Is this a new model from the dealer, (or manufacturer)? If so, you should check into filing a claim with the shipper. This can be quite a hassle, as I experienced with Airborne.
My Ford Flivver ARF arrived a bit damaged, and I gave up trying to deal with Airborne. I can fix the damage for about $20.
On the rudder, were the hinges already glued in? Lots of ARF manufacturers simply install the hinges to the surfaces without glue and then you do the final attachment.
Without being able to see your damage first hand, it is difficult to say how to best go about repairing it. Can you post some pics? That would be best so that we can see the level of damage.
