Ah-Ha, this accounts for your "Clear Sprue" question a few days ago .... Clever man, planning ahead like that
With 144 scale, you might get away with the smallest (1/16") acrylic rod. I've tested by simply taping the parts to a rod and seeing if it bends or not. You could do 3 ships with the rod going straight up(down) into a base, then make an upward curving one but where would you mount it. I'd be thinking of an L-shape bookend or such. You could do all 4 rods out of the vertical part or 3 from the base and one from the vertical. There are various ways to attach aircraft to the rods (see all Bruce's pix). I always prefer my rods to be pointing backward, at an angle, to aide the illusion of flight/motion, much like to common Airfix plastic stand does.
Should be very interesting !
