I built a really small flyer, to small for docking ports, and I put a bunch of them on a big plane and took off. I had to use radial decouplers and when I detached the decouplers were stuck to the flyers. The flyers were so small it threw off the balance. I think we should have radial seperators. Like the seperators we have now but for putting stuff on the side of the rocket or plane. that would be really helpful.
