Thanks guys!
to walker: there isn't any trick here, I just bought the magnetic levitation base with a floating globe. throw the globe and find a neew magnet with the same magnetic force as the base. Then put the magnet inside the kit balance point.... that's it!
The electro magnetic field generated from the base will lock the magent (or the kit) at the center of the base.
I have tired on 1/72 F-16 before as well.
