Well, so far I have only had a chance to run my engine once before mounting it in a Phoenix Models Decathlon. The airframe calls for a 46-55 2c so I am hoping that the gx10 pulls it along nicely but not expecting unlimited vertical either.

Anyway, the question that I have for you guys has to do with my cowl opening size and exhaust area. This is my first gas engine and I know that they tend to run hotter and need more cooling than equivalent glow. I have the off cylinder side of the cow set up with a baffle to direct incoming air onto the engine and the cylinder side opening has been opened up some to un-shroud the carb venturi. I am going to include some pictures. So do I have enough of an opening or should I do something else to the cowl? I really do not want to overheat it.

Thanks
