Hi Gérard, very nice work. I will do what I can to assist you with the FDM. I found information about the airfoils, but not much more. If you have any information about the rotor (geometry, weight, rpm, cyclic and collective incidence, c.g. of the blades, what ever ...) and the fuselage (position of the c.g., inertia tensor): please let me know.
