One thing i find slightly off-putting that if a pilot is shot and killed during flight, the chopper seemingly just powers off, and falls right down.

Why is there never a possibility that the pilot could in fact move his body in some random posture, or fling his arms around? I would imagine that a pilot could flop, when for example having his head blown into bits, either like forward or to one of the sides, randomly effecting joystick and/or throttle?

I think it's important to implement a new mechanism to change the way that choppers fall out of the sky if the pilot dies.

Having three factors to be randomly influenced. Rudder pedals, the joystick and the throttle?

An example:

Rudder Pedals - Nothing happens/unchanged*, rudder full left or rudder full right.
Joystick - Nothing happens/unchanged*, nose down full, nose up full, bank left full or bank right full.
Throttle - Nothing happens/unchanged*, 100% throttle, 50%/neutral throttle or 0% throttle.

*Having the controls on whatever it was the moment before the pilot was killed.

Having this really unpredictable behavior, in my opinion, would mean alot to a military/warfare simulator. It would add so much to the fact of how quickly things can change on a battlefield.
