I have a .60 size ultra stick, and it is a great flying little airplane.

The only problem is that landing with flaps is so easy that it is easy to develop careless habits.

The crow configuration is fun, too. Crow is ailerons up as spoilers, and flaps deployed. You can dive at the field from a hundred fifty feet, pull horizontal, and set her down slow and close.

With the full span ailerons deployed it has a stunning roll rate.

One of the best fun flyers I have ever had. It does it all. With a .60, it moves right along.
