I’ll have to check that out! If it’s vibrating now in 2024 that is a realism improvement!
I don’t have direct experience with the G2 IRL, but every other helicopter I’ve been around on the ramp, the tail slightly vibrates and bounces a little when running due to the vibration from the tail rotor drive shaft spinning inside the boom.
That other X sim has had this since V9 with the dreamfoil R22, and now the default one in V12 as well.
