Yeah. Evenly placing the mass is a great way to get the overall mass distribution (the inertia tensor, for those who like the jargon) correct. But it's basically *never* going to produce an acceptable result if that's all you use. Most of the aircraft I did would tip backwards on their gear with the default masses. The idea is to place point masses at locations where you know the heavy stuff is (engines & payload), and then let the solver come up with something plausible for wing & fuselage masses. I believe it weights them according to their surface area. And, of course, there is always a final tuning stage where you move ballast around madly trying to get the aircraft to sit stably on its gear and still be able to lift the nose for takeoff. :) Andy _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
