if your not using stock radio, check your steering servo throw.
not sure if the revo is the same as my emaxx, but if your dust plugs ( the bottom is blue, and its plastic, you need the plastic wrench that came with the truck, it goes over the pillow balls) is too tight, then it will limit your steering. loosen that and is should be all good. plus, if those things are too tight in the rear, your shocks may not spring back up fully.
