These are the small detail parts for the Hyperion 25e class P-51D Mustang RC plane. Included are the gun ports and the small fairings in wings (two on top per wing and one under). Notice that the parts can have some printing dust over them and the barrels can be filled with it. It is easily removed for example with a 1mm drill tip (by hand). You can either drill holes (be very careful and measure the spots precisely!) for the gun port rods, or cut them and just glue them on without the rods.
