Correct me if I'm wrong guys, but a 10 pitch prop is quite a bit below the recommended pitch range for the SP series engines isn't it? I presume that by going up in number of blades and diameter that this is making up for this lower pitch? As I recall RCV's recomendations are for 12 pitch props, which is why I wanted to ask about that...

But hey, if it works then fly it right? [:-]
