This is true vicman, they do need some speed and are obviously not a 3D plane.
However Joe, don't think that this plane won't fly well at slower speeds, because that is wrong. The plane stalls around 15-20 mph, and I've flown in a 10-15 mph wind and had the plane going into it and had it at a crawl. Vicman is right, don't turn when you are almost at stall speed because the nose will fall. However, if you stall the plane straight, the nose just falls nice and easy and is very perdictable.
I surprised many people at the flying field with just how slow I can get her with the nose into the wind. And then full throttle and back over a hundred in just a few seconds. Wonderful plane!
