Currently I'm flying an aerobird challenger (which I do not reccommend to start with). I've found quite a few things in the aerobird that I'm not very happy with. Feeling that it's time to move up, I'm faced with the 3 or 4 channel question. Should someone new to R/C, just graduating from the most basic of trainers jump right into a plane capable of A/E/R/T control or should one stick with a more basic model that only offers E/R/T?

R = rudder
E = elevator
etc...
