A guy at out field built a beercat stock. I cannot remember what motor he had on it, but it flew very very fast. No bad habits, but it was quick. He came across the field low and inverted, and became disoriented from the speed, and boom, rekit.
It flies quick. Depends on what kind of biplane you want. It was sort of a pylon racing plane, if that makes any sense.

hope this helps
