Hello guys, I'm a new member of the devel-list and new to FightGear too. I came from X-Plane and I have done some aircraft for this simulator ( http://xhydros.free.fr/) and I'm the webmaster of a french scenery site ( http://xpfr-scenery.fr/)
In order to understand FlightGear and especially FDM, I'm actually translate the "README.yasim" and to tune a little the DR400 FDM. Off course, I have some questions ;-) First of all : DR400 have a wing made in two part : inner without dihedral and the outer with 14° dihedral. Inner have an incidence of 3° at the root and -1° twist. Outer have an incidence of 2° and a twist of -4°. Actually, the wing is done with only one piece, 7° dihedral, no twist. Can I use the "mstab" command to specify the outer wing and the regular "wing" command for the inner one ? In the readme file, I read this for mstab : these surfaces are not involved with the solver computation these surfaces are not involved with the solver computation... I'm not sure to well understand. Second question about readme : I read this in the fuselage section: Factors for the generated drag in the fuselages "local coordinate system" with x pointing from end to front, z perpendicular to x with y=0 in the aircraft coordinate system. E.g. for a fuselage of a height of 2 times the width you can define cy=2 and (due to the doubled front surface) cx=2 Again, I' don't understand the meaning of CX=2 and CY=2... Thanks for your help ;-) Olivier Faivre >From France
