Hi Fruiz1978,
If the N5c you have is the TT Edition (Torque Tube Version) then both the main and tail rotors will spin clockwise with the leading edge of the blades facing the direction of rotation.
If the N5c you have is the standard N5c (Belt Version) then the main rotor will spin clockwise and the tail rotor will spin counter clockwise with the leading edge of the blades facing in the direction of rotation.
Hope this helps, and if you have any further questions just give us a shout.
Cheers,
Ross
