Heli_dual flight dynamic model issue

as the follow shows,the lateral_x_force and lateral_y_force is not calculated in heli_dual frame.it will mean that the lateral_x_force and lateral_y_force still be 0.compared with heli_frame_conventional and heli_frame _compound,it does not seem logical.would you like to give some suggestions?thank you.

@justinwang666 the rotor dynamics for the conventional and compound are based on models developed from actual flight test data. I don’t have a way to develop a model of a real dual heli. I suppose the rotor model from the conventional heli could be used to develop a better dual heli. The dual heli was a very basic model just looking at forces and moments similar to how they are developed for a multicopter.
