I like seeing new ideas and modifications of old ideas in your work. Where, or more accurately, what kind of shop does the photo work for the pieces you use on throttle, elec panel, etc.
That idea works well. At present, I am building an F11C-2 from a very old plan. At the time the plan was drawn, controlline model fuselages were often carved from a large balsa block. Since balsa is now very expensive and I have no desire to whittle on a large block, the templates were used as patterns to cut formers and bond them to a central keel. As you can guess, the plane will have to withstand "normal" flight stress and landing, therefore much of what you put inside yours would be too fragile. When I run into an obstacle, I usually postpone the next steps, so watching you may solve some problems.
