Helicopter blade rotation?

Hey, I’m not sure if this is LUA or not, but is there a way to make the propellers on the combine helicopter models rotate like they do in HL2? If so, please tell me if there is.

They should automatically do it.

I set my player model to one before and it was spinning.

The blades dont rotate I think its a texture that makes it look as if they do

local seq = self:LookupSequence( “idle” )
self:ResetSequence( seq )

The default idle animation has the rotors spinning.

I meant if you spawn the model from the spawn menu.
