I just ordered this from Tower Hobbies:

The representative told me that it will fly well with a 46 AX, but the 55 AX would be ideal. It is a 3D capable mid-wing, and has a large flight envelope, according to the manufacturer. It won't be as prone to flutter as the U-Can-Do, yet performs the maneuvers just as well according to their video in the link.
