Tail rotor? 
I really like the way you've done swashplate, but mostly this aircraft could be much better. True coaxial helicopter I mean

You can't yaw by varying the collective on the rotors, since the new blades have the forces applied at the root, so more drag doesn't require more torque.

I've tried to put control surfaces on the blades, it made it a little unstable and even if they were kinda working, SAS is not affecting the KAL controllers so if it started to yaw, it kept yawing (like trying to fly a spacecraft without SAS).
