Gotta agree with Woj on this one.. My F-14 i would love to offer as a kit, but at the complexity level of it, it'll never be able to compete with a skymaster as mine will likely be more expensive, so the only way I can even consider competing with that model is by basically offering them custom built to customer specs.
That said, I am currently designing a new sport jet that will either end up composite or semi-composite, maybe even both for those who want to balsa bash some wings and tail feathers.
