(Yes that cruiser is basically a flying wing, and the N1 would be sooo cool, whos gonna build the next? I must admit, with each design of ship, many new problems will occur, these ships were definetely not designed for flying!
The verticle stabs i used were big enough, though the bigger the better. I angled them out a few degrees, on my brief 'flight', they improved handling when angled. GO-RC, im not sure, but maybe those verts are a little too small?
So are you going to paint it once it flys, GO-RC? I suppose you could use your plan and print another to stick on top of the falcon?)
I kind of would like to see one of the land walkers fly. If you could do that you are truly a real aero engineer.
