Quite frankly, if this person is experienced enough to fly a biplane, orientation ought not be an issue. If a person is worried about orientation, use a spotter/co-pilot for the first few flights. With my first bipe, this was an issue, but as with any airplane, once you get to know it- orientation is no more an issue than with any other aircraft.

If your concerned about it, change it, but I wouldn't reccomend it. I personally like the view you have created from below!
