what all up weight are you getting with the 40cc? mine with the 3W 28 was just over 12lbs. i sold the plane to a budy less engine and he installed a YS140 sport and now i have it back. haven't put it on a scale yet but it should be at least a pound lighter and man what a differance. it flew great at 12lbs but lighter is better. i'm thinking about selling the YS and going back to a OS 160 with a pipe but i would love to run a gas engine.
