Sadly, many of the planes out there clearly marketed for beginners actually require a knowledgable and skilled pilot. Before you quit, I would strongly suggest you seek out local flyers (either a club or informal group) and solicit their advice. Learning on your own can be done (I'm living proof) but can be much more expensive than learning with some help (again, I'm living proof

). If your hobby shop is anything like mine, they may not even know they sold you something that's hard for a beginner to learn with. That's why I mentioned that you should find local
flyers. If I lived about 2,500 miles further west (I'm assuming CA means you live somewhere in Cali.) I'd offer to help get you set up myself, and I'm sure someone nearby can give you some in-person help. Whatever you do, don't give up yet.
