In my opinion and after about 400h in it I would not recommend the H145 for VIP. The LAVCS, which was supposed to be an optional equipment, didnt become standard equipment because Airbus is being generous!
The LAVCS is making the vibration bearable, but its still quite a bad vibration level. Anyone who has flown the H155 will think its broken and anyone coming from an H135 will think someone messed up the tracking really bad.
The other thing is, that the vibration are also creating a deep drone that is very annoying on long flights without active noise cancellation (which we dont use / have in our helmets).
The LAVCS motors have actually ripped themselves out of their mounts in the past, which tells a story on its own.
We end up in an aircraft that has electric motors countervibrating a bad vibration from the main rotor and helmets counterscreaming at us to compensate for drone from the structure...nothing gets to the root of the problem, which would be a redesigned (five-blade) rotor and also a dampened (ARIS?) mount of the MGB to the cell. The Five-Blade-Rotor might do the the trick alone (and it actually does according to some Airbus insiders), but the old BK117 way to attach the MGB is no smart solution either IMO.
