From personal experience with the Avistar, I like it because it has a semi-symmetrical wing. Most trainers have a flat bottom wing. The semi-sym wing will allow you to perform aerobatic maneuvers a bit better than the flat bottom. Before I get blasted - I have an LT-40 (kit) - and with enough power / correct prop I can do many different aerobatic maneuvers (loops with a snap roll at the top are kinda fun). The big BUT is that the Avistar will allow you to do them ''better'', more easily.
