Spacewackers are good but sports-scale. Try your hand with a Tiger first (or its clones like those from Phoenix) or a Dolphin (Phoenix) or something like that. These are low wing semi-symmetrical airfoil airplanes and will fly like your trainer if properly setup

There is a sticky in the forum (first three threads or so in the page) telling what you could take at your experience level and that list is quite comprehensive
