Tai Ji 60 from World models is ok, and has retracts. It flies ok on a powerful 60, but really needs a 90.

Of course, you didn't say anything specific other than the calypso (goals, what you want out of this plane etc) so it's a little difficult.

The Widebody 60 from CA models is pretty awesome too, I have one I'm finishing up as I type. I haven't flown it yet so I can't give a definitive yes or no, but so far so good. And it's a kit, and pretty inexpensive too. It needs a few minor mods to be a pattern only plane, but those are very very simple to do.

Just pick a design that lights your fire then fly it and trim it to your liking.
