Yea i think u right Richi i need too combine both... but i have trying a lot of thing and that not work =(

Suppose i use directly-->

my.pan += 4 * (key_a - key_d) * time_step;
my.roll += 4 * (key_e - key_q) * time_step;
my.x += 8 * (key_w - key_s) * time_step;
my.y += 8 * (key_c - key_z) * time_step;

So now when i change my PAN, it dont affect the movement direction.

But if i want the PAN affect the direction using this code, what i need to add?
