RE: Goldberg Extra 300
Yeah its a slimline pitts muffler OS 1.08. Cowl is from stans fibertech and extended for a pitts muffler. It is all inside the cowl and needs no cutouts other then the exaust stacks and head, needle. The prop is an APC 14X10. I only have two flights on the plane yet but the performance is outstanding. I belive it is goign to be the best flying plane i have had my hands on so far.
