Did you try the 'exercise' I am describing ? "For example use the "Tower view" and zoom enough to get the details. Take off and stay 100 ft above the ground. Now push the elevator violently aband you'll notice that the nose keeps its distance from the ground but the aircraft body gains height. Compare this to the default aircraft." No, you didn't, otherwise you would have noticed what I mean. Please differenciate: I'm not telling anyone _where_ to tune the system to get the phenomenon fixed, I'm simply telling that there is "room for improvement", because the aircraft definitely rotates around its nose when you look from outside. I _do_ have eyes that are suitable to verify this, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
