I have the uproar 60. I really like that plane. I build mine as a kit. When I built it I added 1 1/2" to the elevator and Rudder from the hinge line back and 1 1/2" to the ailerons from the hinge back. I did this after watching an uproar 40 at our flying field. I am really glad that I did because this plane is a real animal now. It hovers, Knife's and does several other 3D moves well. It does take some learning to get it to do 3D. Its not as good as most of the 3D Designed profiles out there, but in my opinion is does some other things better, smoother too. I have had my uproar 60 2 years now ant it is one of my most enjoyable planes if not the best 3D plane or best pattern plane. It is one of the most fun planes
