I've got the kit version I built 4 or 5 years ago using an OS 26 and it's a good (not great) slow flyer. I don't look on either the 25 or 40 size as a good trainer since they're taildragers and not a windy flyer for a beginner. A plane such as the Avistar trainer offers better handling on the windy days. If you like their style, then save it for the second or third plane.
