Thank you for the thoughtful reply. It sounds right on in every way. BTW, I sent an email to Great Planes and they contacted the designer. His reply was that the toe in was intentional and that it is there to provide added lift in KE flight. I have mixed feelings about that. If the KE flight has a high AOA involved, the bottom SFG would be providing the lift I think, and that sounds less stable to me than if the top SFG were providing more lift and "holding the plane up" rather than "pushing from the bottom", the plane up. What do you think? and thanks!
