Where is the bend? If it is on the outside portion and the threads and actual needle that go into the carburetor are good then it may still work fine. If not then you will have a problem. Was the package insured? If so maybe you can contact the seller and you can file an insurance claim for the damage?

You can likely get a new needle through Tower Hobbies/Hobbico. There may even be an OS service & parts dealer closer to you or even OS directly.
