RE: Second Plane
I would stay away from all that you mentioned. I good friend of mine "had to have" a F90, and it was a very big jump for him to go from a trainer. It is very easy to fly, and can be very gentle, but it not forgiving at all. It is not very robust, so it won't take much abuse, hard landings etc. The biggest change for him was realizing that the F90 needs to flymuch slower than his trainer. He still is struggling with it. I think one of the " UglyStick" planes might be a better choice. A Tiger 2 or one of the Sig 4 Star planes would also work well. Good luck
