Okay, you need to start a new thread. Specify that you are GOING to learn by yourself, and that you are GOING to use a cub. Then describe the Cub in detail, the engine, and your radio. Then ignore all the advice about getting an instructor and using a buddy box, some people will have advice for learning on your own.

You will need it. The cub is not as forgiving as planes that were designed for the training purpose, and (like all taildraggers) has some taxiing issues you will need to deal with.

By no means should you start with a Duraplane. The only thing it has on the Cub is that the repair parts are cheaper. My Sturdy Birdy (same thing, different brand) was not all that easy to fly, even after I solo'd. Nor was it all that sturdy. The Cub will fly slower than the Duraplane, and that's a good thing for learning.

Oh, and anything you spend on a computer flight simulator will be money well spent. You can learn a lot about RC takeoff and landings before you acquire your Cub. You can also use it later, to learn inverted flight, axial rolls, etc. without risking the hardware.

Good luck,
