Pretty sure I mentioned that I applied full left rudder in the original post, to little effect. All it does is slow down the right rotation. Without it, it’ll spin to the right even faster.
I saw this and have been fighting this same issue for a while. It seems there are multiple possible fixes for the heli’s, but what has made a world of difference for me is to reduce the throttle a bit. Look at your center collective and you’ll see the twist throttle, which has a “FLY” setting that you use after startup. If you click and hold that, you can turn it back down. I’m still fine tuning, but setting it at 85 seems to be the most optimal for me right now.
It sounds like the torque of the main rotor at full power overpowers the counter torque of the tail rotor, and reducing the throttle reduces the torque to acceptable levels without loosing a lot of performance. I’ve also noticed that it’s still possible to put in too much left rudder. If I’m light on the left rudder it’s fine. If I go hard left rudder, it’ll lose authority and go back to a crazy right spin. To prevent this, I set the extremity dead zone for the left rudder axis to 25% so I can fully depress the left trigger without applying full rudder in the game (I left the right rudder extremity dead zone alone). This is on a custom heli XBox controller profile, so your ideal settings may be different.
but, that should have not an effect because of the fadac …
Usually the tail rotor needs power too and this power you not have in the main rotor, but depends on helicopter model. The Huey in DCS is for me still a reference and all of these facts are so beautifull “noticable” ( the feeling what happens is better ), e.g. in full load you can only start with help of ground effect, but if you use the tail rotor much while that manoveur you lost again power and you may miss to take off. And there are other situations where the power of the tail rotor is not sufficent to move the heli against the rotor. Therefore you fly curves in such a way, that the tail rotor have no load and not need to fight agains main rotor, the curve and may be the wind ( without usage of the tail rotor the movement is to the right ).
A little reminder: the original bell is currently limited in some facts, eg. rpm, torque, … You can try out the bell improvement mod , may be situation will be better changed then.

Whether or not my changes should have an effect, they did and cleared up most of my issues to the point I could comfortably fly the Bell with the Xbox controller. It may work for others, or it may not, but I wanted to suggest it just in case. Remember, this is still just a sim and not the real thing, and all these complaints of poor helicopter performance indicate an issue with the coding that has a ton of users flustered.
and tons of users not 
… but yes, of course are issues allways possible and the bell have some. Just in my case has the throttle not such an effect, therefore I mentioned the impr. mod. Users can try out all of the given hints.
Definatley not. 
I get the same issues and while I’m certainly no expert, something seems off. I suspect some callibration maybe that you can’t apply the same counter force using the rudder. I’m using an X-56.
Forget the minute, it can happen at anytime once you constantly increase the collective and it just overpowers to tail and goes into what I can only describe as a flat spin. I’ve flown 4 or 5 heli’s in this and other sims in the highest fidelity flight models and I’ve never seen something as consistent as this before.
I my view this appears to be a bug at least with my the control inputs if not the flight model.
