If everyone is putting Sato .82's on their ucd's and adding weight to the nose to get the ballance somewhat right, why dont you put a O.S. 70 on it and not add any weight and increase the horsepower???
I say this from experience
Are you guys big four stroke lovers? If so then I understand why you are going with these engines over two strokes. I've added no weight and have unbelievable power with my OS 50 Heli Hype.
