I agree with tychoc, purchase an ARF and get in the air. Decide what you will probably like for a second plane and start building it with no pressure to hurry. A slightly sportier high wing or a low wing trainer (Goldberg Tiger II for instance) could be a good second plane. This will all depend on how well you do with your trainer prior to it's possible demise. 6EXA or 7c series radios (or equiv in other brands) will have all of the features you will need for some time. Along with the extra channels are the elec trims, EPA, mixing and sometimes just the way it feels in YOUR hands. I think the AX is better than the Evolution but to some that is arguable too, either will work for many planes down the line if needed. I have always been a kit builder myself and enjoy it, but it does take time to do right.

You've made some choices, time for a couple more.
