Had a setback last night. I had made up the exhaust pipe/shroud assemblies, drilling out the pipes and reshaped them to look better, painted and weathering them, then went to put them on and I dropped one on the floor. It bounced who knows where. I spent over an hour looking for it with out luck. The thing's about the size of an air rifle pellet. I'm hopping I have a extra from a Hobbycraft P-40C I made a few years ago.
