Vibrations for all the flight

[crim3d]

The other day I was doing some funny flights with the Robinson helicopter. I had the full throttle vibrations on in that profile, and at the lift off the stick was shaking in a way that I felt it was very close to how a stick from this kind of aircraft should do, but, of course, the vibration dissapears at the moment the skids are not touching the ground.

So, I think it would be great to have a vibration that is associated only to engines rpm's and it's played all the time no matter you are on the ground or flying. Something like low frequency and wide amplitude at idle and high frequency and smaller amplitude with high regimes. More or less.
