Spacey,

actually I fly a lot of gliders ranging from 1-4.5m wingspan. Either on our airfield with glider towing or a winch, or on some good slopes in the surrounding.
As you said, AFP was already good in simulating the slopes. But the behaviour of the tow was not perfect (too elastic I think), also the difference between small and large gliders when hitting the turbulence.
But the developers will continue to improve the flight model. They live in the same town and sometimes come to our airfield. It's now included in AFPD, called Rottenburg scenery. Dion seems to prefer this scenery as you can see it very often on his screenshots
