I no longer compete nor take models to shows. Some models I've built in the past are in a display case, but not very many. I have severly cut down my stash, especially of smaller, easily built models, and have concentrated on those that offer a significant amount of detail and are of historical interest to me. At this point, I consider adequate display space a priority along with my limited choice of models. I really would like to show off a model, like the Felixstowe and my other Wingnut Wings builds, in my home, so I will have to budget for additional protected display areas.
Although I'm sure the Felixstowe can be built so that the wings can be removed, I don't plan to do so. Once I finally get it done and on display, it's going to stay there.
I recall a modeler bringing in a fully rigged HMS Victory in a large scale to one of the IPMS Nationals I attended. Two men carried it, in its display case, into the competition room and placed it on the table. I'd think the same would have to happen with a built Felixstowe. I wouldn't want to be jiggering the rigged wings in and out of that model.
