I have a shoestring, and I will warn you that her belly is very VERY delicate. I've totally replaced the balsa spars underneath with basswood.. It is a really beautiful plane, and is a showstopper. She won't do all the tricks in the book, but really a fun fly. I put a .91 Saito in the nose, and it has unlimited vertical. I love the plane, but have to say that it's definatly not the plane for people that have a rough landing once in a while. The shoestring is not very forgiving. BTW Even with flaps I was suprised by the speed on landings. Much quicker than my SE and Decathalon.
