I have a soft magnet an its i guess you could call it warped maybe. Its not flat is the best way to say it. if you look at the flight plate it is higher on one end and lower on the other. I thought i heard somthing on another thread about flipping it upside down and filling it with water and putting it in the microwave but that could be wrong. I really like the disc and hope i can flaten it. anyone have a clue?
