clockwise or anti-clockwise? is it the same or different with french built ones?

It does depend on the make and model of the helicopter. When looking down on it from above, most American helicopters spin counter-clockwise. European and Russian helicopters usually spin clockwise.
The tail rotor counteracts the torque of the main rotor so the helicopter doesn't spin around.The tail rotor direction also varies with different makes and models, and it's direction may or may not be the same as the main rotor. The tail rotor will be tilted sideways though, so the thrust acts horizontally, instead of vertically. The tail rotor may be on the left or right side of the tail, again depending on the make and model.
Helicopters with two main rotors will have them spinning in opposite directions.

Chinook helicopters, which have the two sets of overhead rotors, have them turning clockwise and anti clockwise. This adds to stability of flight. Basically, the helicopter would itself gradually rotate if it was not for the other rotor turning anti clockwise. Normal helicopters have the smaller tail rotor to compensate for the actual craft rotating.

From what I understand, most turn clockwise when viewed from above... but it depends on who built it!
It doesn't actually matter - any given helicopter could be designed either way, but the rotors would have to be the configured in the correct way. Ie rotors have set leading and trailing edges and they must be spun in the correct direction for them to work! Otherwise it would be like trying to fly a plane backwards...

If you're looking at the rotor from above, they rotate clockwise. From below, they're counter clockwise. If you notice the tail rotor, it's always on left side of the pilot. This is to counter act the clockwise (from above) rotatational torque.

Clockwise.

Clockwise, but it doesnt matter as long as the pitch and tail rotor ballance its ok. Some have two contra rotating sets.
Dont know about the French.

looking down at the aircraft the main rotor looks like it spins counter clockwise looking up from the cockpit the main rotor looks to spin clockwise. hope this helps

Looking from the top down most U.S. designed and built helicopter rotor blades turn in a counter clock wise rotation. French and Russian designed helicopter rotor systems turn in a clock wise direction

the magnificent issue approximately LTE and settling-with-means is they supply lots of warning, and the circumstances are predictable. that is magnificent to be certain somebody attempting to return up with ideas to the subject concerns, however the least confusing, least confusing, and maximum value effectual i've got ever considered is - don't get into them! And in case you do, know the thank you to get out. i've got been in the two, far too many circumstances, and in spite of the undeniable fact that there is warning, there is in no way adequate to have the potential to respond with something greater suitable than an common maneuver. as far by using fact the fixes for gyroscopic tactics, the Chinook and Vertol counteract torque by potential of putting counter-rotating rotor discs fore and aft on the airframe. Produces some interesting engineering problems with the blending of controls, yet takes away the anti-torque rotor. direction, i've got in no way considered a Chinook fly very far with in basic terms one rotor turning. Kaman has tried with a pair of machines (the Husky and Kamax) to mount the blades component-by potential of component and intermeshing. interesting to look at, and somewhat effective, yet high priced and sophisticated. Kamov (Russia) has countless fashions that furnish counter-rotating discs above one yet another, with a mast interior of a mast (very like the shafts interior the turbine engine), yet i've got in no way been around them. curiously as quickly as lower back effective, yet complicated. and that's what all of it comes right down to. The greater complicated, the costlier, and the less possibly it is going to look interior the industry.

They go clockwise. If they went anti-clockwise, the helicopter would go back in time.
