No it does not matter, BUT, it's supposed to spin the opposite direction of the main rotor, like if the main rotor is going left, the tail rotor should be going right
The main rotor creates drag which makes the heli want to spin - the tail rotor pulls the heli in the opposite direction to compensate and keep it steady.
Look at the angle of the main rotor in regard to the direction it turns - you'll see how it 'pulls' upward. The tail rotor will need to 'pull' sideways, according to whichever direction the tail rotor is spinning.
I'm assuming you're reattaching a tail rotor or rewiring a motor?

Yes - it matters for any heli.
