Mello,

The most effective thing you can do to get greater/faster steering response is to upgrade that servo. The S3003 servo is Futaba's standard and would be sluggish even in a 10th scale buggy (not to discount their product, this is just the nature of any "standard" servo). If you were to throw in an upgraded servo (in the 50-75 dollar range) you would see a huge difference. Almost any brand will work, ie. Futaba, Airtronics, Hitec...etc. You can find these at many hobbyshops as well as online at sites like towerhobbies.com, horizonhobby.com, ehobbies.com...etc.
