Glue these adapters and the magnet inside the tube on the model's base. This will help prevent the flight stand from rocking back and forth.

Extra Small: 3mm
Medium Small: 8m
Extra Large: 20mm
Mega Large: 25mm
All rocks have some additional margin to compensate for a magnet that shifts while being glued. For the Extra Small, it's around 3.4mm rather than the 3mm rod, for the large it's closer to 14mm.
