I would think the Funtana was not assy right if it was just going level. 3D planes can't tolerate high speeds well though. If you want to learn hard core 3D it will cost planes; that is why most go with .40 profiles, because you can go through 2-3 at the same cost and most can be fixed with some CA and packing tape at the field. I have a .46 Ucan and it can do just about anything but it does not do it as well as the profiles. It is a plane that can do good at everything, but it is not great at any one thing. It really just depends on what you are after.
