The U-Can-Do 3D is a great plane. There are about 5 at my club, many of them are second planes. It will fly well (sport) with a 46, though maybe not do the best 3D. Drop in a Magnum .70 four stroke and it can hover nicely, and do anything you ask of it. You can kill the throttle anywhere in the pattern and gently come in for a smooth landing - it flies very well at slow speeds. I guarantee you will love this plane.
