I too should have recommended checking with your local club and instructors to determine what buddy boxes are being used. When just starting out this is really an important step. Would also recommend that you not try to learn alone. The result of having an instructor will save you much frustration and most certainly your airplane. Don't go it alone. That said, I think you will find the above recommended model is a fairly common product used as a first airplane trainer. Futaba and JR are the most common radio and receiver packages and most fields will support both. The benefit of first checking with your club is to determine what the majority are using. This way you are more likely to get help from people when needing answers to your questions.

I had a guy show up at the field one time with a plane that didn't have ailerons. The nose wheel and the rudder were connected to the left stick. Arrgh. I couldn't fly his airplane to test it out before instructing. I tried to taxi the darn thing and just couldn't make the mental switch to the left stick for rudder and nose wheel control. Needless to say, this limited the guy on finding help.
