Hi -
That's the same year range I belonged to SCCMAS although I left in 2010 I think. The guy I was working with was a retired fellow - Kent Kollings (if I remember the name correctly). Great guy...great teacher. We tried about everything to get my OS to run. Pretty much ended up overhauling the entire carb. Sometimes you just get a dud, I guess. He kept telling me that it was "loading up" in the air; yet it ran fine on the ground. We tried different props, different plugs, different fuel. She would start easy and seemingly run fine but nearly every time she'd die in the air and I'd dead stick'r in.
I've never owner or run a Rossi, but I've heard plenty of good things about them. Pretty pricy $$ though. I'm looking at an OS 40 4-stroke (older Surpass engine) and also and older Enya 46-4C 4-stroke. I had been looking at the OS 56 alpha as well.
