If you can fly a basic trainer that has dihedral and are fairly confident with it, then don't be worried taking on a flat wing sport plane. OK, they are not self correcting. But you will be amazed how honest they are when you are flying them. And that's the thing that's great about them. My first flat wing (no dihedral) was the SPAD Debonair, that I built with no dihedral. And once I got it up in the air, it was great. But yeah, don't expect self leveling abilities.
