Hi Fabio,
When is the first flight of your ufo? ;-)
I must say that magnets always had my interest too. Specially that transformercore with a magnet build in. Maybe 1 day i will setup such test. See if power pulse in equals power out or even more?
Mono pole technic or magnetfield bending might bring also some options for magnet motors....
Have fun and enjoy it, mainly. Its a nice voyage :-)
