rrragman,

You are right a norvel .074 might be a good substitute for this plane. I never forgive my self because of 2 things. first because of the norvel I had and sold it with its plane ( a piper J-3) and then because of a Cox TD .051 with RC carb and muffler with its plane ( again a piper J-3) I didn't buy it.
