Nothing to do with Stuart's work on the c310, but a tip on the fdm (jsbsim version):
Move the CG forward a bit, at least a 10--15". (the correct CG location should be taken from the type certificate, which I haven't been able to find on a quick google) The plane flies a lot better then. (better stability and cruise alpha, when it's not flying on the stabiliser) This also puts a little more weight on the nose gear, so it steers better while taxiing. As it is now, the CG is actually aft of the lift. (AC_CGLOC is, if I understand it correctly, the CG location without the AC_POINTMASSes, i.e. empty plane?) A blind guess on the CG limits would be something around 15--35% of MGC perhaps? Outside the scope of the lift and drag definitions (due to alpha) tables -- as when stalled aggressively -- the plane behaves strangely, of course. But it's not certified for acrobatics. ;) _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
