I am not sure there really is such a thing as a low wing trainer. All of them are a bit touchy. However, you might take a look at some of the World Models ARF's distributed by Airborne. The Rambler is a very good value at $59 and the Mustang is a superb flyer at $79.

Another one to consider would be the Great Planes Mini Super Sportster EP http://www2.towerhobbies.com/cgi-bin...?&I=LXHSR6&P=0
