Good question. It is called as "loss of tail rotor efectiveness".
It happens in high grossweight conditions, high rightside crosswind, other any high demand of power conditions.
You may check google for detailed, in better english details.

Re: Bell UH-1
Is there some kind of fancy control that adjusts the tail rotor blade angle as the main rotor blade angle is adjusted by the collective ? ie are they tied in together so as when the main rotor produces more torque the tail rotor produces more counter torque. They are not tied in together. Tail roto...

Re: Bell UH-1
Thesis: Maximum flapping angle is 12.391 degrees. This value is the angle if the blade is stiff. In forward speed, due to the stiffness of the blade, some deflection may occur. Near VNE this deflection angle is at maximum. (No certain info for our models.) https://apps.dtic.mil/dtic/tr/fulltext/u2/a...

Re: Bell UH-1
The mast is tilted 5 degrees forward.
Maximum flapping angle is 15.55 degrees.
If you did so, you are correct as i understand your intention.

Re: Bell UH-1
1- You may be right about faulty animation of the ball. I dont know how to check if it is right or not. 2-You may add "SAS on/off" switch for average and pro "joe" 3-we will see after new update. 4-Perfect 5-Autorotation is not possible with the model. If you lose engines, you ca...
