RE: good second plane
My second plane was a twist 40. I learned on the mustang pts, so I got the hang of rudder input on take off right away. The twist is a blast to fly. I do have the throws turned down a bit as it responds REAL quick. It is very smooth on landing. with a slight head wind, you can almost set it down like a heli. If your into 3D, it may be a good option for you to look in to. Its also a fairly inexpensive plane.
You do have the option of a 60 version as well if you want something a bit bigger.
