I'm not real sure what the style of ailerons has to do with it, but I am definitely a fan of the semi-symmetrical wings along with a floaty design. What most of us would consider a traditional trainer (Kadet, et al) was designed for flying around in circles on 3 channels and being as slow as possible on calm days. They are incredibly good for that, but the limitations are pretty big. My point above though was more of a training philosophy than a point on equipment selection. I think if you can't do a loop, a roll, a stall turn, and hold inverted for at least a few seconds then you aren't really trained to fly RC yet.
