I have a Calypso and am very happy with the soaring performance. In fact I have won two ALES contests with it. If not familiar with ALES, you get a 30 second motor run or up to 200 meter altitude and then thermal for 9:30 for a total flight time of 10:00 with a spot landing.
That at being said the Calypso does have its little quirks. For one with the reccomended 1300 mah battery it tends to come out nose heavy. I run a 850 mah pack. Having no down thrust it will climb like crazy under power so I have a down elevator mix while under power. Once in glide mode with the power off the Calypso has great directional stability, reads lift well and will soar with the best of them. I do suggest installing the flaps and using a radio that allows camber mixing to get the most out of it. The nice thing is that you can add those later after you become reacquainted with flying. I didn't like the black canopy and decals so I added a little paint to mine.
