I have the 46 sized U Can Do. Mine has an OS .46 AX in it. There are actually 4 sizes of this plane. The smallest is all foam and is a 3D parkflyer, all electric. Then there is the 46 size, 60 size and finally the giant size. I've seen all 4 fly. I can tell you that the U Can Do will land easier than a trainer!!! Get the 46 or 60 size with either a 46 or 61 size engine. Once your used to flying it and are getting the itch for doing some wild 3D, put in a 4 stroke like the .72 or .80 size for the 46 and 1.00 or more for the 60 size.
When you get one, keep your control throws at minimum and add expo on your radio. It will keep the plane from being too sensitive while you get the feel of it. The ailerons on this model are quite large!!!
Another candidate for 2nd plane is a Goldberg Tiger 2. I also have one of these (my avatar). They fly awfully stable and make a great 2nd plane.
