Buddy , FSW is do , while u had less wing span but u still had same maneuverable as a SW design , but disadvantage of FSW is to flow is come from outside to center of super structure it's cause Aileron had less effective than normal SW that wind go from inside to outside but to so the tip of wing has higher effective when turning or pitch it's made drag forward to the front make it pitch more angle in less time than SW design when to drag from SW is also high in just mid-to-rear of the plane Canard is need to made it more maneuverable , but do to lack of stong material the super structure and wing structure is need more than SW design to stand again wind at high speed but if u have strong enough material it's not a concern the concern is how we manufacture such a material . the SU-47 and X-29 is a Tech Demo of FSW in need to a challenger from both side US and Russia in Flight Technology but because of FSW has a small amount of Experience and Computer support design and knowledge it's hardly to make it's good Performance while SW design is R&D from a long time since 1945 but FSW had very little model and R&D , but currently all our jet is commonly SW design because we want it's speed to go faster when we doesn't had a strong enough material but when we had composite material than strong enough and easily to manufacturing and much more precise than currently FSW will get in and get more advance than it's had , but in space it's nothing to do with it. i say : in macross there even have a Thermonuclear Reactor and even Fold when we is just not even had real Prototype that can produce enough energy and we not even had a space frigate nor Probes that can survey around our solar system .
