I was thinking of doing this myself. I was going to place a magnet under the carriers in the void space and then superglue a ferrous metal wire to the underside of the planes. Has anyone tried this. Is it not enough to make the planes stick?
Ive never tried it but I think it will work. You will need those 3mm hobby magnets, not sure if they are Rare Earth or not. They do an excellent job at holding tank turrets in place so its not a stretch to think they will work in your application.
