Change networkView owner not working

Hi,

I have a little multiplayer project, where you can run around and sit in helicopters and fly them. Because the server spawned the helicopters the networkView belongs to him. That's not what I want. Because of this I've read those two posts: this and this. But I'm not able to get it to work.

When the player is in the trigger zone of a helicopter (door) and presses "e", the player is positioned in the vehicle the meshrenderer is disabled and so on. After that I execute this:

 NetworkViewID newID = Network.AllocateViewID();
 triggerCollisionRoot.networkView.viewID = newID;
 networkView.RPC("setHelicopterViewID", RPCMode.Others, newID);

Then in the helicopter script is this:

 [RPC]
 void setHelicopterViewID(NetworkViewID newID) {
     networkView.viewID = newID;
 }

But this isn't even getting called. I tested that with some print()'s. Maybe I'm missing something fundamental?
