Multichannel Problem On Helicopter Main Rotor

[ghasemimor]

I have a problem on using multichannel functionality on a helicopter.
Everything is OK on client computers . even Blade lights on top of blades are synchronized to Server, but Rotor speed and rotor rotation angle does not.
When I set Main Rotor RPM on server using "ROTOR RPM PCT:1" Main rotor on server slow down but on multichannel clients Rotor RPM does not change and rotate with maximum speed.

Thanks
