Helicopter effects

[agi436]

just started FS, some of the helicopters wobble at higher speeds, does this have to overspeed on bird?, some helicopters speed this happens before actual max speed achieved, is there a way to change this?

I think it's something that cannot be controlled or changed. I've tried it to no avail.

I know that the Bell 206 does shake a little at high speeds. I flew in a Bell 206 around Mt. St. Helens in October and during our return flight back to Hoffstadt Bluffs we flew at around 125KTS above the Toutle River Valley. While we were flying the helicopter shook a little.
