Jim - That may be doable if I do it the same way I did this one as far as how the hangar wall is actually attached to the base. If you look at the link to my Gee Bee & diorama WIP thread below, you’ll see that the hangar has three brass rods (well, four actually if you count the electrical pipe on the front of the hangar) that slide into mounting holes on the base. It is tight enough that I can easily remove/replace the hangar repeatedly, so theoratically if I just made sure that the mounting solution was identical among, say, three different hangar fronts, I can definitely see the feasibility of having an interchangeable hangar front.
Geezer - If a larger one is made I will definitely do a WIP on that…
Bish - If you take a look at the build thread below you’ll see WIP pics and descriptions… hope that helps. Let me know if you have any other questions. It was actually surprisingly simple to make!
