If you are looking at your second airplane, you should start looking at whether you are more interested in pattern or 3d or just sports flying. For sports flying, consider the Tiger 40- its easy to fly and handles similar to the trainer. For pattern, the Escapade, supersports etc are good airplanes but not all of them come with cowls. You will get cowls in 3d airplanes like the Reactor 46 and UCD 46. In these airplanes, if you set low throws, they will fly just like trainers. In the Reactor, you can do pattern and sports flying as well as 3d with higher throws. 3D airplanes are built very light though
