One word -- SPAD
Though I do not advocated going it alone, and I highly recommend that you hook up with a instructor that can work with your schedule.
But-- if you must be self taught, a simple spad trainer will be MUCH more durable, and cheap to fix or replace when the inevitable crashes happen that you will have going it alone. If you build your own SPAD, repairs will become a "non event" money wise compared to a blasa trainer. Check out the Spad forum here on RCU. You can find lots of info and links to invaluable sources of SPAD plans etc.

Again, I am not advising you to self train, but at least with the SPAD you wont be destroying an 80 to 150$ kit every time you learn by your mistakes. Balsa planes + no instructor= an expensive learning curve, usually resulting in frustration and walking away from the hobby.

Good luck,
