That sounds great! Unfortunately I haven’t made any plans; I was interested if the concept would work before I committed to an entire project. What I was planning on was adapting existing f14 plans to my spec - if it’s just a model, that should probably be pretty simple as load bearing parts don’t necessarily have to be light or specifically placed within the airframe.
You could use wood for the core;that would work. I feel the wings would sag under their own weight if just room, so a plywood or aluminium spar would do it some good. For the canopy, watch the nnp39 build video and see how nerdnic makes his cockpit. I just used an old plastic wallet for my p39 but it has the same effect - it saves having to find a vacuum former, though if you’ve got one, that might be easier.
Let me know how your project goes though - sorry I couldn’t offer any plans!
