The 'A' wing is too much dihedral...the 'B' or sport wing or even a little less is fine. A good flyer and it will self-level enough to be a good trainer. Wind affects it less than the 'A' wing. If it's not too much trouble I would recommend changing. I learned with the 'B' wing, no problem. To check the washout (allso un-necessary) mount the plane on a stand or table, put small piece of anything (a checker or piece of balsa) on each wing tip in the same place. Now lower your eye level, as you look at the plane from the front, about 6 feet from the nose, until the checker disappears. The small pieces should disappear at the same time, if not the low one needs to be twisted up while heat is applied to the covering, until they are the same.
