create a seperate set of rotor blades as a model. Find the top vertex of the helicopter model or a vertex to attach the rotor blades too.
Then create an action that snaps the blade model to the helicopter and rotate it by changing it's pan angles.
And what if helicopters rotation changes? It will not work..
If you want this to work you need to use:
c_rotate(ENTITY, vector(pan,tilt,roll), USE_AXIS);
