If hovering in to a 30 kt constant wind then yes: in such a case the helicopter has an airspeed of 30 kts and hence VRS is not a problem. If the air is turbulent then I guess the wind speed and direction would be variable, in which case VRS (and maybe LTE, too) might be a concern.

Thanks for posting the video! A couple of observations: The first few manoeuvres you perform show the helicopter exhibiting static instability. After your roll input the helicopter doesn't show any tendency to want to roll back to the original attitude. Dynamic stability is irrelevant here since the aircraft is statically unstable. The manoeuvre at ~1:40 shows the helicopter returning to the original attitude without pilot input, i.e. it's statically stable. It appears to return to "wings level" with only minor overshoot and is hence exhibiting dynamic stability also. It's difficult to determine exactly what's happening in the remaining manoeuvres since these involve quite drastic pilot inputs. It would be interesting to see: 1. A comparison between SAS on and SAS off 2. The aircraft response with shorter, sharper pilot inputs to mimic, say, a wind gust 3. Control inputs during coordinated turns (with SAS off, applying in-to-turn pedal seems to fix the issue for me) I don't know enough about the Gazelle's stability system to determine if it's working as designed or not. From what you've posted, it seems to be a question of static - rather than dynamic - stability.

At what airspeeds/bank angles does this occur for you? And are you using any pedal during the turns? I've just fired up DCS and can only achieve some slight divergence (with hands off the cyclic) during turns to the left at ~150 km/h and ~30 AoB. Turns to the right require me to keep applying in-to-turn cyclic which is the opposite of what's happening to you!

Is this not because helicopters are dynamically unstable in roll? Once you enter a turn, a number of small corrections will need to be made with the cyclic to keep attitude constant; you shouldn't need to bank violently in any direction. Check out this video - constant attitude turns are certainly possible.

Can you post a video which shows the control inputs you're making at each stage?

The militarised version of the EC145, the H145M, can carry weapons. I'd love to see a "modern" equivalent of the Gazelle/BO-105 with glass cockpit etc.
