Yes I do plan to play it safe and be happy its a 1/2A running in the low 30s which is leap past most of the engines I have on hand this size. I do have a AME RC carb version of the Norvel and another AME made for the Heli As an option in lieu of the long winded exhaust timing, I wonder if I can get by with a header pipe as by nature the tuned pipe stresses the engine more when on step with the engine. Im not trying to squeeze out rpm and can spare the additional strain on the crank and rod. Heres the pic of the simple header I matched up some metric tubing for a snug fit and coned the tip, should help with some of the noise. Bummer about your engine but wow 42k is screaaming got any of it on vid>?? Looks like I have the full .061 CS collection now.
