Dave,

I'm sure Great Planes can get you a replacement or, if not, there are 2 or 3 companies that make replacement fiberglass cowlings. I'm drawing a blank on a name right now, but just do a search on fiberglass cowlings and I am sure you will find one. By the way, the Aeromaster really looks best w/o that fiberglass round cowling. When it was originally designed, it had a fuselage designed like a small pattern ship and biplane configuration. So, the engine was cowled in nicely w/a spinner. If you need anything else on the plane, let me know.
