ihphobby This model is no longer available in the brittle FUD material. It's now available in the new Hi-Definition Black Acrylate material, which is smoother and stronger than FUD.
ihphobby @shurlock1The material is a bit brittle. The shell is a little thinner than we wanted because N scale mechanisms are large. So, you have to take a little care in handling it. Use super glue to put it back together.
