The Flite Test Simple Scout comes with dummy engines; a nice detail. Thought it might be a good idea to paint them to set them off a bit from the brown fuselage and black cowl. So I went with aluminum Rustoleum. The skewers that come with the kit can be used to hold the engine parts while you are painting. I used sandbags to hold the skewers in place on the table. And then the skewers can be used again to guide the parts to the exact right place on the fuselage when you hot glue them. The one picture shows the parts painted black. Bad idea. It blends in with the cowl.
