I just started flying my escapade inverted. It has an OS FS 52 Surpass. From the beginning i have been flying the escapade with this engine setup on the rich side. engine smokes good in the air. good power. climbs nicely. Couple weeks ago I started doing more inverted flights. I noticed when I flip the plane over I see more exhaust smoke. the engine sounds richer - much richer. I feel the loss of power. I figure becuase the engine is now inverted that the glow plug is getting cooler with more fuel. Am I correct? does that mean I can lean it out some more or should I just leave the carb setting as it is?
