There are lots of great reviews about the Pulse being a good second plane.

I just went from the Nexstar to the Dolphin 40 (Phoenix models, from Tower Hobbies, $99), and it's a BLAST!!! I hear it flies a lot like the Pulse, but it looks like you want 60 size, so Pulse would be great.

My suggestion is to make sure you are using your rudder in turns, for take off, and for landing. Flying the Nexstar made me look like a great pilot. Now with the second plane, I see that I need lots of work, mainly with the rudder. It is a very important tool for proper flying (not letting your tail fall when you make turns, etc.)
