By George, I think I've got it!

vec_set(vAhead,vector((key_cuu-key_cud)*50000,0,0)); //feed keyboard into engine.
phent_addforcelocal(me,vAhead,NULLVECTOR,my.pan); // Now apply physics force in the directions it is facing....
Lol, I also noticed in the above code I posted, I was using if(!key_cul | !key_cur) for torque, instead of the normal way. Ironically, that actually works, because pressing one key turns its value to 1, thus causing the torque vector to become a positive or negative integer.

But I am going to fix that. Just thought it was funny that I did the torque wrong, yet it still worked.
