How do you tell if your 11x KC Champ Eagle is an L or X mold?

Just curious.  I've seen a lot of reference to both molds and when looking at my disc, have no idea how to tell.  Also, what is the difference between the L and X mold?  Do they fly differently?

The Eagle X has a notch out at the end of its wing. The L has a totally flat wing. The X will fade out quite a bit harder than an L and also handles wind better. If you know Teebird vs TL, it's the same differences between the Eagles.

Thanks for explaining that. I do have a Teebird and TL and compared them this morning. I see what you mean.
