I built a Sig SE and have been flying it all season. I went from a trainer to a World Model Sport 40. I flew that all last year. I also have a Zagi 400 which I have been flying for 2 years. I think the SE is not a good second plane. I think a 4* of the WM sport 40 would be much better. Landing slow is not always a good thing. When you go from a plane that is very stable then go to one that floats in and if I even think to put up elevator or an aileron adjustment on a landing and have it really respond, you won't believe haw responsive it is. I would have been out of my league on a SE if it was my second plane. The fact is most people I see at the field that have soloed go out and get a second plane straight away. They get it together and start to fly it. Most are not ready. Yes they can fly but still lack in skills. I was that way, but the plane I got helped me learn and did not scare the crap out of me. If you have the money, go ahead and get a Cap or a SE or something very aerobatic. It may survive. You may do well with it. The advice that you got above is a better way to go. Fly your trainer until you can do almost anything with it. Then ease into a less aerobatic plane. I love my WM Sport 40. I fly it often. I don't think of it as a bad choice or a compromise. The fact is if you are in this for the long haul, you will acquire all kinds of planes and diversity is part of the fun of it. Take your time, have fun!!
