I have been building my own P-47 ARF, and it looks very solid. I have installed Century Jets custom made retracts on it. I am using a Saito125GK FS engine on it, a bit overpowered but I was thinking doing a bit of Imac Basics with it as well. One problem arises which I wonder ifanyone could help me with. The remaining thing to do is to find amuffler to the engine that does not stick out of the cowling on theside, like the standard Saito muffler will.Does anyone have an idea of what sort of muffler tousewith this engine to avoid the problem ogf having to drill a hole in the side of the cowling and ruin the looks of the airplane?
