The Apache has a blade to correct this problem as shown in the picture below.

You are correct in most regards except for one minor detail...
"some choppers have a trim plate or the tail is put into an angle to avoid this effect."
The angle of the tail really has nothing to do with anything in regards to functionality.
The ONLY way to totally eliminate the rear rotor is by using air propulsion that is used to counteract the spinning of the main rotor. It simply shoots out air in the opposite direction that the chopper wants to spin without having a rear rotor. Otherwise without the counter balance the chopper would simply cork screw itself.
