You could try reversing the servo plug on the radio receiver to see if that does anything. You can also get a nice aftermarket servo (Hitec makes decent ones - get metal gears) for probably close of the cost of shipping on returning yours. If there is a local hobby shop in your area, you could go there and have them test the servo and receiver for you and pick up a new servo there if that is the problem.
I did try reversing the servo plug and also tried switching the servo select thing on the remote, nothing. And I was thinking about getting a servo, but what if the problem is in the remote? Like I said, I was messing with the steering trim and that was moving the front tires just fine. I just couldn't move them with the steering wheel on the remote.
Maybe I will call the local hobby shops. Thanks for the suggestions.
