This is a club that is in Olathe, which I believe is not too far from you. They have training every Tuesday; this means someone will connect to your radio, take off and land for you, then flip a switch and let you fly. If you screw up, they flip a switch, take over and fix your mistake, and let you fly again. When your comfortable, then you can take off and land, and eventually not use the 'buddy box'. This is how you learn to fly rc airplanes, the right way.

here you can enter a zip code to find a club, maybe there's one closer.
If you're having a tough time, don't get the P51; you should get a 'high wing trainer'. These are better for learning because, since the weight of the plane is below the wings, they have 'self righting characteristics' - they want fly right-side up, as the weight of the plane wants to hang below the wings.
Simulators are great for understanding the orientation of the plane; when the plane is flying away from you, it's easy to bank right/left, etc. When the plane is coming at you, things are a little different; this is where Simulators are great. There is no substitution for the real thing.
Glow planes give you more flying time, and can be set up to fly slowly, depending on the plane, the motor, the prop, etc.

This is a link to a nice, big trainer that will use the .58 you already have, is relatively inexpensive (for planes this size - bigger planes are easier to see in the sky), and easy to fly.
