot, that particular size (12.5x7) 3 blade represents a much greater load than the Graupner 12x8 3 blade, this is a mystery to me but it's a fact. My Fox .74 Diesel turns the 12x8 at about 9,400 but struggles to get the 12.5x7 to 8,000. The Saito .72 turning the 12.5x7 at 7,600 is durn good power.
