I was at PIAS today and bought a champion disc for $4. It is orange in color and does not have a name on it. All the stamp is a small INNOVA stamp in the middle surrounded by a "checkerboard" like foil circle around it. Any ideas on what this thing is?

Sounds like a champ whippet

I am going with Champ Whippet

Throw it. If it does nothing but dive bomb left for about 200', its a whippet. I had one of these discs and didn't know what it was until I threw it. All it does is dive bomb left no matter how much arm you put on it.
