Go to this website and find the page for "Charter" AMA clubs. You can plug in your Zip Code and find club fields near you. They will have instructors that will help you learn (free). You will have to join the AMA $58 per year, but you'll have liability insurance. Club fees could be another $25 to $125 per year.
The glow powered planes are NOT toys. They're powerful and fast, and have killed people that they've hit. Don't risk that.
By the way, welcome to RCU and RC flight! You're going to enjoy it.
