RE: inside look at 60 novarossi and OS 61 sx-h engine with nelson AAC sleeve and piston
the brass sleeve is from the Novarossi C60F side exhaust engine and same for the knife edged rod and cut skirt piston. the porting is elaborate compared to my five port rossi 3+2 engines, the turbo cut and knife edge crank is from the Novarossi as well.
I installed the AAC Nelson setup in the OS SX-H engine today and will run Tuesday, and fly Wednesday, I set deck height at .017 which is stock deck height, i have several of these engines NIB, my other one with nelson muffler runs 11x7 well over 14,800 on the bench on powermaster 15 percent fuel, with 158 degree exhaust timing.
