Thank you for the reply. I know the slope lift is very real even in the current AFP. I usually go play on the hangliding scenery and they do use the slope geometry quite well to calculate slope lift. It's great fun. I haven't had much luck soaring thermals on it though but there is a good chance that I just need more practise with it. I hope they made the planes react a little better when crossing through a thermal. I couldn't get the old one to show the lift like in real life, like a wing dropping. It does show the glider dropping the nose and picking up speed though.
