Systems modeling on the Huey however is somewhat incomplete, like many BST modules some self harm states don't actually exist in this helicopter

For anyone who maybe missed this video when I posted it, here is an example of just such a thing.

TL;DW, the main cause of mast bumping and rotor separation in the Huey when it first went into service cannot be accurately recreated in DCS because the tail rotor drift isn't modeled. Pilots responded incorrectly to a roll triggered by the tail rotor rising above the center of gravity. Without that roll, there is no pilot error and no rotor separation.

Also possibly interesting, it appears Belsimtek copy-pasted chunks of the Huey's flight model and then modified them for the Mi-8 when they did that one, but they forgot to account for the fact that the main rotor on the Russian bird spins the opposite direction to the Huey. So when you trigger a Retreating Blade Stall, the Hip should roll to the right, but instead rolls to the left just as if it were a Huey.
