RE: Another 2nd plane question
A Pulse XT PNP would be good.
It's aerobatic, a lot of fun to fly.
However the PTS with all of the training aids removed can be said to be a great second plane as is.
Since you are already at that level you are really eyeing a "third" plane.
The sky is practically the limit.
Even a 3D plane would be good, provided you turned the rates down initially until you were very used to it.
I'd also say that you are ready for the Biplane.
I went from the PTS as a first/second plane right to an Ultimate Biplane w/o problems.
You are already used to tail draggers, know how to deal with yaw at take off, have done a good bit of sports flying, etc.
