so, to have a plane you can "move" in a 3D space with authority you need to have command (almost equal) in the 3 axes that`s why I was say`n a boom does not make a 3d plane, you need SIDE FUSE AREA, and surely a profile have a lot (and flys good too).
To track straight and 3d too ... I think longer tails with massive surfaces are the solution ... like the composite arf yak 55sp, the plane of my dreams...
