Personally I can't say enough good things about the SE, it was a great second plane for me. My son just got signed off flying his SE cause the trainer we were using was the clubs and we had to give it up. 3 flights on the SE and he got signed off.
I have a 4* 40 and I don't like it nearly as much as the SE, just personal preference and flying style I suppose. I think what is more important than everyone's opinion is honestly evaluating what kind of pilot are you? I have seen people that are moving on to a second plane that think they are "ready" and I would not have signed them off if I were there instructor. On the other hand, my son for example, continues to amaze everyone at the club as to the natural ability he has to "see" and "feel" the plane............
A great second plane that in my opinion can do everything for your confidence, take away ALL fear of doing inverted flight, and some aerobatics...........the ZAGI 400X. Stuff it in the ground?????? Oh well, pick it up and throw it back in the air.....best of all when you get comfortable with it you can probably find a local group to fly combat with
Anyhow, now you got my .02 as well
